Chapter 13: Ch03 Examining Witnesses Direc RIEHL EDUTS

Direct examination lets the witness tell the story; cross controls the witness through short, leading, one-fact questions; expert examination layers credentials, basis, and opinion so the fact finder can adopt the conclusion as their own.

Direct Examination

A. Scope

1.01 Why Be Direct?

The purpose of direct examination is to allow witnesses to tell their stories. Direct examination should present evidence that is: (1) legally sufficient to survive a motion for judgment as a matter of law, (2) easily understood and readily remembered, (3) quite credible and convincing, (4) strong enough to survive cross-examination, and (5) able to counter or contradict evidence submitted by the opposition.

1.02 What Is the Evidence?

Several primary evidentiary factors apply to direct examinations: competency, relevancy, foundation, reliability, and form.

1.02.1 Who Is Competent?

A witness must satisfy four requirements to be competent to testify:

 Oath or Affirmation. The witness must understand the meaning of an oath or affirmation and agree to tell the truth.

 Perception. The witness must have personally perceived something that is relevant. See [FRE 602](https://www.westlaw.com/Document/N5B090D30C0F511D8A8CA80DCF7582C6A/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N5B090D30C0F511D8A8CA80DCF7582C6A/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0).

 Recollection. The witness must be able to remember what was perceived.

 Communication. The witness must be able to communicate through words or through an interpreter.

1.02.2 What Is Relevant?

Relevant testimony has a tendency to make more or less probable any facts of consequence to the case. [FRE 401](https://www.westlaw.com/Document/N4DE88ED0B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N4DE88ED0B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0). If the testimony is relevant, it has probative value and is admissible. [FRE 402](https://www.westlaw.com/Document/N50FE3340B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N50FE3340B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0).

Relevant evidence may be excluded in some circumstances, including:

 Prejudicial value outweighs its probative value, confuses issues, causes undue delay, or is needlessly cumulative ([FRE 403](https://www.westlaw.com/Document/N5CA04210B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N5CA04210B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0))

 Improper character evidence ([FRE 404](https://www.westlaw.com/Document/N75F628B0B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N75F628B0B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0) and 405)

 Improper habit evidence ([FRE 406](https://www.westlaw.com/Document/N9FAD53E0B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N9FAD53E0B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0))

 Subsequent remedial measures ([FRE 407](https://www.westlaw.com/Document/NA1FB3B80B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/NA1FB3B80B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0))

 Offers of compromise ([FRE 408](https://www.westlaw.com/Document/NA5A88C10B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/NA5A88C10B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0))

 Payment of medical expenses ([FRE 409](https://www.westlaw.com/Document/N3B0407B0C0F511D8A8CA80DCF7582C6A/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N3B0407B0C0F511D8A8CA80DCF7582C6A/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0))

 Plea bargains ([FRE 410](https://www.westlaw.com/Document/N3B4CA970C0F511D8A8CA80DCF7582C6A/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N3B4CA970C0F511D8A8CA80DCF7582C6A/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0))

 Liability insurance ([FRE 411](https://www.westlaw.com/Document/N3C5762B0C0F511D8A8CA80DCF7582C6A/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N3C5762B0C0F511D8A8CA80DCF7582C6A/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0))

1.02.3 What Is Foundation?

Foundation consists of the detailed facts that establish the reliable source of the evidence. Information based on unknown or unreliable sources is inadmissible.

1.02.4 What Is Reliable?

The evidence introduced through direct examination must be assessed to determine its reliability through an analysis of its content:

 Does the witness have personal knowledge of the matter? ([FRE 602](https://www.westlaw.com/Document/N5B090D30C0F511D8A8CA80DCF7582C6A/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N5B090D30C0F511D8A8CA80DCF7582C6A/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0))

 Has sufficient information been provided to establish the source of the information? ([FRE 901–903](https://www.westlaw.com/Document/N523F5E70B97011D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N523F5E70B97011D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0))

 Is the opinion testimony rationally based on the perception of the witness? ([FRE 701](https://www.westlaw.com/Document/NEC4C3220B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/NEC4C3220B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0))

 Is the out-of-court statement not defined as hearsay? ([FRE 801](https://www.westlaw.com/Document/N7628C6F08D6211EFB96292A2D3FA2FFC/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N7628C6F08D6211EFB96292A2D3FA2FFC/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0))

 Or, is the testimony admissible based on an exception to the hearsay rule? ([FRE 803 & 804](https://www.westlaw.com/Document/N04E853C0B97011D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N04E853C0B97011D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0))

1.02.5 What Is the Proper Form?

Direct examination questions must be understandable, seek admissible evidence, and not be objectionable. A variety of objections may be available if the direct examiner asks improper form questions. See Chapter 4, § 2.01.

Cross-examination questions similarly must be coherent, seek relevant evidence, and not be objectionable. Practically, there are fewer objections made during a cross-examiner’s inquiries compared to direct examination. See Chapter 4, § 2.02.

B. How to Prepare

1.03 The Plan

Preparation begins with a review of the legal theories, facts, and significant issues of the case.

1.03.1 The Legal Theories

The legal elements of a claim or defense provide a basis for the testimony and the facts necessary to prove them. GenAI can map each element to witnesses and exhibits and can even output a per-element evidentiary checklist.

1.03.2 The Factual Story

The direct examination must allow the witnesses to describe from their own knowledge the facts and opinions supporting the legal theories.

1.03.3 The Significant Issues

Witnesses must be identified who can testify about the relevant issues.

1.03.4 The Right Questions

Effective direct examination questions may be prepared in a topic outline or a list of specific questions, or with a combination of topics and questions.

1.03.5 Practice and Rehearsal

The advocate can practice by asking questions in a sequence, following the prepared direct examination. Further preparation requires practicing the questions with the witness providing answers, working on both content and form.

1.03.6 GenAI and Direct Exam Preparation

GenAI can help match elements to the witness’s facts and propose chronological or topic-by-topic sequences to best elicit facts. Tools can flag gaps and hearsay risks, as well as draft non-leading questions. For rehearsal, an LLM can role-play the witness, including realistic personas (e.g., shy, reticent, loquacious). And GenAI-backed tools can: coach pacing, refine clarity, tighten question economy, spot leading phrasing, and suggest clean rephrasing.

C. How to Prepare the Witness

1.04 Selecting Witnesses

Consider which witnesses can make the most effective and compelling presentation and then determine their order. Review what each witness knows that is relevant to the case. Identify exhibits to determine which ones need to be introduced through this witness. Consider using demonstrative evidence to help the witness tell their story. LLM-backed tools can assess potential witnesses based on their anticipated testimony, knowledge, and demeanor.

1.04.1 What Information to Obtain

Ascertain:

 The ability of the witness to observe, remember, and communicate

 What facts the witness knows

 What opinions the witness has

 What exhibits the witness can identify

 What exhibits can be created to help the witness testify

 What prior statements the witness has made

 What weaknesses may be established by the cross-examiner

 What prior testimonial experience a witness has

1.04.2 Method of Preparation

The goal of witness preparation is to assist the person testify truthfully and credibly. Advocates can meet in person with the witness in order to prepare properly, or, if necessary, by remote video or phone and later in person. The more critical the witness, the more thorough the preparation must be regarding the testimony and the use of exhibits. Preparation methods vary and will be shaped by the circumstances, availability, and situation of the witness. GenAI can generate topic trees and non-leading question lists, and tools might also adapt phrasing for witnesses who are nervous, multilingual, or hostile.

