Protect Privileged Documents 
New Strategies to 



From Inadvertent Disclosure







ceeding “if the holder took reasonable steps 
to prevent disclosure and also promptly took 
reasonable steps to rectify the error.”6 Thus 
Rule 502(b) protects against waiver associ- 
ated with inadvertent disclosures so long as 
parties seek to prevent accidental disclosures 
by using reasonable pre-production measures 
and react promptly post-production to assert 

and preserve privilege. That “middle ground” 
essentially codified the approach of the major- 
ity of federal courts within New York state, 
as well as the approach taken by New York 
state courts.
While subsections (a) and (b) operate as 
the default rules that apply to discovery dis- 
closures when parties have not made other 
arrangements to address such waiver issues, 

subsection (d) allows parties to request an 
order from the court preventing waiver of 
privilege as a result of disclosures without 
regard to the reasonableness of the measures 
taken during the pre-production review or 
the promptness of post-production action. 
Rule 502(d) permits a federal court to order 
that the disclosure of privileged or protected 
communications or information does not 

waive those protections in the pending case 
or in any other federal or state proceeding. 
Importantly, the application of Rule 502(d) 
does not depend on whether the disclosure 
was inadvertent although parties can draft 
a Rule 502(d) order to limit the scope of 
protection only to inadvertently produced 
documents if they so choose. The court order 

may also provide for “claw-back” and “quick 
peek” arrangements “as a way to avoid the 
excessive costs of pre-production review for 
privilege and work product.”7 Notably, Peck 
has observed that “[t]here is no legitimate OCK
basis for a party (even with little ESI itself) GST
to object to a Rule 502(d) order, in any event, BI
the Court can enter a Rule 502(d) order over
