The 5-4 decision, in which Chief Justice John Roberts joined with the court's four more liberal justices, struck down a law passed by the Louisiana Legislature  in 2014 that required any doctor offering abortion services to have  admitting privileges at a hospital within 30 miles. Its enforcement had  been blocked by a protracted legal battle.
Two Louisiana doctors and a medical clinic sued  to get the law overturned. They said it would leave only one doctor at a  single clinic to provide services for nearly 10,000 women who seek  abortions in the state each year.
The  challengers said the requirement was identical to a Texas law the  Supreme Court struck down in 2016. With the vote of then-Justice Anthony  Kennedy, the court ruled that Texas imposed an obstacle on women  seeking access to abortion services without providing any medical  benefits. Kennedy was succeeded by the more conservative Brett  Kavanaugh, appointed by President Donald Trump, who was among the four  dissenters Monday.
Justice Stephen Breyer, who wrote the Texas  decision, also wrote Monday's ruling. The law poses a substantial  obstacle to women seeking abortions and offers no significant health  benefits "and therefore imposes an undue burden on a woman's  constitutional right to choose to have an abortion."
Roberts  said he thought the court was wrong to strike down the Texas law, but  he voted with the majority because that was the binding precedent.

The Center for Reproductive Rights said the  burdens on access to abortions in Louisiana would have been even more  restrictive than those in Texas, where about half of the state's  abortion clinics were forced to close. It also said the law was  unnecessary, because only a small fraction of women experience medical  problems after abortions, and when they do, they seek treatment at  hospitals near where they live, not ones near the medical clinic.
"As  Republicans continue their assault nationally on Roe v. Wade, they are  also fighting on a state by state basis," House Speaker Nancy Pelosi,  D-Calif., said in a statement. "Louisiana's draconian abortion ban was a  clear and intentional violation of the Constitution, explicitly  designed to permanently destroy women's reproductive freedoms and  dismantle their right to make their own decisions about their health,  bodies and timing and size of their families."
Louisiana  had defended the law, arguing that the requirement to have an  association with a nearby hospital would provide a check on a doctor's  credentials. But opponents said a hospital's decision about whether to  grant admitting privileges had little to do with a doctor's competence  and more to do with whether the doctor would admit a sufficient number  of patients.