1.04.3 Here Is the Direct

Witnesses must know what is expected and what will happen. Explanations include:

 The stages of the proceedings

 Role of the participants

 Objection process

 Trial and hearing procedures

 How real evidence is to be introduced

 How demonstrative evidence is to be used

 What counsel may do if the witness forgets

 The need to testify only to what the witness knows

 The importance of not speculating or guessing

 Avoiding the appearance of memorized answers

1.04.4 Here Are Directions

Instructions for a witness include:

 Approach the witness box confidently

 Tell the truth

 Speak clearly and loudly enough to be heard by all

 Recreate the details of specific events in your mind

 Relive the experience in your mind and tell that story

 Listen carefully to questions

 If you do not understand a question ask for clarification

 Answer with responsive answers

 Use your own appropriate words

 Imagine you are having a conversation with the fact finder

 Make eye contact with the fact finder, if possible

 Answer the question asked without questioning why

 Use exhibits to help tell your story

 Be aware of body posture and demeanor

 Dress neatly as if attending a serious event

 Do not rely on notes unless counsel instructs you

 Stop immediately when a lawyer objects

 Do not make distracting gestures or facial expressions

 Ask for a break if you feel ill or need to use a restroom

1.04.5 Here Comes the Cross

Directions the advocate should give before a witness responds to cross-examination questions include:

 Listen carefully to the questions

 Answer directly

 Do not ramble

 Testify only to personal knowledge

 Testify only to your best recollection

 Do not exaggerate

 Take your time

 If information is contained in a document and you are uncertain of an answer, ask to see the document, or say you are uncertain

 If a question is repeated from a deposition or prior statement, and you are uncertain about the answer, ask to see the statement or say you do not recall if uncertain

 Expect the cross-examiner to obtain some information that may weaken your story

 Do not allow the cross-examiner to put words in your mouth

 Correct misstatements when possible

1.04.6 Role of the Client

A client who is present throughout a proceeding needs to be advised about specific procedures: pay attention, avoid visibly overreacting to evidence, do not interrupt or otherwise misbehave, and be aware that the fact finder observes all conduct. Counsel can advise the client during the case, and the client can make notes to pass to counsel.

1.04.7 Whom to Call When

The order in which witnesses testify is a critical aspect of how a case is best presented. Witnesses may be called in an order that supports a chronological presentation of the case or best supports the flow of supportive evidence. The primacy/recency effect suggests that a strong witness is most effective when called first or last. Alternatively, a strong witness can be called immediately before a recess or after a weak witness to bolster the evidence. LLMs can be helpful to propose a witness order that makes sense chronologically or that ties together legal theories.

1.04.8 Make Sure They Show Up

The advocate is responsible for witnesses to appear on time and as scheduled. Counsel needs to employ a system to ensure that all witnesses who will testify on direct examination have been contacted and subpoenaed to ensure their attendance.

D. Presenting the Direct

1.05 What to Do

The rules of the forum have established protocols that govern the advocate’s location and movement during direct examination. If preferred, counsel may ask permission to ask questions while standing or sitting, and should select a place that permits effective communication.

1.05.1 How to Approach the Witness

Judges and arbitrators allow advocates to approach the witness to show the person an exhibit. Some judges require advocates to ask permission to approach the witness.

1.05.2 What Is Appropriate?

The formal procedures of conducting direct examination are established by the applicable rules of evidence. Informal rules and preferences by the judge, arbitrator, or hearing examiner may also affect how direct examination proceeds, and counsel needs to comply with these expectations unless unreasonable.

E. How to Compose Direct Examination

1.06 Organizing the Direct

Every direct examination must be organized in a manner that most effectively achieves its purposes.

1.06.1 The Beginning

Beginning testimony must be interesting and hold the attention of the fact finders when they are most alert and prepared to listen. A common way to start is to ask a reasonable number of questions to personalize the witness. An effective way to continue is to seek answers from the witness relevant to the case blended with responses that describe their background germane to the evidence. This sequence helps the story unfold while revealing information about the witness that enhances credibility. See § 1.08.1. LLMs can draft story-first outlines that start with pivotal events and might interleave background only when it serves legal strategy (e.g., proves an element, demonstrates a defense).

1.06.2 Structure

The direct presentation must be simple, clear, and easy to follow. Optional structures include:

 Chronological order

 Elements of claim or defense

 Flashback

 Sequence of supportive evidence

 Combinations of the preceding approaches

F. Asking Appropriate Questions

1.07 Proper Questions

The goal, of course, is to ask proper and appropriate questions and to avoid objectionable queries. There are various types of direct examination questions.

1.07.1 Leading Questions

A leading question is a question that suggests and contains the answer. FRE 611(c) and similar state rules permit leading questions when they are necessary to develop testimony. Leading questions are permitted if they:

 Bring out preliminary matters

 Establish noncontroversial or inconsequential facts

 Suggest new topics

 Act as transitions

 Establish negative facts

 Are asked of an adverse witness

 Are asked of a hostile witness

 Help a witness who has communication difficulties

 Refresh a witness’s recollection

 Use specific words to lay an exhibit foundation

 Lay a foundation for past recollections

 Are asked of a witness to contradict a statement made by another

A careful use of permissible leading questions may achieve positive results. They can help by:

• Suggesting familiar and appropriate topics to a witness
• Reasonably accelerating the presentation of evidence
• Introducing variety into the examination
• Demonstrating the advocate’s honesty when used to elicit negative facts
• Demonstrating the advocate’s knowledge of the facts

Leading questions have disadvantages. They do not allow the witness an opportunity to testify and may prevent the witness from appearing credible. They sound as if counsel is testifying, and their use may interrupt the flow of testimony because they draw an objection. Leading questions should be used sparingly to avoid these problems. GenAI can rewrite questions to remove leading language on direct, proposing permissible lead-ins.

1.07.2 Narrative Questions

A narrative question invites a properly prepared witness to describe what they saw, heard, observed, felt, and concluded. An effective narrative inquiry is most effective when it is focused and directed. An overly broad question reduces the ability of the direct examiner to control the direction or scope of the response and allows the witness to respond with an unfocused and rambling answer. And a lengthy narrative response can deny the opponent the opportunity to anticipate and react to objectionable evidence. LLMs can translate jargon into plain language, adding short “teach-back” checks that confirm understanding without inviting narrative sprawl.

1.07.3 Specific Questions

Witnesses can more readily respond to questions that are easily understood because they are simple and clear and seek precise and concise information. The less specific and targeted the query, the more difficult it is for the witness to formulate the sought-after answer.

1.07.4 Objectionable Questions

As described later, common problems that make questions objectionable include queries that are vague, ambiguous, confusing, compound, and repetitious. The obvious solution is to ask appropriate questions to avoid these infirmities.

G. How to Enhance Persuasiveness

1.08 Compelling Questions

This section presents a variety of questioning techniques that can be employed to conduct an effective direct examination.

1.08.1 Use Background Questions

The extent and number of permissible background questions depends on the significance of the witness and the time available. See § 1.06.1 Questions regarding a witness’s background can accomplish the following:

• Relieve initial anxiety and build confidence
• Establish a witness’s personality
• Bolster credibility and foundation
• Display the sincerity of the witness
• Identify similarities between the witness and fact finder

1.08.2 Putting Witness at Ease

The witness may be more comfortable testifying about themselves than about the facts of the case. Background testimony concerning familiar matters permits the witness to overcome initial nervousness.

1.08.3 Portraying a Witness’s Personality

A witness’s personality can be demonstrated through background questions. The witness has the opportunity to portray themselves allowing the fact finder to become familiar with the individual’s character and persona.

1.08.4 Establishing Credibility and Sincerity

Credibility and honesty can be established and enhanced by having witnesses reveal themselves to fact finders by using their own words in sincerely telling their story.

1.08.5 Identifying Similarities Between the Witness and the Fact Finder

Questions can be asked that reveal similarities between the backgrounds or interests of the witness and the fact finder. These connections can help develop perceptions that the witness is believable.

