BTW, the case had nothing to do with abortion, as Thomas pointed out; it had to do with determining whether there was an implied private right of action that would give rise to a cause of action on the part of a private person if a state removes, or potentially if it fails to list, a particular Medicaid provider in the state’s Medicaid providers list.
There is a circuit split, with several going one way, and one circuit going the other.
The circuit split should be resolved, of course, but perhaps the justices felt that there would be too much time wasted by all sides on briefing the peripheral issues of abortion, and not enough on briefing the central issues, which do not have much to do with abortion.
