The state law requires abortion providers to have admitting privileges at nearby hospitals, a demand that some argued would have shuttered multiple abortion clinics.
Finally, Smith rejected the district court's factual finding that the law would make access to abortion more hard for 70 percent of women seeking abortions in the state.
The 5-4 vote means the state can not put into effect the law it passed, pending a full review of the case.
Kavanaugh wrote a dissent that said he would have let the law go into effect because the appeals court had said "the new law would not affect the availability of abortions from. the four doctors who now perform abortions at Louisiana's three abortion clinics".
The final vote was the order to keep Louisiana's admitting privileges law on hold while the court decides whether to add the case to its calendar for the term that begins in October.
The full Fifth Circuit then denied abortion providers' petition to rehear the case en banc with all of the court's current judges involved.
Justices Samuel Alito, Neil Gorsuch and Clarence Thomas sided with Kavanaugh but did not sign on to his written dissent. The Louisiana law was nearly identical to a Texas law the court struck down before Justice Anthony M. Kennedy retired.

Ray was allowed to meet with an imam earlier, and the religious leader watched from an adjoining room as Ray was put to death an hour after the Supreme Court rejected the stay request.
Thursday night's Louisiana ruling may have only delayed the coming upheaval.
If the court does not accept the case, the injunction ends and the state law would go into effect. "Essentially, he argues that there isn't yet any evidence that the Louisiana law will have any immediate effect on abortion access". Should the Court agree to hear the case, arguments would likely happen in the fall.
He added that if they cannot, "then even [Louisiana] acknowledges that the law as applied might be deemed to impose an undue burden".
One reason to grant a stay is because there is a substantial likelihood that the Court will ultimately take the case and then reverse the lower court.
