Whether filter-team procedures like the ones in this case are invalid because they undermine the attorney-client-privilege

QUESTION PRESENTED The court of appeals allowed a Department of Justice “filter team” consisting of government attorneys not conducting the investigation to review assertedly privileged materials of petitioners’ lawyers, seized during a search, before any court ruled on petitioners’ assertions of attorney-client privilege and work-product protection—and without requiring any showing that an exception to privilege may apply. The question presented is: Whether filter-team procedures like the ones in this case are invalid because they undermine the attorney-client privilege and work-product protection.
