Common questions
Frequently Asked
4
Does the work product doctrine protect notes summarizing interviews with non-employee witnesses?+
Yes. Materials prepared by counsel in anticipation of litigation, such as notes reflecting interviews with potential witnesses, receive qualified protection even when the interviewees are not clients. Production requires a showing of substantial need and undue hardship.
Supporting sources
How does work product protection differ from attorney-client privilege?+
Work product protection is qualified and covers materials prepared in anticipation of litigation regardless of whether they involve client communications. Attorney-client privilege is absolute but limited to confidential communications between attorney and client for legal advice.
Supporting sources
What showing overcomes work product protection for factual material?+
The requesting party must demonstrate substantial need for the materials and inability to obtain substantially equivalent information without undue hardship. Mental impressions of counsel remain protected even when that showing is made.
Supporting sources
Does inadvertent production of work product waive protection?+
No, provided the disclosure was inadvertent, reasonable steps were taken to prevent disclosure, and prompt steps were taken to rectify the error. The producing party may still assert protection after notification.
