From the Associated Press:
Environmental groups have filed to dismiss a federal free speech lawsuit against an upstate New York town.
The town board in Sanford, in Broome County, passed a resolution in September saying no further discussion of gas drilling and fracking would be allowed because the emotional debate was disruptive and repetitive.
The Natural Resources Defense Council and Catskill Citizens for Safe Energy filed a lawsuit in U.S. District Court in February on behalf of town residents who opposed the so-called "gag order."
On April 9, the board passed another resolution saying it rescinded the order but reserved the right to limit comments of any speaker to three minutes.
NRDC said Wednesday it was withdrawing the lawsuit.
