I might not understand the terminology or process here, but doesn’t SCOTUS often refuse to hear cases that aren’t worth their time? Last year they chose not to hear a number of second amendment cases where it seemed like there was much more on the line and they would have overturned lower court rulings, so I’m surprised they chose to spend time on this one, which seems uncontroversial given the 9-0 vote.
