It has been held that the "new class of actions and proceedings” to which article VI, § 7 (b) specifically refers are those which were unknown at common law and therefore would otherwise be outside the general jurisdiction continued and preserved by section 7 (a) (Matter of Seitz v Drogheo, 21 NY2d 181; Kagen v Kagen, 21 NY2d 532, 536-537, supra). However, it has never been suggested that every claim or dispute arising under a legislatively created scheme may be brought to the Supreme Court for original adjudication. To the contrary, in Loretto v Teleprompter Manhattan CATV Corp. (58 NY2d 143, 152-153), this Court observed that concurrent original jurisdiction is not necessarily conferred on the Supreme Court when the Legislature provides for the adjudication of regulatory disputes by an administrative agency within the executive branch, as distinguished from a court within the judicial branch. Indeed, we stated in Loretto that there is nothing in article VI, § 7 (b) or the relevant case law "to suggest that administrative agencies cannot be given a first instance adjudicatory function, subject to judicial review” (58 NY2d, at 153, supra; cf., Flacke v Onondaga Landfill Sys., 69 NY2d 355, 362-363 [Supreme Court does not have jurisdiction concurrent with that of Department of Environmental Conservation with respect to agency’s legislative licensing and regulatory functions]).
