California Code of Civil Procedure
(a) The protection of information from discovery on the ground that it is privileged or that it is a protected work product under Chapter 4 (commencing with Section 2018.010) is waived unless a specific objection to its disclosure is timely made during the deposition.
(b) Errors and irregularities of any kind occurring at the oral examination that might be cured if promptly presented are waived unless a specific objection to them is timely made during the deposition. These errors and irregularities include, but are not limited to, those relating to the manner of taking the deposition, to the oath or affirmation administered, to the conduct of a
party, attorney, deponent, or deposition officer, or to the form of any
question or answer. Unless the objecting party demands that the taking of the deposition be suspended to permit a motion for a protective order under Sections 2025.420 and 2025.470, the deposition shall proceed subject to the objection.
(c) Objections to the competency of the deponent, or to the relevancy, materiality, or admissibility at trial of the testimony or of the materials produced are unnecessary and are not waived by failure to make them before or during the deposition.
(d) If a deponent objects to the production of electronically stored information on the grounds that it is from a source that is not reasonably accessible because of undue burden or expense and that the deponent will not search the source in the absence of an agreement with the deposing
party or court order, the deponent
shall identify in its objection the types or categories of sources of electronically stored information that it asserts are not reasonably accessible. By objecting and identifying information of a type or category of source or sources that are not reasonably accessible, the deponent preserves any objections it may have relating to that electronically stored information.
(e) If a deponent fails to answer any question or to produce any document, electronically stored information, or tangible thing under the deponent’s control that is specified in the deposition notice or a deposition subpoena, the party seeking that answer or production may adjourn the deposition or complete the examination on other matters without waiving the right at a later time to move for an order compelling that answer or production under Section 2025.480.
(f) Notwithstanding subdivision (a), if a deponent notifies the party that took a deposition that electronically stored information produced pursuant to the deposition notice or subpoena is subject to a claim of privilege or of protection as attorney work product, as described in Section 2031.285, the provisions of Section 2031.285 shall apply.
