The district court ruling in NJ was to block various aspects of NJs law, if the 3rd circuit panel refuses to stay the TRO, if NJ appeals to SCOTUS, they’ll refuse to intervene there too. These decisions by the district courts are on TROs and preliminary injunctions, they are not rulings in the merits. SCOTUS almost never gets involved in situations like this, they allow the lower courts to resolve things.
In NY two district court judges issued TROs and the 2nd circuit stayed those and set a date FTO hear NYs appeal of those TROs which is the 3rd week of March. SCOTUS is allowing the 2nd to hear that appeal, after the 2nd issues a ruling the loser could appeal to SCOTUS.
A denial by SCOTUS to hear anything should not be taken as SCOTUS doesn’t want to intervene nor that SCOTUS agrees with the lower court. Denying an appeal at a very early stage is extremely common. People need to relax, these case won’t be settled in a month, it’s going to take 18-24 months to have finality or near finality.
