SCOTUS only denied emergency injunction, not the merits. The opposition’s brief said that it would violate separation of powers for SCOTUS to intervene and I think they bought that argument. However, nothing prevents them from declaring that the election violated the constitution and should be placed in hands of the PA legislature.
