Petitioner was found guilty of violating the prison disciplinary rules that prohibit disobeying an order, possession of a controlled substance (marihuana) and assault upon a staff member. There is no merit to petitioner's contention that he was denied effective employee assistance at his disciplinary hearing. The assistant's inability to present the testimony of two inmate witnesses and certain requested documents was not the result of ineffectiveness but was instead due to circumstances beyond his control, e.g., the witnesses could not be located despite reasonable efforts to do so and the documents were privileged or, in some cases, nonexistent ( see, Matter of Green v. Coombe, 234 A.D.2d 756, 757; Matter of Gonzalez v Mann, 186 A.D.2d 876, 877). Petitioner's remaining contentions have been examined and found to be similarly without merit.
Mikoll, J. P., Mercure, White, Yesawich Jr. and Peters, JJ., concur. Ordered that the judgment is affirmed, without costs.
