A federal judge has blocked an effort by the state of Mississippi to close its last remaining abortion clinic. The Jackson Women’s Health Organization faced closure under a new state law that would have forced all physicians who perform abortions to be OB-GYNs with the power to admit patients to local hospitals. The Jackson clinic does employ OB-GYNs, but only one has been able to obtain the necessary hospital privileges. Critics say the law would have forced women to drive hundreds of miles out of state in order to obtain an abortion. On Sunday — the day before it was to take effect — Judge Daniel Jordan of Federal District Court temporarily blocked the law and set a hearing for later this month.