H. How to Lay a Foundation

1.09 How Does the Witness Know?

Questions need to be initially asked of a witness to establish a foundation for how and why the witness knows what they are about to proffer as evidence.

1.09.1 Establish Foundation

Facts must be established that show the witness actually saw, heard, felt, sensed, or did what they are about to reveal.

1.09.2 Enhance Foundation

Foundation questions should be asked to add details that enhance the accuracy, completeness, and reliability of the story told by the witness.

1.09.3 Establish Foundation to Support an Opinion

Before an opinion can be rendered, the witness needs to be asked questions that establish the witness reasonably perceived events and knows sufficient information to support the opinion or conclusion.

1.09.4 Set the Scene

The scene can be initially established allowing the fact finder to visualize the place, surroundings, and location.

1.09.5 Describe Vivid Details

Details are critical because they supplement the scene and describe the action. The amount of detail presented must be proportionate to its evidentiary value: substantial details for critical issues and modest details for lesser issues.

1.09.6 Detail the Action

It is often easiest for a witness to describe events as they happened, and also the easiest way for the fact finder to understand what happened. The action may initially be described in broad terms to set the scene and provide context. The action can then continue with descriptive testimony and demonstrative exhibits completing the action story.

1.09.7 Establish Conversations

Conversations can be established by asking who said what to whom when and in what order. Face-to-face and video conversations can speak for themselves. Telephone or recorded conversations require the witness to identify the voice of the other person.

Eliciting the exact words in critical conversations is more believable than a generalized “What did you talk about?” The former approach has the witness or witnesses testify sequentially: “Who spoke first? Then who said what? Was anything else said?” The latter summary method may be sufficient for less critical conversations.

1.09.8 Present Admissible Habit Evidence

Evidence of a particular habit of a person or the routine practice of an organization is admissible in some cases to prove that a person or organization acted in conformity with that habit on a particular occasion. See [FRE 406](https://www.westlaw.com/Document/N9FAD53E0B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N9FAD53E0B96D11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0).

1.09.9 Introduce and Use Exhibits

Exhibits can help bolster the story being told by the witness. Exhibits that are real evidence need to be introduced through a witness. Demonstrative exhibits such as lists or charts can be created to help illustrate testimony. See Chapter 4, § 4.01. Computer programs or digital portrayals may be used to enhance the testimony of a witness. Parts of an exhibit can be highlighted and shown to the fact finder as a witness testifies about that exhibit. Parts of a story can be enhanced after a witness has testified verbally about an event by introducing an exhibit that allows the witness to testify to additional factual details.

I. How to Ask Questions Effectively

1.10 Ask Understandable Questions

Simple, common conversational queries are quite effective because they are easy to understand and answer and easier for the fact finder to follow and comprehend. Additional variations can enhance the story.

1.10.1 Pose Succinct Questions

Concise questions make it easier for a lawyer to control testimony and for a witness to be responsive.

1.10.2 Use a Variety of Questions

A mix of short narrative and specific questions provide variety and help develop a complete story.

1.10.3 Complete a Sequence

Omitted information can be introduced at the end of a sequence to avoid interrupting the flow of testimony.

1.10.4 Use Impact Words

Impact words are graphic words that vividly describe something in support of a perception or conclusion. A careful choice of impact words can have a positive effect on how testimony is perceived and remembered.

1.10.5 Rely on Double Direct

“Double Direct” is a technique in which part of the previous answer is used as a preface to the next question. This format can be used to emphasize a previously significant answer.

1.10.6 Listen Carefully and Correct Mistakes

When a witness does not answer a question precisely or makes a mistake, the examiner must correct the witness by asking a follow-up question.

1.10.7 Explain Terms

The direct examiner should make sure the witness explains terms that have specialized or multiple meanings.

1.10.8 Enhance Credibility

Witnesses do not—and ought not—have perfect recollection. They may actually lose credibility if they appear to recall every detail. A forthright occasional admission of an inability to remember may help a witness appear more believable.

1.10.9 Volunteer Weaknesses

Weaknesses in the background or story of a witness may be briefly presented during the direct examination to minimize the impact of its likely or inevitable reveal during cross-examination, and to enhance the credibility of the witness and the advocate.

1.10.10 Employ Exhibits

When carefully planned and effectively used, real and demonstrative evidence and visual aids will enhance the testimony of a witness. The key to successfully introducing exhibits is to weave them seamlessly into the story being told by the witness. If exhibits break up the pace and flow of a story they can be counterproductive. See § 1.09.9.

1.10.11 LLMs and Question Simplification

LLMs excel at simplification: The model can be instructed to rewrite questions at an understandable level, strip jargon, and convert compound questions into simple queries. GenAI can review draft questions and flag ambiguity, passive voice, and stacked clauses—suggesting tighter, listener-friendly questions. This AI tool can also swap abstract verbs for concrete impact words and replace or augment technical terms with plain English. The simpler output can help counsel control testimony, maintain pace, and make questions easy to both understand and answer.

J. How to Conduct a Redirect

1.11 The Extent of Redirect

The advocate needs to review the testimony and evidence and consider what further examination is needed.

1.11.1 What Can Be Asked?

The direct examiner has an opportunity to conduct a redirect examination after the completion of cross-examination. Redirect allows the witness to clarify or explain points and to cover new material raised by the cross that was not covered on direct. Redirect examination may not repeat direct examination responses.

1.11.2 What Should Be Asked?

When considering whether to use redirect, consider what may go wrong: the witness may not be prepared to answer the question; the witness may misspeak; getting the last word may backfire; nothing useful may be added; summation may be a more appropriate time to clarify and emphasize certain points. Redirect also gives the opponent the opportunity for a recross-examination.

1.11.3 How to Ask

The same evidentiary rules apply to both direct and redirect examination. But there may be greater latitude with using leading questions during redirect to permit the advocate to focus the examination. The leading question can refer to the question asked on cross to help the witness and fact finder understand the point of the redirect.

1.11.4 How to Correct Mistakes and Refresh Recollection

Redirect provides the opportunity to correct mistakes made by the witness on cross-examination and to explain testimony that was restricted during cross.

1.11.5 Reserving Evidence for Redirect Examination

It is potentially risky to save worthwhile information for redirect. Decision makers may not allow withheld evidence to be subsequently raised on redirect if not addressed during cross. There are occasions when the risk may justify reserving testimony. Damaging information could be omitted if it’s likely the cross-examination will not cover it, or positive information could be reserved if it is certain the cross-examiner will introduce the topic.

K. Direct Examination Assistance

1.12 Some Witnesses May Require Testimonial Assistance

1.12.1 Former Testimony

In civil trials, the testimony of a witness may be introduced through former testimony given under oath at a deposition or another hearing. The introduction of prior testimony may be allowed when a witness is unavailable or unable to recall past events. A deposition transcript may be read or a deposition video shown to the fact finder.

1.12.2 Past Recollection Recorded

A past recollection recorded may be introduced if the witness has lost the capability to recollect. See [FRE 803(5)](https://www.westlaw.com/Document/N04E853C0B97011D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N04E853C0B97011D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0). The foundation includes the following:

• Witness has no present, independent recollection
• Witness once knew relevant information
• Witness accurately wrote down or recorded the information
• Information was created or adopted by the witness while still fresh in the witness’s memory
• Witness authenticates written or recorded information

1.12.3 Witnesses with Communication Issues

A child or witness with communication concerns requires special consideration. Leading questions are permissible; however, numerous leading questions can and will reduce the credibility of the witness.

L. Character Evidence

1.13 Character Evidence

Character evidence is typically not admissible. It may be relevant, but the unfair prejudice and confusion of the issues resulting from character evidence commonly outweighs the probative value of such evidence. See FRE 404 and 405.

