The lawyer representing a group of current and former Georgia lawmakers who failed to stop a Fulton County tax increase from going into effect in court says he hopes the judge will rule quickly on the underlying issue: whether the hike is legal at all.

Following a hearing on Thursday, Cobb County Superior Court Senior Judge G. Grant Brantley denied from the bench the lawmakers’ request for a temporary injunction barring the 17 percent tax hike from proceeding. His staff attorney, Thomas Davis, said a written order likely would be filed soon.
