Petitioner commenced this CPLR article 78 proceeding challenging a determination finding him guilty of violating the prison disciplinary rules that prohibit harassment, impersonation and facility correspondence violations. 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 Messer v. Selsky, 295 AD2d 664).
Adjudged that the petition is dismissed, as moot, without costs.
