A document is labeled "attorney-client privilege confidential".
If said document is disclosed by the records custodian providing a box of records to the plaintiff, is the document "fair game" for the plaintiff to cite in any future context (including litigation)? Are there any exceptions when it would not be "fair game" ?
Does saying "Ooops! I did not mean to disclose this" restore AC-Privilege?
Update: Assume the document is photocopied from a set of boxed corporate records and that a documented records request was issued.
