Maddy summaryHB 133 modifies the process for new residents moving to the state who need to transfer their out-of-state driver's licenses. It specifies clear timelines for the Division of Motor Vehicles (DMV) to send violation notices to drivers and allocates funds to the DMV for technology upgrades needed to meet state legal requirements. The bill directly affects new residents required to obtain a state license and the DMV, which must implement these changes. Key provisions include updated license transfer rules, standardized violation notice procedures, and dedicated funding for necessary technological improvements to ensure compliance.

relative to the term for supervisors of the checklist.

Maddy summaryHB 151, titled "relative to the term for supervisors of the checklist," appears to be a procedural bill adjusting term lengths for a specific administrative position. The bill was enacted after passing through legislative chambers and receiving the Governor's signature on July 7, 2025, with an effective date of September 13, 2025. The provided context does not specify the exact role of "supervisors of the checklist" or the nature of the term changes, so no concrete policy details can be summarized. As a procedural measure, this bill focuses on administrative structure rather than substantive policy.

Co-sponsor HB 560
Signed into law · New Hampshire House · Co-sponsor
relative to parental access to a minor child's medical records, relative to refusal of consent to testing to determine alcohol concentration and penalties for aggravated driving while intoxicated, defining pre-sequestration timber tax revenue, establishing a moratorium on carbon sequestration and establishing a commission to study the effects of carbon sequestration in New Hampshire forests upon state and local tax revenue, effective forest management, and the health of New Hampshire’s logging industry.

Maddy summaryHB 560 is a multi-topic bill that bundles four distinct policy proposals. It would allow parents access to their minor children's medical records, impose penalties for refusing alcohol concentration testing, define how pre-sequestration timber tax revenue is handled, and establish a moratorium on carbon sequestration projects in New Hampshire forests while creating a commission to study their impact on tax revenue and the logging industry. The bill does not create a single unified policy but combines these separate provisions. Key mechanisms include new parental access rules for medical records, penalties for refusing alcohol tests, and a temporary pause on carbon sequestration projects with a mandated study. This bill directly affects parents, healthcare providers, drivers facing alcohol testing, and entities involved in forestry and carbon sequestration in New Hampshire.

relative to the penalty for trafficking in persons under 18 years of age.

Maddy summarySB 262 increases penalties for trafficking individuals under 18 years old by reclassifying the offense as a felony instead of a misdemeanor. This bill directly affects individuals convicted of trafficking minors, imposing stricter criminal consequences. The key provision raises the maximum penalty for this crime, enhancing legal accountability for traffickers. The bill was signed into law on June 24, 2025, and takes effect January 1, 2026.

Co-sponsor SB 212
Signed into law · New Hampshire Senate · Co-sponsor
changing references from "votes" to "ballots" in the laws regarding elections.

Maddy summarySB 212 updates election law terminology by replacing "votes" with "ballots" in specific sections of New Hampshire's election statutes (RSA 659:88 and 659:91-a). It does not change any substantive requirements for write-in nominations or vote thresholds - candidates still need 35 write-in ballots or 10% of total ballots cast to qualify. The bill directly affects election administrators and candidates navigating primary election rules, ensuring consistent language in legal references. This is a purely terminological adjustment with no policy impact, as the 35-ballot or 10% requirements remain unchanged. The bill became law on June 17, 2025, after passing both chambers and receiving gubernatorial approval.

Co-sponsor HB 210
Failed · New Hampshire House · Co-sponsor
establishing a commission to study the state flag and its history.

Maddy summaryHB 210 establishes a 7-member commission to study New Hampshire's state flag. The commission includes three House members (with party balance), one Senate member, and representatives from the New Hampshire Historical Society and the New England Vexillological Association. It will review the flag's history, examine U.S. state flag design standards, and develop criteria for public submissions and a public hearing to narrow design options. The bill does not propose changing the flag but creates a structured process for potential future consideration. This is a procedural bill focused on gathering information, not implementing policy changes.

Passed · New Hampshire House · Co-sponsor
urging the United States government to investigate allegations of abuse of minorities, especially Hindus, Buddhists, Christians, and other religious minorities by the interim government of Bangladesh.

Maddy summaryThis resolution (HR 11) urges the U.S. government to investigate alleged abuses against religious minorities in Bangladesh, specifically targeting Hindus, Buddhists, Christians, and other minority groups. It cites claims of increased attacks on places of worship (including 50 shrines burned) and harassment under Bangladesh's interim government, though it does not mandate any action. The bill is a symbolic resolution (not a law) directed at the U.S. Secretary of State, President, and White House, requesting they examine these allegations. It does not create new policies or affect any U.S. citizens directly.

relative to restrictions on elective abortion.

Maddy summaryHB 476 restricts abortions after 15 weeks gestation in New Hampshire, making "late-term elective abortion" illegal unless a medical emergency (defined as conditions endangering the mother's life or causing serious bodily harm) or a fetal abnormality incompatible with life exists. Healthcare providers must perform an ultrasound to determine gestational age before 15 weeks and report medical emergency justifications to health authorities. Violations carry criminal penalties (class B felony with fines up to $100,000) and civil liability for damages. The law affects healthcare providers performing abortions and pregnant individuals seeking later-term procedures, with exceptions for medical emergencies or fatal fetal conditions. It takes effect January 1, 2026.

permitting classification of individuals based on biological sex under certain limited circumstances.

Maddy summaryThis bill allows organizations and individuals to classify people based on biological sex in specific situations without it being considered unlawful discrimination. It explicitly permits this classification in three areas: shared restrooms and locker rooms, athletic competitions where physical strength or speed is a factor, and certain correctional or involuntary commitment facilities. By adding these exceptions to the state's Law Against Discrimination, the legislation clarifies that separating individuals by biological sex in these contexts does not violate protections against discrimination based on gender identity or sexual orientation.
