Apparently, the last ruling was from the New Mexico state Supreme Court. I don’t know the process and how they went immediately to the US Supreme Court.
Perhaps Scotus reason was that it hadn’t gone through the process of appeal. The article didn’t list any reason from the Scotus other than that they declined the case.
That is the “excuse” the court gave. But they had the ability to accept it, especially since it is harming people right now. Same with the NSA domestic spying case.
They avoid doing their job where it counts most.
