MATTER OF ESTRELLA v. COUGHLIN

Ordered that the judgment is affirmed, without costs or disbursements.

As the appellants failed to introduce any evidence that the confidential information they had received was from a reliable source, which is required before a prisoner can be ordered to undergo urinalysis (see, New York Dept of Correctional Servs Directive 4937 [D] [1] [d], now 7 NYCRR 1020.4 [a] [4]), the Supreme Court properly concluded that the determination dated July 22, 1985, should be vacated, the charges dismissed, and all mention of those charges expunged from the petitioner's institutional record. Mangano, J.P., Niehoff, Spatt and Harwood, JJ., concur.
