For nearly a decade, Federal Rule of Evidence 502(d) has provided a straightforward procedure for litigants to safeguard privileged information against waiver by inadvertent disclosure. Properly drafted Rule 502(d) orders eliminate the need for a party claiming the privilege to show that a disclosure of information protected by the lawyer-client privilege or work product doctrine was “inadvertent” as a matter of law. Instead, the party simply demands that adversaries return or destroy the mistakenly produced materials.
