Congress enacted FRE 502 to provide a more workable framework to evaluate when waiver occurs in the event of inadvertent production than that set out by FRCP 26(b)(5) in 2006.
Section 502(a) discusses the scope of waiver and restricts any waiver to the disclosed communication (instead of other undisclosed communications) unless the waiver is intentional, the same subject matter is at issue, and they should be considered together.
Section 502(b) creates an analysis for waiver based on inadvertent disclosure -- the disclosure must be inadvertent, the producing party took reasonable steps to prevent disclosure, and followed the process in 26(b)(5)(B) to recover the privileged material (which means asking for it back, and/or having the court make a determination). This section essentially eliminates sections FRCP 26(b)(5)(A)(i) and 26(b)(5)(A)(ii).
Section 502(c) maintains federal law as the floor for waiver in federal cases. Under that section, if a party inadvertently produces privileged material in a state case, it's not a waiver in federal court if 1) it wasn't a waiver in the state where you disclosed it, and 2) federal law would not allow a waiver under the same circumstances.
Section 502(d) allows the parties to have the judge issue an order that inadvertent production is not a waiver for the case -- meaning, by virtue of FRE 502(c), that it is not a waiver for any other federal or state case.
Section 502(e) contrasts with 502(d) as to the power of agreement between the parties and not with the court: An agreement under section (e) between the parties that disclosure does not lead to waiver is only binding on the parties and does not have the same effect as a court order under section 502(d).
Section 502(f) says that the provisions of FRE 502 apply to both federal and state proceedings, even where state law applies to the merits.
Counsel addressing issues of waiver and inadvertent disclosure should also carefully review the committee notes on the intent of the rule to always lean towards maintaining the privilege.
