Forbidden: Pressure to change truthful recollection. Suggest recollection is wrong because harmful. Coach to minimize or hide unfavorable facts.
Gray-Area Tests
- After document review, does witness have present recollection or only adoption of the document?
- Are you clarifying expression without changing substance?
- Are you explaining legal relevance without instructing how to answer?
- Would you be comfortable with the prep transcript before a disciplinary committee?
