Cal. Welfare and Institutions Code § 5226.1

If a judge issues an order for evaluation under conditions set forth in this article, proceedings on the criminal charge then pending in the court from which the order for evaluation issued shall be dismissed or suspended until such time as the evaluation of the defendant and the subsequent detention of the defendant for involuntary treatment, if any, are completed. Upon completion of such evaluation and detention, if any, the defendant shall, if such criminal charge has not been dismissed, be returned by the sheriff of the county in which the order of evaluation was made, from the evaluation or intensive treatment facility to the custody of the sheriff who shall return the defendant to the court where the order for evaluation was made, and proceedings on the criminal charge shall be resumed or dismissed. If, during evaluation or detention for involuntary treatment, the defendant is recommended for conservatorship, and if the criminal charge has not previously been dismissed, the defendant shall be returned by the sheriff to the court in which such charge is pending for the disposition of the criminal charge prior to the initiation of the conservatorship proceedings. The judge of such court may order such defendant to be detained in the evaluation or treatment facility until the day set for the resumption of the proceedings on the criminal charge.
