The U.S. Supreme Court has agreed to hear a challenge to a sweeping anti-choice law in Texas, marking what could be the most significant abortion rights case in decades. The case was brought by abortion providers against a law which could shutter all but 10 clinics in Texas if it comes into full effect. Already, about half of the more than 40 clinics in Texas have been forced to close under the law. In a statement Friday, the Center for Reproductive Rights, which represents the plaintiffs, said, “Today the Supreme Court took an important step toward restoring the constitutional rights of millions of women, which Texas politicians have spent years dismantling.” Justice Anthony Kennedy is expected to be the key swing vote in the case, which could shape the future of abortion access nationwide.
