  (b) If the action is on a complaint charging a misdemeanor, counsel for the defendant may (1) demur, (2) move to dismiss the complaint on the ground that there is not reasonable cause to believe that a public offense has been committed and that the defendant is guilty thereof, or (3) make a motion under Section 1538.5.
  (c) If the proceeding involves an alleged violation of probation, mandatory supervision, postrelease community supervision, or parole, counsel for the defendant may move to reinstate supervision on the ground that there is not probable cause to believe that the defendant violated the terms of his or her supervision.
  (d) In ruling upon any demurrer or motion described in subdivision (a), (b), or (c), the court may hear any matter which is capable of fair determination without the personal participation of the defendant.
  (e) A demurrer or motion described in subdivision (a), (b), or (c) shall be made in the court having jurisdiction over the complaint. The defendant shall not be certified until the demurrer or motion has been decided.
