Nobody voted in favor of Biden’s restrictions. Biden’s restrictions were not before the Court.
The vote was in favor of letting the case go through the normal appeals process. When the case gets to the Supreme Court, Biden’s restrictions could very well be slapped down (or Biden’s restrictions could be rejected by an Appeals Court before the case ever gets to the Supreme Court).
That needs to be reiterated. This is just SCOTUS letting things proceed through regular channels first. They haven’t really “ruled” on anything yet.
The case is on the docket for the appeals court, and regardless of this ruling it will hear arguments next month -- well, it's supposed to be next month. I won't be surprised if the federal government now tries to delay so that they can get their way for as long as they can postpone progress of the case to its eventual hearing before the Supreme Court.
The request [for a stay] was supported by March for Our Lives, Everytown for Gun Safety Action Fund and the Brady Center to Prevent Gun Violence. The attorney general for Washington, D.C., joined by 20 Democratic state attorneys general, also filed an amicus brief backing the Biden administration.
Even if I knew nothing else of the case, seeing this list of people FOR lifting the stay ensures that I want to be AGAINST it.
