    In the Matter of Robert Salmon, Petitioner, v Thomas A. Coughlin, III, as Commissioner of the Department of Correctional Services, et al., Respondents.
    Proceeding pursuant to CPLR article 78 (transferred to this court by order of the Supreme Court, entered in Ulster County) to review a determination of respondent Commissioner of Correctional Services which found petitioner guilty of violating a prison disciplinary rule.
   Casey, J.

Petitioner, a prisoner at Eastern Correctional Facility in Ulster County, was charged in a misbehavior report with violating an institutional rule which prohibits inmates from possession of controlled substances. The report was based on a random frisk conducted at the yard gate by Correction Officer W. Young, who authored the report. The frisk of petitioner revealed "what was believed to be (7) seven rolled marijuana cigarettes” in petitioner’s right sock. Correction Officer L. Distel performed two NIK tests, both of which identified the substance in the cigarettes as marihuana. Based on the misbehavior report, the statement of Correction Sergeant B. Binkley corroborating that report and Distel’s test report, petitioner was found guilty and sentenced to 120 days in special housing unit with loss of privileges. On administrative appeal, the determination was modified to 90 days in special housing unit and loss of privileges.

The sequential positive results of the two tests, when coupled with Young’s personal observation and the reports of the officers also identifying the substance as marihuana, provided substantial evidence on which to base the determination (see, Matter of Darnell v Kuhlmann, 145 AD2d 852). Accordingly, the determination appealed from should be confirmed.

Determination confirmed, and petition dismissed, without costs. Mahoney, P. J., Casey, Weiss, Levine and Harvey, JJ., concur.
