CONCORD, N.H. – A recent ruling by a federal judge has significant implications for voter registration processes in New Hampshire. The decision mandates that the state simplify its voter registration by allowing applicants to attest to their U.S. citizenship when they lack the necessary documentation. This ruling comes during a broader national discussion on voter identification laws, which have been championed by various political figures, including former President Donald Trump.
U.S. District Court Judge Samantha Elliot’s ruling is a pivotal moment in this ongoing debate. While she refrained from addressing the constitutionality of requiring proof of citizenship outright, her focus on New Hampshire law brought to light the potential dangers of imposing strict requirements for voters. Her ruling, issued late Thursday, found that recent amendments to the state’s voter registration law unconstitutionally eliminated the option for voters to use a sworn affidavit as a method of proving their citizenship.
“The evidence shows that this is the only method of proof available to a significant number of New Hampshire voters,” Judge Elliot stated in her decision. This insight underscores the importance of accessibility in the voting process, particularly in a state known for its low barriers to entry for voter registration.
The changes in question were implemented following the signing of a law by former Governor Chris Sununu, a Republican, two years ago. Following the ruling, the attorney general’s office announced plans to appeal, maintaining that the requirements were a “common-sense approach to voter registration and election administration designed to protect the integrity of our elections.”
This ruling is a significant victory for the American Civil Liberties Union (ACLU) of New Hampshire and other plaintiffs who argued that the recent changes imposed unnecessary burdens on eligible voters. “New Hampshire’s elections have always been safe, secure, and accurate — and this law could have unconstitutionally and needlessly prevented thousands of eligible voters from casting a ballot,” stated Henry Klementowicz, deputy legal director of the ACLU of New Hampshire.
The lawsuit was brought forth by a coalition of organizations including the Coalition for Open Democracy and the League of Women Voters of New Hampshire. They described New Hampshire’s voter registration law as among the most restrictive in the country. In the previous town elections, many voters faced difficulties in obtaining passports, birth certificates, or other necessary documentation to prove their citizenship.
New Hampshire is not alone in its efforts to enforce proof-of-citizenship laws; states like Arizona, South Dakota, Utah, and Wyoming have similar regulations in place. Florida recently enacted a law requiring documentary proof of citizenship to vote, set to take effect next year. Historical context reveals that a similar law in Kansas was found unconstitutional in 2018 after it prevented over 31,000 eligible citizens from registering to vote.
In Arizona, a two-tiered system was established following a 2013 U.S. Supreme Court ruling that prohibited requiring citizenship documentation for federal elections. The legal battle continues, as parts of Arizona’s proof-of-citizenship law were allowed to be enforced as the court proceedings unfold.
This ruling emerges amidst ongoing efforts by Trump to push a proof-of-citizenship bill, known as the SAVE America Act, through Congress. Advocates for voting rights argue that such a federal mandate could disenfranchise millions. A study conducted by the University of Maryland in 2025 estimated that around 21.3 million eligible American voters lack the necessary documents to prove their citizenship, highlighting the potential risks posed by strict voter ID laws.
