My problem with that is “why slap them and tell them to reconsider?” Why not just vacate the 7th’s ruling altogether on the side of Notre Dame?
The reconsideration is actually the neatest part of this ruling. What SCOTUS is saying, in a decidedly school marmish tone is: “You were wrong. Now show us you know you were wrong. In your own words.”
Then the Supreme Court would be slapping flies everywhere. No, the court effectively said 'Any court who tries this we will be reminded of our ruling in this way'.
