Section 2023.030.

To the extent authorized by the chapter governing any particular discovery method or any other provision of this title, the court, after notice to any affected party, person, or attorney, and after opportunity for hearing, may impose the following sanctions against anyone engaging in conduct that is a misuse of the discovery process:

(a) The court may impose a monetary sanction ordering that one engaging in the misuse of the discovery process, or any attorney advising that conduct, or both pay the reasonable expenses, including attorney's fees, incurred by anyone as a result of that conduct. The court may also impose this sanction on one unsuccessfully asserting that another has engaged in the misuse of the discovery process, or on any attorney who advised that assertion, or on both. If a monetary sanction is authorized by any provision of this title, the court shall impose that sanction 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.

(b) The court may impose an issue sanction ordering that designated facts shall be taken as established in the action in accordance with the claim of the party adversely affected by the misuse of the discovery process. The court may also impose an issue sanction by an order prohibiting any party engaging in the misuse of the discovery process from supporting or opposing designated claims or defenses.

(c) The court may impose an evidence sanction by an order prohibiting any party engaging in the misuse of the discovery process from introducing designated matters in evidence.

(d) The court may impose a terminating sanction by one of the following orders:

(1) An order striking out the pleadings or parts of the pleadings of any party engaging in the misuse of the discovery process.

(2) An order staying further proceedings by that party until an order for discovery is obeyed.

(3) An order dismissing the action, or any part of the action, of that party.

(4) An order rendering a judgment by default against that party.

(e) The court may impose a contempt sanction by an order treating the misuse of the discovery process as a contempt of court.

(f) (1) Notwithstanding subdivision (a), or any other section of this title, absent exceptional circumstances, the court shall not impose sanctions on a party or any attorney of a party for failure to provide electronically stored information that has been lost, damaged, altered, or overwritten as the result of the routine, good faith operation of an electronic information system.

(2) This subdivision shall not be construed to alter any obligation to preserve discoverable information.
