If a person withholds information based on privilege, what must they do?

When a person withholds information based on privilege, they are required to comply with the specific procedural requirements outlined in Rule 26(b)(6)(A), which necessitates providing a privilege log. This log serves to inform the other parties involved about the nature of the withheld information while maintaining the confidentiality afforded by the privilege. The privilege log typically includes details such as the date of the document, the type of document, the author, and the recipients, allowing the court and other parties to assess the validity of the claim of privilege without exposing the privileged information itself. This requirement helps to balance the interests of fair discovery with the protection of sensitive information that is covered under legal privileges.
