Privilege review
Privilege review is the check that no legally privileged document is handed to the other side during disclosure.
A privileged document produced by mistake can be unrecoverable. That risk is why review is slow and why it stays a human judgement rather than an automated one.
Tools help by narrowing the pile: flagging correspondence with counsel, grouping by sender, surfacing near-duplicates so one decision covers a family of documents. The decision itself stays with a lawyer.
