Howington v. Taiwan Semiconductor Manufacturing Co., Ltd.

Howington · United States District Court for the Northern District of California · September 8, 2025 · No. 24-cv-05684-VKD

Summary

The United States District Court for the Northern District of California addresses a discovery dispute concerning plaintiffs’ claims of attorney-client privilege, work-product protection, and the common interest doctrine. The court finds that the record is insufficient to resolve the dispute and directs plaintiffs to amend their privilege log, while permitting further briefing or in camera review if disagreements remain. The court also orders the parties to propose a briefing schedule and states that no party may resist deposition discovery solely because the privilege dispute remains unresolved.

Holdings

  1. The court could not fully resolve the discovery dispute because plaintiffs had not supplied sufficient communication-specific information establishing the asserted privilege or protection and the privilege log did not clearly identify all disputed entries.
  2. Communications among jointly represented named plaintiffs may be privileged or protected even when counsel did not participate, but only if the communication was privileged or protected in the first instance and concerned the common representation or a common legal interest.
  3. Absent putative class members generally are not clients of class counsel merely because they may become members of a certified class; before certification, pre-certification communications with potential class members are generally not privileged unless plaintiffs establish a separate attorney-client relationship.
  4. A shared interest in the filing or outcome of litigation, without a demonstrated common legal interest and communication made to further that interest, is insufficient to invoke the common-interest doctrine.
  5. Disclosure of work product to a third party does not necessarily waive protection, but waiver occurs when disclosure is made to an adversary or in a manner that substantially increases the opportunity for potential adversaries to obtain the work product; plaintiffs did not make the required showing.
  6. The court did not order immediate in camera review; defendants could renew the request after further development of the record, or the parties could stipulate to submission of a representative sample.

Questions Presented

  1. Whether the record was sufficient to determine whether communications among named plaintiffs were protected by attorney-client privilege or work-product protection.
  2. Whether communications between named plaintiffs and absent putative class members were privileged or protected, or whether disclosure waived any protection.
  3. Whether plaintiffs established that the common-interest doctrine preserved privilege or protection for communications shared with absent class members or other non-parties.
  4. Whether the privilege log adequately described the withheld materials as required by Federal Rule of Civil Procedure 26(b)(5)(A).
  5. Whether defendants were entitled to immediate in camera review of the disputed communications.
