Order and judgment affirmed, without costs or disbursements.
The petitioner, the Rockland County Commissioner of Social Services (hereinafter the Rockland commissioner) asserts that he has standing to seek review of a determination of the State commissioner pursuant to Social Services Law § 22 (9) (b). Social Services Law § 22 (9) (b) was amended to empower a local social services official aggrieved by a determination of the State commissioner after a fair hearing to apply for review pursuant to CPLR article 78 unless otherwise precluded by Federal Law (see, L 1978, ch 473, § 2). Federal statutory law requires that the medical assistance program at issue here must be administered by a single State agency (see, 42 U.S.C. § 1396a [a] [5]), and the applicable Federal regulations provide that a local agency must not have authority to review, change or disapprove the decision of the single State agency (see, 42 C.F.R. § 431.10 [b] [1], [2] [ii]; [e] [3]). Hence, the mandate of Federal law precludes the instant challenge by the Rockland commissioner, or the political subdivision which he represents (see, Matter of Beaudoin v. Toia [Jorczak], 45 N.Y.2d 343; Matter of Romano v. Perales, 110 A.D.2d 1028, affd 67 N.Y.2d 848 for reasons stated in the mem at App. Div.). Lazer, J.P., Gibbons, Niehoff and Kunzeman, JJ., concur.
