OPINION BY PRESIDENT JUDGE CRUMLISH, JR., November 2, 1987:
The Department of Corrections (Department) appeals a State Civil Service Commission (Commission) order reversing the Department's five-day suspension of Mark Ehnot from his position as Institutional Music Teacher I. We affirm.
The Department suspended Ehnot, a music teacher at the State Correctional Institution at Graterford, on the charge of "negligently" importing contraband methamphetamine into the Institution. The methamphetamine was found taped to the inside of Ehnot's music folder. It was stipulated that the contraband was planted there without Ehnot's knowledge by an inmate with a *610 personal vengeance against Ehnot. Institution officials discovered the contraband when, acting upon a anonymous tip, they searched Ehnot when he reentered the prison on the following day.
Section 803 of the Civil Service Act[1] requires that disciplinary suspensions be for good cause. The alleged "good cause" must relate to one's competence and ability to properly execute job duties.[2]Toland v. State Correctional Institution at Graterford, 95 Pa. Commonwealth Ct. 634, 506 A.2d 504 (1986).
The Commission concluded that the Department did not have "good cause" for the suspension because Ehnot had no duty to secure his personal effects since he had no knowledge that he was carrying contraband.
The Department contends[3] that it established good cause in that Ehnot neglected his duty to search his *611 personal effects before reentering the prison. We disagree.
The Commission properly concluded that the Department failed to establish that Ehnot had a duty to conduct a self-inspection and, therefore, the suspension was not for good cause. The Department produced no evidence of any rule or regulation imposing such a duty. Indeed, a Corrections Officer Captain testified that he knew of no such rule[4] and stated that Ehnot's duty as a music teacher is only to report security infractions to an officer if he is aware of such violations.[5]
Because Ehnot's actions do not relate to his competence and ability to perform job duties, they cannot supply the requisite "good cause" for a suspension.
The Commission's order is affirmed.
