COLUMBIA — Attorneys for South Carolina Gov. Nikki Haley and Occupy Columbia protesters are back in federal court over the use of Statehouse grounds.

At a hearing scheduled for Thursday, state attorneys will ask U.S. District Judge Cameron McGowan Currie to lift her injunction preventing the state from removing the protesters. The request comes after the Budget and Control Board unanimously approved emergency regulations banning camping and sleeping on Statehouse grounds.

The state’s ability to enforce the rule is contingent on Currie’s decision.

Last week, Currie ruled the protesters and their tents could stay while their lawsuit progressed, or until valid restrictions were put in place that applied to everyone, not just Occupy Columbia.

State law says emergency regulations are applicable in cases of “imminent peril to public health, safety, or welfare.”
