HARRISBURG, Pa. (AP) — A state employees union and seven Democratic lawmakers filed a lawsuit in Commonwealth Court on Monday seeking to stop the state from privatizing the management of the lottery, saying Republican Gov. Tom Corbett doesn’t have the authority to make such a move.

AFSCME Council 13 wants the court to prevent Corbett’s administration from implementing an agreement with Camelot Global Services to manage the $3.5 billion lottery, one of the nation’s largest. The lawsuit claims the Lottery Act of 1971 doesn’t give the governor the right to privatize the lottery without approval from the Legislature.
