—[*1]Proceeding pursuant to CPLR article 78 (transferred to this Court by order of the Supreme Court, entered in Clinton County) to review a determination of respondent which found petitioner guilty of violating certain prison disciplinary rules.

Petitioner challenges a determination finding him guilty of violating certain prison disciplinary rules. The Attorney General has advised this Court by letter that the determination at issue has been administratively reversed and that all references thereto have been expunged from petitioner's institutional record. Inasmuch as petitioner has received all the relief to which he is entitled and is no longer aggrieved, the matter is dismissed as moot (see Matter of Barclay v State of N.Y. Dept. of Correctional Servs., 297 AD2d 870 [2002], lv denied 99 NY2d 504 [2002]).

Mercure, J.P., Peters, Carpinello, Mugglin and Kane, JJ., concur. Adjudged that the petition is dismissed, as moot, without costs.
