I think this is one of those cases where the Feds have “no standing”.
Feds need to prove that the town has people who were unable to vote. Supposedly no one complained.
There’s a guy in our town who files frivolous ADA lawsuits. I personally know two businesses that either had to shut down and eventually reopen elsewhere or make utterly silly, but compliant and expensive, changes to the building. One store turned their public restroom that had been available for 35 years into a storage closet. There is now an “employees only” restroom. I’d wager a lot more people desperately need that old restroom than handicapped people who needed an ADA compliant restroom.
