Supreme Courts lay out procedural rules for lower courts all the time, they routinely review those courts conduct to see if those rules are being followed, and they’re fully able to find people in contempt of court if those rules aren’t being followed. The state’s legislature or the federal DOJ could certainly get involved here to try to hold these lower courts accountable as well, but the notion that the Supreme Court is powerless here is just a bullshit dodge from someone who doesn’t want to do their job properly because he knows it will upset powerful people.
