Cal. PEN § 1388

(a) In any case where an order for the dismissal of a felony action is made, as provided in this chapter, and where the defendant had been released on his own recognizance for that action, if the prosecutor files another accusatory pleading against the same defendant for the same offense, unless the defendant is present in court at the time of refiling, the district attorney shall send a letter to the defendant at his last known place of residence, and shall send a copy to the attorney of record, stating that the case has been refiled, and setting forth the date, time and place for rearraignment.

(b) If the defendant fails to appear for arraignment as stated, or at such time, date, and place as has been subsequently agreed to by defendant’s counsel and the district attorney, then the court shall issue and have delivered for execution a warrant for his arrest within 20 days after his failure to appear.

(c) If the defendant was released on his own recognizance on the original charge, he shall, if he appears as provided in subdivisions (a) and (b), be released on his own recognizance on the refiled charge unless it is shown that changed conditions require a different disposition, in which case bail shall be set at the discretion of the judge.
