Anti-voter law was among the most restrictive in the United States, and placed unconstitutional burdens on voters

CONCORD, N.H. - Last night, the federal court in New Hampshire struck down the state’s anti-voter law enacted in 2024, declaring it unconstitutional. The law, known as HB 1569, created some of the strictest registration requirements in the nation and, among other things, required documentary proof of citizenship for voter registration.

According to the Court’s decision, the law "constitutes an unjustifiable burden on the right to vote in violation of the First and Fourteenth Amendments,” “does little, if anything, to further the state’s interests,” and also “violates voters’ rights to procedural due process.”
[…] HB 1569 required documentary proof of citizenship for voter registration — documents like a passport or birth certificate, which many people do not have or cannot easily access — making it materially harder, if not impossible, for thousands of New Hampshire citizens to exercise their right to vote.

The Court’s decision is in line with other federal courts that have weighed in on this issue previously. For instance, federal courts struck down a similar Kansas law, which imposed a proof of citizenship requirement for state and federal elections, as violating both the U.S. Constitution and National Voter Registration Act of 1993.