1.13.1 Character Evidence in Civil Matters

While character evidence is usually inadmissible in civil cases to prove a person acted in a particular way, it may be admissible if it:

• Proves motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake.
• Is offered to show character for untruthfulness against a testifying witness.
• Counters evidence of untruthful character.
• Directly relates to issues of liability or damages.

1.13.2 Character Evidence in Criminal Cases

In criminal cases, character may be admissible in limited situations:

• When offered by an accused as a relevant trait, such as peacefulness in a self-defense case.
• When offered by prosecution to rebut character offered by the defendant.
• When offered by the defense in very limited cases with regard to a victim.
• When offered by the prosecution to rebut a victim’s character.
• When offered to show character of untruthfulness of a testifying witness.
• When offered to counter evidence of untruthful character.
• When offered to prove motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake.

1.13.3 How to Introduce Character Evidence

There are three ways in which character evidence may be introduced during direct examination:

• Opinion testimony. A witness may testify to a personal opinion about the character of a person if a foundation is established relating what the witness knows or has observed about the person over a period of time.
• Reputation testimony. A witness can testify to the reputation of a person in a community if a foundation is established relating what the witness has heard expressed about that person in a defined community. Reputation is the expressed community consensus about an individual.
• Specific instances of conduct. A witness may testify to firsthand knowledge about a person’s behavior regarding honesty.

M. Complex Cases

1.14 Direct Examination in Complex Cases

The same rules and techniques apply in complex cases as in common cases. The challenge is to use these approaches effectively to make complex issues clear and understandable. While there will be more witnesses, complicated exhibits, and conflicting experts, the key is to divide the case into distinct evidentiary story segments and rely on the opening and summation to provide a comprehensive overview of the case.

N. What Cannot Be Asked

1.15 Limitations and Objections

There are various reasonable limitations on proper direct exam inquires.

1.15.1 Facilitating the Presentation of Perjured Testimony

The knowing use of fraudulent, false, or perjured testimony is prohibited. The Model Rules of Professional Conduct prohibit such use, as do ethical norms and common sense.

1.15.2 Soliciting Inadmissible Responses

The direct examiner must comply with the exclusionary rules of evidence and cannot prompt an inadmissible response, even with a question that itself is not objectionable.

1.15.3 Oops

Inadvertent blurting out of inadmissible evidence by the witness must be stopped by the direct examiner as soon as it becomes evident. The examiner bears responsibility for the introduction of evidence and must interrupt improper testimony.

1.15.4 Allowing the Witness to Disrupt a Proceeding

The advocate must control a party or witness and bears responsibility for disruptive behavior. Counsel who does not control a party may be sanctioned and may be cited for contempt along with the witness.

1.15.5 Using Tricks to Confuse Identification

The deliberate substitution of someone other than a party to a proceeding to confuse identification by a witness is improper. But prior disclosure to the court may permit this tactic if a legitimate reason exists for its use.

1.15.6 Objectionable Questions

The rules of evidence establish what questions can be asked and what answers are admissible. Varied and numerous objections may be made to direct examination questions. See Chapter 4, § 2.01.

Cross-Examination

A. Scope

2.01 Types of Cross-Examination

Cross-examination allows the advocate to thoroughly examine an opposing party or adverse or hostile witness. The purpose is to obtain necessary information for summation. The goal is to reveal evidence that supports the cross-examiner’s case and discredits the opposing party’s case. There are two types of cross-examination—supportive cross and discrediting cross.

2.01.1 Supportive Cross-Examination

Supportive cross-examination seeks to develop information helpful to the cross-examiner’s case. The advocate needs to consider: what information the decision maker needs or expects to hear and see from the witness, what admissible evidence the witness knows, what admissions the witness can make, what information the witness has that corroborates constructive evidence, whether the witness can bolster the credibility of favorable witnesses, and what portions of the direct examination of the witness were helpful.

2.01.2 Discrediting Cross-Examination

The purpose of discrediting cross-examination is to show that a witness is not credible and that testimony and evidence introduced by the opposing party is inaccurate, incomplete, inconsistent, implausible, improbable, impossible, or unbelievable.

2.01.3 Supportive and Discrediting Evidence

Sometimes evidence can be both helpful to the case and harmful to the opposition. For example, if a witness has made a prior inconsistent statement, that statement could be introduced either to refresh recollection (because it helps the case), to impeach (because it diminishes the credibility of the witness), or both.

2.01.4 GenAI and Cross-Examination Crafting

LLMs can propose cross-examination questions that embed evidentiary and legal nuances, all while keeping questions short, focused, and leading enough to control the witness. LLMs can target supportive admissions or surgical impeachment material—all while using neutral, respectful phrasing that lowers the courtroom temperature, avoiding any appearance of badgering. These modern tools can help draft legally sharp questions that land cleanly, protect credibility with the fact finder, and helpfully avoid making counsel sound overly aggressive or impolite.

B. Strategic Considerations

2.02 Cross-Examination Concerns

2.02.1 Risks of Cross-Examination

Cross-examination should be conducted with realistic expectations and with an assessment of the inherent risks. Potential risks can be avoided or reduced by asking effective leading questions, anticipating responses, and controlling the adverse, hostile, or uncooperative witness.

2.02.2 The Need for Good-Faith Basis

An advocate must have a good-faith basis for cross-examination questions. Counsel must have proof of the underlying facts and cannot fabricate or assert false innuendoes or untrue inferences on cross-examination.

2.02.3 “Uncross” Demeanor

Combative or angry cross-examination is usually ineffective. Composure, persistence, compassion, confidence, and appropriate assertiveness make an examination effective and persuasive.

2.02.4 Common Myths About Cross-Examination

There are various myths regarding cross-examination that, if believed, can reduce its effectiveness:

• Cross-examination should always be short. . .or long.
• The cross-examiner need not be compassionate.
• Cross should always be conducted aggressively
• The story the witness spins must be destroyed.
• The witness should always be shown to be a liar.
• Cross is an opportunity to debate with the witness.
• Cross-examination should result in the witness “confessing.”

With proper preparation and avoidance of these myths, an advocate can conduct an effective cross.

C. How to Prepare

2.03 Planning

The preparation of cross-examination topics and questions begins early in the case and continues until the moment cross begins. The cross-examiner listens carefully to the direct examination and adds, deletes, or modifies questions to be asked during cross. Adjustments may also be necessary during the cross-examination itself.

2.03.1 Should There Be a Cross-Examination?

Witnesses usually merit cross-examination questioning. It is rare not to cross-examine a witness.

The extent of the cross depends on:

• What supportive information the witness knows.
• Whether the witness has significantly damaged the case.
• How important the witness is to the opponent.
• Whether cross will reveal information harmful to the case.
• What cross-examination will the fact finder expect.
• How difficult the witness will be to cross.

2.03.2 Full and Fair Opportunity to Cross-Examine

An advocate has a right to cross-examine a witness fully and fairly. Unusual situations may arise that prevent cross-examination—when a privilege has been asserted, when illness makes a witness incapacitated, or when a witness refuses to answer. These issues may be resolved by a motion brought to allow or reduce the extent of cross.

2.03.3 What Is the Scope of Cross-Examination?

Judges, arbitrators, and hearing officers have broad discretion to permit inquiries into all relevant matters. The scope of cross-examination is usually limited to the subject matter of direct examination and matters affecting the witness’s credibility. Beyond that, cross-examination may be restricted.

2.03.4 Preparing Topics and Written Questions in Advance

Cross-examination is most effective when topics and questions are prepared in advance. The extent to which specific written questions should be prepared depends on the nature of the question, the significance of the topic, the type of witness, and the abilities of the advocate. An LLM can compile a cross dossier—admissions, prior statements, and inconsistency targets—and might simulate answer trees with alerts on what to avoid. This AI tool can draw on cross-exam queries previously used successfully and revise those queries for factual relevance to the current case.

