President Bush signed new Federal Rule of Evidence 502, S. 2450, into law on September 19, 2008. The rule applies to the inadvertent disclosure in discovery of information protected by the attorney-client privilege and work-product doctrine. Check out the very good Federal Evidence Blog for the text of the rule, analysis and links, including this one to Statement of Congressional Intent Regarding Rule 502 of the Federal Rules of Evidence (154 Cong. Rec. H7818-H7819 (Sept. 8, 2008)).
