Kane, J.
Petitioner was charged with violating prison disciplinary rules prohibiting possession of unauthorized property, possession of authorized property in an unauthorized area, smuggling and unauthorized exchange after an envelope containing $45.14 in stamps and reflecting the return address of another inmate was recovered from petitioner during a random pat frisk. Following a tier III disciplinary hearing, petitioner was found guilty of all charges. After the determination was affirmed on administrative appeal, petitioner commenced this proceeding.
We confirm. The misbehavior report and testimony of the authoring correction officer provide substantial evidence to support the determination of guilt ( see Matter of Karlin v. Goord, 13 AD3d 697, 698; Matter of Knight v. McGinnis, 10 AD3d 754, 755; Matter of Selby v. Coombe, 249 AD2d 635, 636). Petitioner had no standing to challenge the manner in which the envelope was opened because it was not his mail; it contained the return address of another person and he initially informed the correction officer that it did not belong to him ( see People v. Miller, 228 AD2d 979, 980, lv denied 88 NY2d 990).
With respect to petitioner's procedural claim, although the employee assistant failed to interview the correction officer as requested by petitioner, the Hearing Officer called the officer as a witness and petitioner declined the opportunity to examine him. Accordingly, petitioner failed to demonstrate any prejudice flowing from the assistant's alleged inadequacy ( see Matter of Tusa v. Goord, 287 AD2d 907, 908, appeal dismissed 98 NY2d 646). Petitioner's remaining arguments have been reviewed and found lacking in merit.
Adjudged that the determination is confirmed, without costs, and petition dismissed.
