Why it matters: The court’s 5-4 ruling largely leaves the status quo of abortion law unchanged, affirms the court’s precedents and leaves big decisions about the future of abortion access for another day.

Chief Justice John Roberts joined the court’s more liberal justices in the decision.

The big picture: Louisiana had required abortion providers to maintain admitting privileges at a nearby hospital. The Supreme Court struck down nearly identical requirements, out of Texas, in 2016. And the justices said today that their earlier decision controls this case, too.
