CA Civ Proc Code Section 2032.620

(a)

If the party at whose instance an examination was made fails to make a timely delivery of the reports demanded under Section 2032.610, the demanding party may move for an order compelling their delivery. This motion shall be accompanied by a meet and confer declaration under Section 2016.040.

(b)

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 delivery of medical reports under this section, 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.

(c)

If a party then fails to obey an order compelling delivery of demanded medical reports, 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 those sanctions, the court may impose a monetary sanction under Chapter 7 (commencing with Section 2023.010). The court shall exclude at trial the testimony of any examiner whose report has not been provided by a party.
