In a writ of mandate from a Los Angeles Superior Court case, the court clarified that a Code of Civil Procedure §2031.210, a statement of compliance (the written response) for a document demand does NOT to identify the specific request and document to which each document will pertain. Nor does the document response portion need to be verified. (The Response needs to be verified unless is all objections.) See http://sos.metnews.com/sos.cgi?0823//B321229
The responding party only needs to identify the demand category (e.g., Demand No. 2, 3) as it pertains to the documents being produced, e.g., by Bates number.
