WASHINGTON — The Supreme Court on Friday night put off a decision about whether a restrictive Louisiana law that could close some of the state’s abortion clinics can go into efffect Monday.

The court said the law, which challengers said would leave the state with only one doctor eligible to perform abortions, cannot be implemented before Thursday. Challengers have asked it not be allowed to go into effect before the Supreme Court reviews it.

“Because the filings regarding the application for a stay in this matter were not completed until earlier today and the justices need time to review these filings,” the decision by the U.S. Court of Appeals for the 5th Circuit is temporarily stayed, wrote Justice Samuel Alito Jr. He is the justice responsible for receiving emergency requests from that appeals court.

The Louisiana law – passed in 2014 but never allowed to go into effect – requires any physician providing abortion services to have admitting privileges at a hospital within 30 miles of the procedure.

Even Louisiana acknowledges that the requirement is virtually identical to a Texas law that the Supreme Court voted 5 to 3 to strike down in 2016. The court said the admitting privilege requirement “provides few, if any, health benefits for women, poses a substantial obstacle to women seeking abortions, and constitutes an ‘undue burden’ on their constitutional right to do so.”

Hospitalization after an abortion is rare, all sides agree, and the lack of admitting privileges by the doctor who performed the procedure is not a bar to the woman getting needed medical care.

But last fall, a panel of the U.S. Court of Appeals for the 5th Circuit in New Orleans upheld the Louisiana law in a 2-to-1 vote, finding factual distinctions between how the restriction played out in Texas and Louisiana. The full court, considered one of the most conservative of the regional appeals courts, voted not to reconsider the panel’s decision.

The 2016 decision, Whole Woman’s Health v. Hellerstadt, was decided by a very different eight-member Supreme Court in the wake of conservative Justice Antonin Scalia’s death.

Justice Anthony Kennedy joined the court’s liberals to strike down the Texas law.
