(1) After a judgment imposing a punishment other than imprisonment in the state prison.
(2) When the court, upon committing the defendant to the Youth Authority, designates the offense to be a misdemeanor.
(3) When the court grants probation to a defendant without imposition of sentence and at the time of granting probation, or on application of the defendant or probation officer thereafter, the court declares the offense to be a misdemeanor.
(4) When the prosecuting attorney files in a court having jurisdiction over misdemeanor offenses a complaint specifying that the offense is a misdemeanor, unless the defendant at the time of his or her arraignment or plea objects to the offense being made a misdemeanor, in which event the complaint shall be amended to charge the felony and the case shall proceed on the felony complaint.
(5) When, at or before the preliminary examination or prior to filing an order pursuant to Section 872, the magistrate determines that the offense is a misdemeanor, in which event the case shall proceed as if the defendant had been arraigned on a misdemeanor complaint.
(c) When a defendant is committed to the Youth Authority for a crime punishable, in the discretion of the court, by imprisonment in the state prison or by fine or imprisonment in the county jail, the offense shall, upon the discharge of the defendant from the Youth Authority, thereafter be deemed a misdemeanor for all purposes.
(d) A violation of any code section listed in Section 19.8 is an infraction subject to the procedures described in Sections 19.6 and 19.7 when:

(2) The court, with the consent of the defendant, determines that the offense is an infraction in which event the case shall proceed as if the defendant had been arraigned on an infraction complaint.
