ABA Formal Opinion 508: The Ethics of Witness Preparation
ABA Formal Opinion 508 (2023) is the most comprehensive treatment of witness preparation ethics since the attorney's role in preparing witnesses has been questioned in high-profile trial controversies. The opinion distinguishes permissible witness preparation — reviewing documents, refreshing recollection, explaining legal procedures, discussing anticipated questions — from impermissible coaching — suggesting false testimony, fabricating documents, or instructing witnesses to withhold truthful information. For AI-assisted deposition preparation, the ethics question focuses on whether AI-generated question lists or preparation protocols improperly cross into coaching by creating overly scripted or evasive testimony patterns.
Document Volume in Complex Litigation: The Preparation Challenge
Modern litigation involves document productions measured in millions of pages. Preparing a witness for deposition in complex commercial litigation requires identifying all documents authored by or mentioning the witness — potentially thousands of documents — reviewing them for topics the examining attorney may raise, and preparing the witness to address each topic accurately. This review process, done manually, takes 40-80 attorney hours per witness in complex cases. AI-powered document review reduces this to 2-4 hours — identifying all witness-related documents, organizing them by topic, and generating a preparation outline.
Video Deposition Transcript Accuracy and Impeachment Planning
Modern depositions are video-recorded, with real-time or post-event transcript generation by court reporters or AI transcription services. AI transcription accuracy for standard English deposition recordings exceeds 95% in controlled environments. Transcript accuracy issues arise most frequently with technical terms, proper nouns, and accented speech — areas where AI transcription errors can create misleading impeachment opportunities if not corrected. AI-assisted impeachment planning — identifying prior inconsistent statements across thousands of pages of deposition and trial transcripts — transforms the preparation process for examination of adverse witnesses.
