The civic evidence room
Not “who is right”. The question is which institution holds which authority, and at what stage.
The holding
Congress has not delegated authority over mail-in voting to the Postal Service.
What it does not bar: The ruling does not bar non-binding postal guidance on ballot envelopes.
Still open
- Supreme Court action on the pending application.
- Appellate outcome in the First Circuit.
- Whether any part of the order is operative in November.
Test a claim against the holding
Every verdict below quotes what the ruling actually says. None of them is an opinion about the policy.
The executive
Can: Issue an order directing an agency to act.
Cannot: Grant itself an authority Congress has not delegated.
An agency
Can: Implement what it is directed to do, within its statutory authority. Issue non-binding guidance.
Cannot: Act where the enabling statute does not reach.
A district court
Can: Enjoin a provision — pause it — as to named parties.
Cannot: Cancel an order. An injunction pauses; it does not repeal.
A court of appeals
Can: Leave an injunction in place, stay it, or reverse it.
Cannot: Reach an issue nobody appealed.
The Supreme Court
Can: Grant or deny relief on an emergency application; take the case later.
Cannot: Act before somebody asks.
Congress
Can: Delegate the authority, and settle the question outright.
Cannot: Be assumed to have delegated it. That assumption is the whole dispute.
