Categorical Privilege Logs Are Not Disfavored

Why It Matters

The ruling streamlines privilege assertion, reducing litigation costs and encouraging efficient discovery practices across federal courts.

Key Takeaways

• Categorical privilege logs allowed under Fed. R. Civ. P. 26(b)(5)(A)(ii)
• Court rejected need for court order to use categorical logs
• Logs avoid burdensome document‑by‑document privilege review
• Ninth Circuit precedent misread; categorical logs not disfavored
• Parties must still provide sufficient detail for privilege assessment

Pulse Analysis

The recent Thompson decision underscores a shift toward proportionality in electronic discovery. While Rule 26(b)(5)(A)(ii) requires a privilege log that enables the opposing party to assess claims, the court affirmed that a categorical format satisfies this obligation when a document‑by‑document approach would be excessively burdensome. By referencing the Advisory Committee Notes, the judge highlighted that the rule’s intent is to balance transparency with practicality, allowing parties to group similar privileged materials without sacrificing essential information.

Practitioners should view this ruling as a green light for adopting categorical logs in complex, high‑volume cases. The court’s analysis focused on the sheer scale of the request—over four years of client matters for roughly 19 attorneys—and concluded that sorting each document individually would be “unmeasurable.” By permitting a higher‑level categorization, firms can allocate resources to substantive review rather than mechanical sifting, ultimately accelerating case timelines and curbing discovery expenses.

Looking ahead, the decision may influence other districts to follow suit, especially as courts grapple with the growing volume of electronically stored information. Legal teams should ensure their logs contain enough detail—such as privilege type, document category, and a brief description—to meet the adequacy standard while still leveraging the efficiency of categorical grouping. Embracing this approach can also mitigate disputes over privilege, fostering a more collaborative discovery environment and preserving judicial resources.
