WASHINGTON — The Supreme Court on Friday temporarily blocked a Louisiana law that its opponents say would leave the state with only one abortion clinic. The court gave no reasons, though it did say that its order was “consistent with” one last June that blocked part of a Texas abortion law.

The move came two days after the Supreme Court heard arguments in the Texas case, and abortion rights groups said they hoped that the development Friday was a sign that they had secured five votes to strike down the Texas law.

Only Justice Clarence Thomas noted a dissent from the order Friday, suggesting that the vote had been 7 to 1, but justices do not always disclose their dissenting votes on such orders. In the order blocking the Texas law in June, the court’s four most conservative members noted their dissents, making it clear that the vote had been 5 to 4.

The order Friday suggested that the Louisiana law would remain blocked until the court renders its decision in the Texas case, Whole Woman’s Health v. Hellerstedt, No. 15-274.
