Following a tier III disciplinary hearing, petitioner was found guilty of violating the prison disciplinary rules that prohibit fighting and assaulting another inmate. The charges stem from an altercation between petitioner and his cellmate assistant wherein petitioner used the footrest of his wheelchair to hit his cellmate on the wrist. On administrative appeal the determination was modified to the extent of dismissing the charge of fighting. Petitioner commenced this CPLR article 78 proceeding challenging the determination.
Initially, we note that petitioner's plea of guilty with an explanation to the charge of assaulting another inmate precludes any challenge to the determination as not supported by substantial evidence ( see Matter of Cendales v. Goord, 305 AD2d 824; Matter of Anderson v. Goord, 262 AD2d 896). In any event, the misbehavior report, testimony at the hearing and petitioner's own admissions provide substantial evidence to support the determination ( see Matter of Jones v. Goord, 274 AD2d 902, 903; Matter of Anderson v. Goord, supra). Furthermore, the record belies petitioner's contention that the Hearing Officer was biased or ignored petitioner's justification defense. Petitioner's remaining contentions, having not been raised at the administrative hearing, are not preserved for our review ( see Matter of Lopez v. Goord, 14 AD3d 771).
Adjudged that the determination is confirmed, without costs, and petition dismissed.