2.03.5 Selecting Exhibits

An exhibit that provides supporting information can be introduced through or shown to an opposing witness who is familiar with the exhibit by asking leading questions. The exhibits should be introduced during the testimony when relevant to the topic being examined. See Chapter 4, § 4.01.

2.03.6 LLMs and Cross-Examination Preparation

GenAI can turn a witness’s record into a cross-examination plan: it can analyze whether to cross, draft topic trees, and tie each question to a cite, element, or credibility attack. If the AI model has the witness’s prior statements and depositions, the tool can build an “admissions and inconsistencies” dossier, simulate answer paths with “one-question-too-many” warnings, and suggest tight redirects for likely evasions. LLMs can also propose scope objections and the bases for short motions when privilege, incapacity, or refusal might prevent a full and fair cross. For exhibits, AI can compose foundations and publication steps, generate impeachment scripts with page-number citations, and sequence your “show then ask” questions to maximize impact.

D. Structure and Order

2.04 Cross Organization

Cross examination topics and questions need to be well structured and ordered.

2.04.1 How Should Cross Be Structured?

Cross-examination questions ought to be asked in an order that makes the cross comprehensive, persuasive, and memorable.

A structuring technique is to:

• List all the points expected to be made.
• Divide the points into the two broad categories of cross-examination—supportive and discrediting cross.
• Rank the points in each category from most to least important, from strongest to weakest.
• Reorganize the order of points into a final format.

2.04.2 How Should Cross Be Ordered?

If both types of cross-examination questions—supportive and discrediting—are to be used (and usually are), the supportive questions ought to be asked first. The witness is more likely to be cooperative at the beginning of a cross and the fact finder may be more likely to believe the supportive responses before the credibility of the witness is diminished. An alternative to a logical sequence of planned questions is to probe areas in a random fashion, which approach can be difficult to conduct well and may confuse the fact finder.

2.04.3 Where Should Cross Be Conducted?

The cross-examiner should be visible and conspicuous during the examination. The best location (standing or sitting) and movement strategy (at counsel table or the witness stand) depends on several variables, including placement of witness, introduction of exhibits, use of visual aids, position of fact finder, ability of the advocate, and rules and limitations placed on the examination by the judge, arbitrator, or hearing officer.

2.04.4 How Should Cross Be Concluded?

The concluding questions of a cross-examination should end on a high note, should not be objectionable, and should be the type the witness will respond to agreeably.

2.04.5 Recross Examination

The scope of recross-examination is limited to the subject matter of the redirect. The rules and strategies governing recross are the same as cross-examination. There may be no need to conduct a recross-examination, and recross should not be conducted merely because some redirect questions were asked.

E. Tactical Considerations

2.05 Comprehensive Approaches

Effective cross-examination requires the use of proper tactics and techniques.

The advocate must consider:

• The form of the question
• The content of the question
• Seeking agreement with witness
• Controlling the witness’s responses
• Emphasizing points
• Asking safe questions
• Preparing questions for specific witnesses

The following sections explain these techniques in detail. These approaches reflect principles that should be followed and not ordinarily be violated. An LLM can suggest how these goals can be accomplished with a particular witness.

F. Form of the Questions

2.06 Precise Questions Produce Favorable Responses

2.06.1 Lead the Witness

Questions that suggest the answer and elicit “yes” or “no” answers should be asked on cross to control the testimony. An effectively phrased question contains the answer, which the witness must affirm or deny. It is best usually not to ask “why,” “how,” or “explain” questions.

2.06.2 Use Simple, Short Questions

Short, straightforward leading questions in simple understandable language are most effective. Lengthy, rambling, leading questions are confusing and often receive lengthy, rambling, and unwelcome answers.

2.06.3 Avoid Multiple Negative Questions

Questions that contain double or multiple negatives are confusing, misleading, and improper.

G. Composing Questions

2.07 Specific Tactics Improve Cross Queries

2.07.1 Ask Factual Questions

Questions that comprise specific facts prompt responsive answers because: the statement is true, or evidence exists to prove the fact, or the witness previously made the statement. Questions that include words or phrases that are subjective or conclusory permit the witness to evade or explain an answer and should be avoided.

2.07.2 Properly Ask for Opinions

An effective way to compel a witness to provide an opinion is to first establish the factual basis that compels the witness to agree with the examiner’s proposition. Once the foundation questions are established, the witness will be or feel compelled to agree with the reasonable conclusion or risk losing credibility.

2.07.3 Use Modifiers

The use of selective adjectives and adverbs as modifiers may help in obtaining favorable responses from a witness. If a witness agrees they were tired, they may likely also agree they were “very” tired.

2.07.4 Employ Synonyms

If the cross-examination seeks to compel the witness to agree with a specific word or phrase, suggesting a synonym may be useful instead of trying to force the witness to admit specific language. A witness may not agree to being “exhausted,” but will agree to being “tired” or “fatigued.”

2.07.5 Be Appropriately Respectful

Witnesses ordinarily deserve courteous treatment. Most witnesses do not deserve to be questioned in an obnoxiously aggressive manner. It is more effective for an advocate to be persistent and politely assertive. Unless a witness deserves to be treated differently, the fact finder likely expects counsel to be respectful towards the witness.

2.07.6 Enhance the Self-Interest of the Witness

Questions may be asked that make the witness look good. Witnesses are much more likely to agree with a position that serves their self-interest. If an employee is reluctant to admit to being tired at the end of a workday, the witness will be more likely to agree if that concession is enhanced by establishing the witness worked a long day, was quite productive, and is a dedicated and hard-working employee.

2.07.7 Establish Concepts with the Witness

To provide the fact finder with a different perspective and explanation of a situation, questions can establish facts with which the witness will agree, rather than trying to force an answer using specific words. A witness may balk at saying it was very dark out, but will agree that there was not much light and the witness could only see about fifty feet ahead.

2.07.8 Employ Indirection

With indirect questions the witness does not perceive why a question is being asked or the purpose of the line of questioning until the point is made. The impact of the answers to these veiled questions can be explained in final argument.

2.07.9 Do Not Exaggerate or Embellish

Focus on facts and foundational opinions. Use words that are based on the evidence. Do not overreach with overstated enquiries.

H. Controlling Responses

2.08 Managing the Cross

It is critical for the advocate to maintain control of the examination and the witness. This can be accomplished through various techniques.

2.08.1 Know the Answers

The advocate needs to ask relevant questions to which the answer is already known. It’s necessary to know where the answers are preserved. The source typically is the deposition transcript of the witness, or a document, or a prior statement. Having those sources readily available for impeachment will make witnesses more likely to agree to factual assertions of what they know, what they said, or what they did.

2.08.2 Predict Favorable Responses

Not everything counsel wants to ask on cross may have been previously asked in a deposition or appears in a prior statement or document made by the witness. This absence requires the advocate to predict that the witness will agree to the answer contained in the leading question. The more accurate the prediction, the more likely the response will be agreeable. Answers should be sought which have a high degree of favorable predictability.

2.08.3 Listen and Observe

The advocate can follow up on incomplete, nonresponsive, and inconsistent answers with clarifying questions. Counsel need to listen carefully to responses to make sure the witness answered the questions. A witness who evades or attempts to avoid answering can be controlled.

2.08.4 Control the Witness

The most effective way to control witnesses is to ask questions to which they must agree. Short, fact-based, leading questions compel the witness to answer and agree. If the witness does not respond properly, the question can be repeated.

