California Code Of Civil Procedure Section 2031.310

(a) On receipt of a response to an inspection demand, the party demanding an inspection may move for an order compelling further response to the demand if the demanding party deems that any of the following apply: (1) A statement of compliance with the demand is incomplete. (2) A representation of inability to comply is inadequate, incomplete, or evasive. (3) An objection in the response is without merit or too general. (b) A motion under subdivision (a) shall comply with both of the following: (1) The motion shall set forth specific facts showing good cause justifying the discovery sought by the inspection demand. (2) The motion shall be accompanied by a meet and confer declaration under Section 2016.040. (c) Unless notice of this motion is given within 45 days of the service of the response, or any supplemental response, or on or before any specific later date to which the demanding party and the responding party have agreed in writing, the demanding party waives any right to compel a further response to the inspection demand. (d) The court shall impose a monetary sanction under Chapter 7 (commencing with Section 2023.010) against any party, person, or attorney who unsuccessfully makes or opposes a motion to compel further response to an inspection demand, unless it finds that the one subject to the sanction acted with substantial justification or that other circumstances make the imposition of the sanction unjust. (e) If a party fails to obey an order compelling further response, the court may make those orders that are just, including the imposition of an issue sanction, an evidence sanction, or a terminating sanction under Chapter 7 (commencing with Section 2023.010). In lieu of or in addition to that sanction, the court may impose a monetary sanction under Chapter 7 (commencing with Section 2023.010).
