A Montana judge rules that the state cannot limit voter registration to earlier deadlines and must allow registration on Election Day. The ruling blocks Montana’s attempt to restrict same-day registration, with the judge concluding that the change would disproportionately affect Native American and younger voters. The decision means eligible residents who have not previously registered can register and vote during the Election Day registration period, rather than being turned away due to earlier cutoff dates. The judge’s finding centers on the unequal impact of restricting registration access, rather than on whether election administration goals could be achieved through other measures. The ruling applies to the contested policy and prevents the state from implementing the restriction as described in the case. The decision comes amid ongoing legal scrutiny of election rules that govern registration deadlines and voting eligibility. Further steps, including any appeals or additional court proceedings, are not detailed in the provided information.