Additional ways to control the witness include:

 Continue to insist on an answer to the question

 Rephrase the question seeking the same answer

 Advise the witness to answer

 Seek an agreement from the witness to cooperate just like they did on direct

 Ask the judge, arbitrator, or hearing officer for assistance to compel an answer

2.08.5 Close Loopholes

To increase the chances a witness will agree with an important question, it may be necessary to ask a witness a series of preliminary foundation questions that prompt responsive answers. Counsel can anticipate why a witness may try to evade answering and ask questions that eliminate those opportunities. Before questioning a witness about a prior statement, the advocate can establish facts that the witness made the statement when events were fresh in their mind.

2.08.6 Avoid Asking One Question Too Many

Counsel should stop asking questions when the necessary evidence has been obtained, even if additional questions have been prepared. There may be no good reason to continue if the response is satisfactory.

2.08.7 Avoid Explanations

Questions that ask “why” or “how” permit a narrative response and invite disaster. The witness should not be permitted to clarify or explain. The advocate can explain the import of the response in summation.

2.08.8 Expand Points

A single question on a topic can be broken into a series of questions that emphasize the point and have more impact. Instead of asking one question (“You had a few drinks that night.”), three questions can be asked in a series: “You had one drink? Then another? And one more?”

2.08.9 Save Point for Final Argument

While it can be effective to ask questions that only become clear in closing argument, questions usually should be designed so that at the end of a series of questions the fact finder has an understanding of the point being made. Summation can be the opportunity to clarify the import of uncertain responses.

2.09 Maintaining Control

If or when the advocate starts to lose control of the examination, secure questions can be asked that produce favorable responses.

2.09.1 Repeat Supportive Direct Examination

Direct examination testimony that supports the cross-examiner’s case should be highlighted on cross-examination. Previous testimony that does not support the case should not be repeated.

2.09.2 Ask “Neutral” Cross-Examination Questions

Safe, neutral questions can re-establish control and direct the witness to answer “yes” or “no.” The witness may be inclined to comply as the questioning becomes seemingly easier.

2.09.3 Avoid the Unknown

Control may be slipping because the inquiry explores uncharted areas. This probe can become dangerous if the witness offers unfavorable answers. It can be difficult to rebound from such responses, and it’s best not to delve into unknown areas.

I. Designing Questions for

Specific Witnesses

2.10 Types of Witnesses

Certain types of witnesses may need to be asked carefully crafted questions to obtain sought-after responses. LLMs can suggest respectful, accessible phrasing and courtroom aids. They might also tailor easily comprehended questions without sacrificing legal precision.

2.10.1 Witnesses Who Need Assistance

Children and witnesses with communication issues require special assistance with both the formulation and delivery of questions and their responses.

2.10.2 Experienced Witnesses

Individuals who frequently testify and expert witnesses will need to be carefully questioned as they may attempt to be clever or evade answers.

2.10.3 Reputation Witnesses

This opportunity does not occur very often as few cases involve reputation witnesses. Questions can establish specific bad acts, prior misconduct, convictions, and other instances of misbehavior that contradict the reputation established on direct examination.

2.10.4 Evasive Witnesses

Continued questioning of an evasive witness using short, fact-based leading questions can re-gain control, help obtain a favorable response, and demonstrate the evasiveness and lack of credibility. Summation is the time to explain why the evasive witness should not be believed. If a witness evades, an LLM can generate myriad variants of the same question, allowing counsel to re-ask cleanly until locking in an answer.

J. Discrediting Cross-Examination Approaches

2.11 Exploiting Weaknesses

As previously explained, a primary goal of cross is to discredit the witness, the evidence, and the opponent’s positions. Cross-examination can be structured to demonstrate how a story is implausible, improbable, or impossible.

2.11.1 The Implausible Story

The story does not comport with common sense or common life experiences, making it appear incredible.

2.11.2 The Improbable Story

A witness’s version of a story is hard to believe when it is unlikely the story could have happened that way.

2.11.3 The Impossible Story

Some witnesses may sincerely believe what they remember even if was impossible for them to have perceived an event. Carefully crafted questions can establish the impossibility.

2.11.4 Establishing Inconsistencies Between Witnesses

Cross-examination can clarify or emphasize inconsistencies between conflicting stories. A witness may be asked if they agree or disagree with answers given by another witness. Usually, a witness cannot be asked if another witness is telling the truth, as that is the province of the fact finder.

K. Impeachment

2.12 Employing Impeachment Strategies

Impeachment is a tactic designed to reduce the credibility of the witness, a story, or another witness. See [FRE 106](https://www.westlaw.com/Document/N9D79AAB06D0311EEBC7FE6E14EBA5796/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N9D79AAB06D0311EEBC7FE6E14EBA5796/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0), 607. LLMs can script prior-inconsistent-statement foundations, including depositions and exhibits, and might track which inconsistencies merit flagging.

2.12.1 Using Material Issues to Impeach

Impeachment is most effective when important issues, significant facts, or impactful opinions reduce the credibility of the witness or story. If an issue is collateral, immaterial, or insignificant the impeachment is usually ineffective or disallowed. Impeachment should be reserved for major points and not minor points, unless there are several minor points that amount to a major point.

2.12.2 Proving Impeachment Through Extrinsic Evidence

A witness may occasionally deny the impeaching evidence, and the cross-examiner is usually permitted to introduce extrinsic evidence to establish the impeaching fact. An extrinsic source is any source of evidence (usually an exhibit or the testimony of another witness) other than the present witness.

2.12.3 Responding to Impeachment Evidence by the Direct Examiner

The direct examiner has a number of options in responding to impeachment evidence. The advocate can:

 Object to the attempted impeachment.

 Request that related statements from the previous source be contemporaneously introduced in an effort to reduce the impact of the impeachment.

 Reduce the impact of the impeaching evidence on direct or redirect examination by introducing contrary information.

 Rehabilitate an impeached witness with a prior consistent statement if it rebuts a charge of fabrication or improper motive or statement.

 Explain during summation the deficiencies of the attempted impeachment.

 GenAI can propose narrow redirect questions that cure the specific impeachment ground and might flag better repairs for summation.

L. Areas of Impeachment

2.13 Established Areas of Impeachment

There are several categories for impeachment grounds:

 Material Interest

 Lack of Competency

 Inadequate Foundation

 Weak Recollection

 Inconsistent Actions

 Criminal Record

 Instances of Untruthfulness

2.13.1 Interest, Bias, or Prejudice

Witnesses may have an interest, bias, or prejudice in a case that motivates them to testify in a predisposed way.

2.13.2 Competency Deficiencies

Cross-examination may establish that a witness has deficiencies in the four competency requirements—oath, perception, recollection, and communication.

2.13.3 Inadequate Observation/Lack of Perception

To reduce credibility, the ability of the witness to observe an event or to perceive a situation may be challenged.

2.13.4 Poor Recollection/Lack of Memory

Cross-examination can reveal reasons why the witness’s memory is lacking or unduly influenced.

2.13.5 Inconsistent Conduct

Cross can demonstrate that the actions of the witness contradict their testimony.

2.13.6 Impeachment by Criminal Record

A witness may be impeached by introducing their prior criminal conviction. See [FRE 609](https://www.westlaw.com/Document/N6B035290C0F511D8A8CA80DCF7582C6A/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N6B035290C0F511D8A8CA80DCF7582C6A/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0).

2.13.7 Impeachment by Specific Instances of Untruthfulness

Relevant evidence relating to the untruthfulness of a witness may be introduced against that person during the cross-examination of that witness. See [FRE 608(b)](https://www.westlaw.com/Document/N64BD2EB0C0F511D8A8CA80DCF7582C6A/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N64BD2EB0C0F511D8A8CA80DCF7582C6A/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0).

