Why it matters: It would be highly unusual for the court to so quickly turn its back on one of its precedents, but that's what the justices would need to do to uphold Louisiana's restrictions, Axios' Sam Baker notes.

• Brett Kavanaugh, who replaced Kennedy, "has indicated his willingness to undermine or discard the 2016 decision," NPR's Nina Totenberg reports.

Between the lines: This is a deliberate strategy, by red states as well as the conservative legal establishment, to force big abortion cases before the court and provide it the opportunity to roll back abortion rights, per Sam.
