Was this a voted on decision by the full court? Or was it a situation where the individual justice who makes temporary decisions(on cases slated for the court) on a particular day, dropped this bomb?
The motion for a stay was voted on by the full Court. The Court's Order just says "stay denied,," without explanation (the usual course on a stay motion). Thomas and Scalia dissented, in a written opinion (unusual on a stay motion, but not unprecedented).
