Judge David O. Carter on 28 October and a 9th Circuit panel, 2-1 on 30 October, refused the Justice Department's demand that California set aside about 20,000 mail ballots.
Judge David O. Carter refused on 28 October to make California set aside about 20,000 mail ballots that the Justice Department called likely non-citizen votes. A federal appeals panel refused the department again, 2-1, on 30 October.

Local voters rejected 40 of 41 data-centre measures on 3 November; only Harwood, North Dakota approved one, CNBC reported.
United StatesVoters sided against data centres in 40 of 41 local ballot measures on 3 November, CNBC (the US business news channel) reported. The exception was Harwood, a town in North Dakota, where voters rejected extra review of industrial projects.
Each measure was a local question, settled town by town. They went to voters on the same day as the national vote for Congress, and almost every result went against the data centres.
Sideways, with two live pressure points. In Mississippi, Colom's campaign says about 15,000 affidavit ballots remain, and a recount needs a court order, so litigation after the 10 November cure deadline is the likeliest route to a contested result. In Alaska, DOJ says it will appeal Judge Sharon Gleason's dismissal of 1 November 2026, but every court that ruled before polling day, the 9th Circuit on 30 October included, refused to set ballots aside.
