Today's three SCOTUSblog commentators aren't claiming "Victory" in yesterday's 5-4 ruling striking down Louisiana's patently unconstitutional abortion law: https://www.scotusblog.com/category/special-features/symposia-on-rulings-from-october-term-2019/symposium-on-the-courts-ruling-in-june-medical-services-v-russo/.
They're right to be worried. Justice Roberts made it perfectly clear that on the merits he believes Louisiana was within its rights to require doctors who perform abortions to have admitting privileges in a nearby hospital.
This, of course, is a position the Court rejected four years ago in Whole Women's Health, which involved a nearly identical Texas requirement (and from which CJ Roberts dissented). But doing the math in 2020, there are now five justices who believe Whole Women's Health was incorrectly decided. Chief Justice Roberts' concurring opinion yesterday was based on the slenderest of reeds -- stare decisis -- and, although it provided the fifth vote to doom the Louisiana law, clearly signaled that a majority of the Court is open to an interpretation of Casey's "undue burden" test that allows states to impose draconian and unjustifiable burdens on a woman's right to choose.
The Roe/Casey consensus hangs by the slenderest of threads.
