Rob Annicelli, head of an anti-slots coalition in the area, said Monday that the petition was approved last week by the elections board and county legal department. If enough county residents sign the petition, voters will be able to decide whether to reject the casino site.
Baltimore developer David Cordish's 4,750-slot-machine facility, on a parking lot near the food court of Arundel Mills mall, was approved Dec. 21 by the county council.
Slots opponents have little more than a month to collect at least half the needed signatures, Annicelli said. If they succeed, they get another 30 days to gather the rest, he said.