2.13.8 LLMs, the Internet, and Impeachment

GenAI, when paired with vetted online sources and legal databases, can surface impeachment angles—biased relationships, prior inconsistent statements, adverse social-media posts, unfavorable public records—that might otherwise go unnoticed. LLMs can cross-check dates, locations, and narratives across large corpora, spot contradictions, and draft impeachment questions while flagging impeachment and foundation issues. Because digital trails persist even when a witness forgets, GenAI can locate and organize those materials. Of course, before relying on any of the above, counsel must always validate accuracy, authenticity, and admissibility.

M. Impeachment Strategies and Tactics

2.14 Impeachment by Prior Inconsistent Statements

The credibility of a witness may be diminished on cross-examination if prior statements made by the witness are inconsistent or contradictory. A witness can only be impeached with a prior statement that witness made, not with a statement made by another witness. See [FRE 613](https://www.westlaw.com/Document/N0490BAC08D6211EFB96292A2D3FA2FFC/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N0490BAC08D6211EFB96292A2D3FA2FFC/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0).

2.14.1 Impeachment Procedure

There are several major steps:

1. Reaffirm the direct examination testimony.

2. Describe the circumstances of the prior inconsistent statement.

3. Introduce the prior inconsistent statement.

4. Obtain the witness’s response to the inconsistent statement.

2.14.2 Reaffirming Direct Testimony

The witness is committed to the direct testimony by being asked questions that contain and repeat the earlier testimony. Precise questions prevent the witness from claiming confusion about the prior direct testimony when confronted with impeaching evidence.

2.14.3 Describing Circumstances

Although not required as a prerequisite to impeachment, the circumstances under which a prior statement was made help the fact finder understand the background and prevents a witness from explaining away the contrary evidence. The procedures used (given under oath) and persons present (their lawyer) when the witness testified at a deposition can be established.

2.14.4 Introducing Statement

The impeaching statement is read by the advocate or shown to the witness, who reads the statement aloud.

2.14.5 Obtaining the Witness’s Response

When the witness admits to making the prior statement, the impeachment is concluded. If the witness denies it, the statement can be introduced as an exhibit through the witness or by extrinsic evidence. For example, a person who heard and recorded the statement may be proffered to authenticate the statement. If a deposition is the source, that portion of the deposition transcript can be introduced into evidence.

2.14.6 Asking Impactive Follow-up Questions

Counsel may emphasize the impact of the impeachment by asking leading questions that highlight the mistakes or errors made by the witness.

2.14.7 Significant Prior Inconsistent Statement

Only significant, material discrepancies should be the basis for impeachment, unless there is a pattern or a significant number of minor inaccuracies amount to a loss of credibility, as described previously.

2.14.8 Introducing Contemporaneous Prior Statements

The direct examiner can request that additional portions of the prior statement be introduced contemporaneously with the impeaching part of the statement to prevent a cross-examiner from introducing selected facts out of context.

N. Types of IMPEACHMENT

2.15 Categories of Prior Inconsistent Statements

There are five major kinds of inconsistent statements:

 Prior Oath Statements

 Documents

 Composed Statements

 Verbal Statements

 Omissions

2.15.1 Prior Statements Under Oath (Oral Testimony)

These statements include testimony provided at depositions, administrative hearings, previous trials, motion hearings, preliminary hearings, and other proceedings.

2.15.2 Prior Documentary Statements Under Oath

Prior and consistent statements may appear in answers to interrogatories, the responses to requests for admissions, a verified complaint, or other documents signed by the witness under oath.

2.15.3 Written or Electronic Statements

Written statements include writings that have been signed, agreed to, or approved by a party. Examples include written statements given to a police officer or investigator, handwritten notes composed by the witness, typed statements signed by the witness, affidavits and court documents, business records, emails from the witness, electronic verified documents, and other authentic witness statements.

2.15.4 Oral Statements

Any oral statement a witness has made to anyone may be used as a source during impeachment.

2.15.5 Omissions

A common method of impeachment involves the cross-examination of a witness regarding a matter testified to under direct examination that does not appear in a prior written or oral statement. The omission is significant because there is no record of this material statement made prior to the direct examination testimony, and it will appear to be unsupported or fabricated.

Expert Examination

A. Experts

3.01 When to Use an Expert

An expert should be used when the scientific, technical, or other specialized knowledge of the expert will assist the fact finder in understanding the evidence or in determining a fact that is in issue.

3.01.1 Purposes of Expert Testimony

Expert testimony may provide a fact finder with factual information, opinions based on expert knowledge, explanations regarding scientific principles and theories, testimony regarding test procedures and results, interpretations of the facts and real evidence, the amount of recoverable damages, and an opinion that contradicts the opposition’s expert.

3.01.2 Who Is an Expert?

A person who has specialized and pertinent knowledge gained by education, training, experience, or skill may be qualified as an expert.

3.01.3 Areas of Expertise

The general test that most jurisdictions apply to determine expertise is whether the area of expertise has gained general acceptance within the relevant scientific, technical, or other specialized expert community, or has been otherwise recognized as a subject of expert information.

3.01.4 Preparation for Expert Testimony

The advocate should know the subject on which the expert will testify as well or better than the expert. Without this specialized information, the advocate may miss critical information or be unprepared to conduct a direct or cross-examination.

An LLM that contains some of the expert’s prior reports, depositions, and transcripts may potentially surface prior inconsistent or contradictory statements. GenAI can also help map the expert’s shifts in methodology or confidence across matters, generate side-by-side comparison tables, and draft tight impeachment or rehabilitation questions. Models can also propose foundational questions and demonstratives that highlight how that expert’s testimony might have changed, and why that matters (or doesn’t matter).

B. Direct Examination of Experts

3.02 Qualifying the Expert

The rules of evidence require that the expert must be qualified in the area about which the person will testify. See [FRE 702](https://www.westlaw.com/Document/N000E29606D0B11EE8985FABF62AE15E3/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N000E29606D0B11EE8985FABF62AE15E3/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0). The judge, arbitrator, or hearing officer are the gate keepers and determine whether an expert is “competent” based on the expert’s education, training, and experience. The expert may only testify in those areas based on the qualifications.

3.02.1 Establishing Qualifications

Qualifications may be presented in sequence at the beginning of the examination or may be introduced periodically throughout the testimony when relevant to support an opinion or conclusion. An effort should be made to “humanize” the expert by presenting their expertise in an interesting and non-bragging fashion. LLMs can compress CVs into tailored qualifications and propose questions and responses that might humanize expertise without bragging.

Common areas of qualifications are:

 Personal background

 How and when expert became involved in case

 Occupation

 Education and training

 Professional organizations

 Professional achievements

 Writings/publications

 Trial/hearing experience

 Specialized experience

 Firsthand knowledge about case

 Specific examination or tests conducted

 Fees for time spent as an expert in case

3.02.2 Alternative Approaches to Qualifications

Alternative ways to qualify an expert include submission of the expert’s resume or stipulations to the qualifications of the expert by opposing counsel.

3.02.3 Expert Opinions

An expert’s testimony will usually include a number of opinions, and an expert needs to testify about the sources of information supporting an opinion, the opinion itself, and the bases of the opinion. The advocate in some jurisdictions may need to use specific words as a predicate to the introduction of an opinion such as: “Do you have an opinion to a reasonable degree of certainty?” GenAI can flag potential evidentiary issues, scaffold opinions—subject, theory, sources, methods, results, opinions, bases—and might prepare hypotheticals that mirror admissible facts.

