Effective as of January 1, 2020, all civil litigants in California will have additional discovery burdens. The California Code of Civil Procedure now requires “[a]ny documents or category of documents produced in response to a demand for inspection, copying, testing, or sampling shall be identified with the specific request number to which the documents respond.” Cal. Civ. Pro. § 2031.280(a). This is a major departure from the prior rule. Responsive documents can no longer be produced as they were “kept in the usual course of business.” This new requirement applies to all pending cases in California, regardless of whether a case commenced prior to the amendment’s effective date of January 1, 2020.
