Annotation by Marcus Bell on Supreme Court denies Trump administration’s request to implement parts of rule on mail-in voting

“In an order issued on Monday night, the court indicated that the “Government is unlikely to succeed on the merits of its challenge to” Talwani’s order – a key factor in determining whether to grant the relief that the government was seeking. “And the equitable factors applicable for obtaining emergency relief from this Court” – such as whether the government will be permanently harmed if Talwani’s order is not put on hold – “do not favor a stay,” the court added.”

The easy take is that this was a timing loss for the mail-ballot rule, and the Court's own order doesn't read that way to me. It says the government is unlikely to succeed on the merits of its challenge, then adds that the equities don't favor a stay either. Only one of those sounds like a calendar. The lawful-but-late reading leans on Kavanaugh's concurrence, which is one justice's paragraph.

For Sacramento readers: California led the 23 states, but the injunction keeps the rule out of November's elections nationwide, and it holds while the case goes on in Judge Talwani's court in Boston. California mails a ballot to every active voter, so the rule's list of mail-ballot voters for a USPS portal would have been every active voter in the county.

Careful with 'unlikely to succeed on the merits of its challenge.' The challenge is to the injunction, which isn't the same as a finding on whether USPS has the power, and the injunction can stand on the calendar alone. I mostly meet the APA through federal transit rules, and Kavanaugh is using its standard here: rolling this out now would be 'arbitrary and capricious.' So I don't think the order splits into a timing half and a law half the way you want it to.

“Justice Brett Kavanaugh, a Trump appointee, concurred with the ruling in a statement that said, "there is at least a fair prospect that the final rule falls within the Postal Service's statutory authority." "But applying the rule in the 2026 elections would be arbitrary and capricious in violation of the Administrative Procedure Act because state and local election officials do not have sufficient time to reasonably implement the rule before the elections," Kavanaugh added.”

@marcusbell howe on PBS, from 0:22: nobody has to note a dissent on an unsigned order, so it 'could be 7 to 2' or there were quiet no votes. then her count: kavanaugh's 'fair prospect' plus alito and thomas is 3, 'you need 2 more,' and she thinks the door's open 'at least a crack.' so 'the Court's own order' might be five votes. i wouldn't call a series after game one.

@rachelkim fair, I read 'merits' as the authority question and it doesn't have to be. Nothing in the order calls the rule lawful either, though.

I'm with the calendar reading. Sternberg on WSJ's Potomac Watch (2:16) splits the rule. The envelope marking he reads as meant to get ballot mail handled more efficiently, so ballots don't get lost and turn up in the trunk of a van two weeks after the election. The voter lists going to USPS are the 'headscratcher,' federal interference he calls 'counterproductive.' He never says unlawful. What he has trouble seeing is how it gets done 'before this election' without hiccups.

@owenprice the envelope half has a catch. Per the whistleblower, USPS would sample each bulk mailing, and if one envelope failed the check, even by mistake, the whole mailing would go back to the state. That's lot sampling with zero tolerance. Lot quality surveys of vaccine coverage usually allow a few misses before a lot fails. And by the same account the system hadn't been properly tested.

“As planned, the Postal Service system would take a random sample of bulk mail ballots going to voters to make sure the envelopes all contained required information, including special bar codes tied to each voter. If the computers found that one ballot failed the check, even if it was a mistake, the Postal Service system would reject all the ballots in the mailing and send them back to the state.”

Alito didn't wave the calendar away, to his credit. He takes it 'very seriously' and suggests the challengers and the courts 'bear a substantial share of the blame' for the delay. What he weighs against it is fraud detection. That's a screening argument, and I can't judge a screening test without the prevalence. Does anyone have a number?

“"The Government has a strong interest in enforcing the rule, and implementing it will also 'enhance the visibility of Federal Ballot Mail' in order to better detect election fraud," Alito wrote.”

@gracewhitfield the closest number I trust is for noncitizen voting, the eligibility question the voter lists are about. Miles Parks on the NPR Politics Podcast, on what experts expect: 'much fewer than 1%, probably fewer than one-tenth of a percent.' I haven't charted it, because of the caveat in the same episode: NPR asked DHS and Census for their methodology and neither answered.

“But I do think that what you can say confidently is that every time a state or government entity has looked at the idea of noncitizen voting, the numbers are minuscule. They are not zero.”

@elliebrennan 'They are not zero' is the part I'd underline. Under a tenth of a percent washes out in most statewide races. Not in a county race decided by a few dozen votes. Still doesn't make a USPS portal the fix.

@owenprice Talwani doesn't split your two halves. Her line covers USPS and election mail as a whole. If the envelope half comes back, I'd expect it through Congress. Would you back it then?

““The court is unaware of, and no party has proffered, any delegation Congress has made that would permit the USPS to regulate election mail,” Talwani wrote.”

Tammy Patrick, who spent 11 years as an election official in Arizona, on the reaction from the state officials she'd talked to: 'a collective sigh of relief,' because doing this with ballots already out was 'almost an impossible ask.' The friend-of-the-court brief in the SCOTUSblog piece, from election officials including Republican secretaries of state in six states, said much the same. Two seniors at my school, both first-time voters, asked me this week whether they can still vote by mail. I sent them to the county elections page instead of trying to explain a stay.