3.02.4 Outline of Expert Opinion

A summary outline includes:

 Subject matter of opinion

 Theories or supportive principles

 Sources of information

 Exhibits that support testimony

 Standard tests or procedures

 Specific tests or procedures

 Opinion(s)

 Bases of opinion(s)

 Explanation of opinion(s) and conclusion(s)

 Compensation for time spent on case

C. Sources of Information

3.03 Bases of Information

Sources of information are critical to support the expert opinion, including:

 Firsthand information

 Information obtained from other experts, documents, records, files, and individuals (see [FRE 703](https://www.westlaw.com/Document/N105A63D0B96E11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N105A63D0B96E11D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0))

 Evidence, including testimony heard or told to the expert during the instant proceeding

 If necessary, hypothetical questions

3.03.1 Personal, Firsthand Information

The foundation for this knowledge requires the expert to testify about where, when, and how the observations were made followed by a description of the observations.

3.03.2 Information Obtained from Other Sources

An expert may rely on information from other sources as long as it is the type relied upon by other experts in the same area to reach conclusions. Commonly, this information consists of discovery documents and deposition testimony.

3.03.3 Information Obtained at the Proceeding

The testimony of lay witnesses and other experts can provide the basis for an expert opinion.

3.03.4 Hypothetical Questions

Hypothetical questions are not required, but can be used if the expert has not been able to otherwise review the facts of a case. The direct examiner asks the witness the hypothetical question, which contains facts that have been or will be introduced during the proceeding. The expert is asked to form an opinion based on the hypothetical question. Hypothetical questions should be prepared in advance with the assistance of the expert, and they should be read as prepared to avoid mistakes.

D. Questioning Techniques

3.04 Question Formation

The form of questions for experts parallels questions for lay witnesses, as well as a few enhanced methods.

3.04.1 Employing Narrative Questions and Responses

The direct examiner usually wants an expert to answer narrative questions with explanatory responses. Reasonable latitude is allowed permitting experts to provide narrative answers. A mix of short and long answers is helpful to maintain the fact finder’s interest as well as effectively educate the fact finder. The expert acts like a teacher explaining circumstances and opinions to the fact finder.

3.04.2 Explaining Technical Terms

The direct examiner must understand and know how to pronounce all of the expert’s technical terms and then have the expert explain those terms and concepts in plain language that is understandable to a layperson. If testing is involved, the expert must explain why the testing was done and why the result is valid.

3.04.3 Using Treatises

A treatise, book, periodical, pamphlet, or website may be used on direct and cross-examination. The authenticity of a treatise may be established by a reliable authority, through the admission of a witness, through another verifying expert, or through judicial notice. The treatise information can be admitted as substantive evidence, or impeachment evidence, or both. LLM-backed tools with access to the internet can identify reliable authorities and might propose qualified admissions.

E. Cross-Examination of Experts

3.05 Preparing for Cross-Examination

In cross-examining an expert, the advocate must gather information about the expert’s identity, qualifications, opinions, bases for opinions, data and documents supporting opinions, information relied on in forming opinions, publications, previous trial or deposition experience as an expert, former times testifying on behalf of a plaintiff or defendant, and fees. The cross-examiner must become knowledgeable in the area by studying authorities, relying on websites, and consulting other experts. AI-backed tools can assemble many cross-examination questions from disclosures and discovery, generate live summaries, and might deliver citations for instant impeachment.

Issues that need to be addressed include:

 What type of expert is involved in the case?

 Is the expert report available?

 What were the results from the expert’s deposition?

 What are the expert’s qualifications?

 What are the expert’s sources of information?

 Are they ordinarily relied on?

 Is the information relied on admissible?

 What are the expert’s opinions?

 Are they consistent with others?

 Can differences be reconciled?

 What are bases for the opinions?

 What exhibits need be introduced?

 What visual aids will be helpful?

 What writings has the expert authored that will be useful?

 What are areas of impeachment?

 What treatises contradict the expert?

3.06 Cross-Examination Areas

The cross-examination approaches and techniques that apply to lay witnesses also apply to experts. Other tactics that can be used to cross-examine experts include the following supportive and discrediting approaches.

• Agreement/Disagreement
• Obtaining Concessions. An opposing expert may be used to establish, agree with, or corroborate positions and opinions of the supporting experts.
• Criticizing the Other Side’s Position. The opposing expert may also be used to criticize the opposing party’s position, statements, or conduct.
• GenAI can help mine the expert’s concessions—areas of overlap with another expert—and might script short, safe leading questions.
• Interests
• Expert Fees and Financial Interests. If the expert receives an excessive amount of money for their time and involvement, the amount of the fee can be established.
• Bias or Prejudice. An expert may have developed a bias because of work in similar cases or because the expert is involved regularly with one side or has done previous work for the client or advocate.
• Insufficient Expertise
• Deficient or Inappropriate Expertise. Some opposing experts may be vulnerable to attacks on their lack of education, training, experience, or skills in an area of involved in the case.
• Subjective Opinions. An expert may admit that the opinion the expert reached is a matter of judgment and not based on immutable principles.
• Inadequate Information
• Inadequate Sources of Information. Questions may reveal that an expert relied on incomplete or inadequate sources.
• Unreliable or Insufficient Information. Some experts may base an opinion on subjective facts obtained from a party or other information that is not reliable because of its source or content.
• Other Facts/Exhibits
• Disputed Facts. Some of the facts that form the basis for the expert opinion may be disputed. If the facts change, the opinion should change.
• Using Exhibits. Case exhibits may contain information that contradicts or differs from the expert’s testimony. Sources include electronic and printed documents, emails, and paper materials.
• Deficient Work
• Lack of Thoroughness. Questions can be asked that show how little an expert has done and how much more an expert could have done.
• Insufficient Testing. An expert may not have conducted sufficient tests or followed adequate procedures to support an opinion.
• Other Causes/Experts
• Existence of Other Causes. Often, there are alternative explanations for something that happened other than that explained by the expert on direct examination. Cross-examination can demonstrate these other possible causes and diminish the credibility of the expert’s opinion.
• Differences of Opinion Among Experts. Opinions in some areas are subject to significant and legitimate differences of opinion among qualified experts. This is especially true in subjective or interpretive fields.
• Impeachment
• Inconsistent Prior Statements. An expert witness can be cross-examined using any oral or written statement by that expert that is inconsistent with the opinion given at trial.
• Treatises. Treatises can be used to impeach the expert as well as for other purposes. See [FRE 803(18)](https://www.westlaw.com/Document/N04E853C0B97011D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0" \o “https://www.westlaw.com/Document/N04E853C0B97011D8983DF34406B5929B/View/FullText.html?transitionType=Default&contextData=(sc.Default)&VR=3.0&RS=da3.0).
• Other Deficiencies
• Hypothetical Questions. If a hypothetical is used in direct examination, an effective way to cross-examine is to ask the expert concise hypothetical questions that contain facts different from the direct examination hypothetical and that result in differing opinions.
• LLMs can draft “delta” hypotheticals that change only one fact at a time—and might ladder those changes in escalating steps, forcing the expert to mark where the opinion flips and why. GenAI can also script admissibility-safe hypotheticals that anchor each assumed fact.
• Safely Exposing Deficiencies. If questions suggested in the previous subsections are too risky, “safe” questions can be asked that address the limited amount of time the expert spent reviewing the information, the fact that the information the expert relied on has been provided by the party who retained the expert, and the facts and information on which the expert relied are not the facts on which other testifying experts in the trial relied.
• LLMs can pose concise, control-preserving hypotheticals (e.g., “Assume a 30-minute review limited to party-provided records: does that change your confidence level or error rate?”). GenAI can also generate parallel hypotheticals that swap in expert-accepted datasets or methodologies, prompting the expert to explain why the original assumptions still support the same conclusion.
• Lack of Reliability of the Field of Expertise. If the cross-examiner does not present an expert in the so-called “field of expertise” presented by the opposing party’s expert, the cross-examiner may use cross to establish the unreliability of the “field of expertise” and the failure of experts in the broader area of study to accept the reliability of the posited field.
