grams after conviction, rather than before conviction as in the case of diversion. Our decision in Esteybar teaches that the issue whether a power is judicial in nature depends not on the procedural posture of the case but on the substance of the power and the effect of its exercise. Here the Legislature’s choice of pre-conviction rather than post-conviction intervention is easily understandable in the light of its dual purpose of sparing appropriately selected first offenders the stigma of a criminal judgment and avoiding the delays and costs of unnecessary trials. At whatever stage such intervention occurs, however, it is an integral step in the process leading to the disposition of the case before the court, and therefore constitutes an exercise of judicial authority within the meaning of the constitutional doctrine of separation of powers.
At oral argument the People urged for the first time the contention that even if the offending provision of Penal Code section 1000.2 is invalid it is not severable from the remainder of the statute. It has long been deemed improper to raise new points at oral argument, and such questions will ordinarily not be considered. (Lotts v. Board of Bark Commrs. (1936) 13 Cal.App.2d 625, 636 [57 P.2d 215]; Johns v. Baender (1919) 40 Cal.App. 790, 793 [182 P. 55].) In any event, we resolved essentially the same issue adversely to the People in People v. Navarro (1972) supra, 7 Cal.3d 248, 260-265.
We conclude that the provision of Penal Code section 1000.2 requiring the consent of the prosecutor before a trial court may order that a qualified defendant be diverted into a program of education, treatment, or rehabilitation, violates article III, section 3, of the California Constitution.
The alternative writ is discharged and the peremptory writ is denied.

I dissent. Regretfully, if the concurrence requirement is unconstitutional, the entire statute must fall.
The majority dismisses the severability issue with the comment that “essentially the same issue” was resolved in
