ANSWER: A fictional document. A non-existent objection neither based in statutory authority nor found in case law. A statement by a party during the discovery phase that they will neither be held to the Code of Civil Procedure nor the rules of evidence.
In my years as a discovery referee, I have found that lawyers have gotten into the bad habit of inserting a preamble in their responses to interrogatories, requests for production and requests for admissions. These preambles often state the obvious as to what their rights are as responding parties. However, many times these preambles state general objections to the entirety of the propounded discovery and insert rights that are contrary to the obligations of the Discovery Act, the evidence code and current case law. Even though several interrogatories, requests for documents and request for admissions may be objectionable on the same ground they may not be objected to as a group. See Hogan and Weber, California Civil Discovery (2d. ed 2009) §51
