What is the scope of the Attorney General's prosecutorial authority?

We have held that the Attorney-General's prosecutorial authority is strictly limited to the specific statutory grants of such authority (see, Della Pietra v. State of New York, 71 N.Y.2d 792, 796-797, 530 N.Y.S.2d 510, 526 N.E.2d 1). Nonetheless, petitioners have failed to establish here that the Attorney-General or his staff have acted or threatened to act without or in excess of duly prescribed jurisdiction. Indeed, the essential deficiency in petitioners' proof is the absence of any evidence that the Attorney-General was purporting to exercise the prosecutorial authority of that office in the instant case.
