Boston, August 12, 2026

A federal court in Boston on Tuesday expanded its preliminary injunction against the tightening of mail-in voting rules planned by the US government under Donald Trump to all 50 states, and the injunction now applies nationwide.

The court in Boston expanded what had until now been a preliminary ban on the planned rules from 23 states to all 50 states, as set out in the preliminary injunction. The controversial new regulation is therefore now halted across the entire country for the time being.

Background of the Case

The background to the case is the US government's attempt to more tightly restrict access to mail-in voting through the US Postal Service (USPS). Critics, including prominent Democrats, had criticized the plans as a restriction of voting rights. The Department of Justice had previously pushed the regulation forward against resistance from Congress, in which both the Senate and the House of Representatives had in part raised sharp objections to the initiative.
