There is indeed something to get around in the Sierra case. The court issued a stay of an injunction. That is, in fact, the only thing that I could have meant about “getting around”. This current case includes the court inviting the petitioner to request a similar injunction.
You can’t stop the wall in one jurisdiction, you try to get a similar injunction in another jurisdiction.
Of course the SC hasn’t stayed the second temporary injunction. The El Paso court has just invited the petitioner to request such an injunction.
We will see if, once this injunction is granted, if the SC doesn’t consider this as a way to get around Trump v Sierra.
