The Massachusetts State House is topped with a golden dome, and faces Boston Common on Beacon Hill.
Massachusetts has a long political history; earlier political structures included the Mayflower Compact of 1620, the separate Massachusetts Bay and Plymouth colonies, and the combined colonial Province of Massachusetts. The Massachusetts Constitution was ratified in 1780 while the Revolutionary War was in progress, four years after the Articles of Confederation was drafted, and eight years before the present United States Constitution was ratified on June 21, 1788. Drafted by John Adams, the Massachusetts Constitution is the oldest functioning written constitution in continuous effect in the world.[349][350][351] It has been amended 121 times, most recently in 2022.[352]
Massachusetts politics since the second half of the 20th century have generally been dominated by the Democratic Party, and the state has a reputation for being the most liberal state in the country.[353] In 1974, Elaine Noble became the first openly lesbian or gay candidate elected to a state legislature in US history.[354] The state's 12th congressional district elected the first openly gay member of the United States House of Representatives, Gerry Studds, in 1972[355] and in 2004, Massachusetts became the first state to allow same-sex marriage.[64] In 2006, Massachusetts became the first state to approve a law that provided for nearly universal healthcare.[356][357] Massachusetts has a pro- sanctuary city law.[358] As of 2024, Massachusetts has a Democratic Governor, two Democratic Senators, and all nine Congressional Representatives are Democrats. Massachusetts is a blue state; Ronald Reagan was the last Republican to win the state in 1984.
In a 2020 study, Massachusetts was ranked as the 11th easiest state for citizens to vote in.[359]
Government
Main article: Government of Massachusetts
See also: Commonwealth (U.S. state)
Maura Healey ( D) is the 73rd Governor of Massachusetts.
The Government of Massachusetts is divided into three branches: executive, legislative, and judicial. The governor of Massachusetts heads the executive branch, while legislative authority vests in a separate but coequal legislature. Meanwhile, judicial power is constitutionally guaranteed to the independent judicial branch.[360]
Executive branch
As chief executive, the governor is responsible for signing or vetoing legislation, filling judicial and agency appointments, granting pardons, preparing an annual budget, and commanding the Massachusetts National Guard.[361] Massachusetts governors, unlike those of most other states, are addressed as His/Her Excellency.[361] The governor is Maura Healey and the incumbent lieutenant governor is Kim Driscoll. The governor conducts the affairs of state alongside a separate Governor's Council made up of the lieutenant governor and eight separately elected councilors.[361] The council is charged by the state constitution with reviewing and confirming gubernatorial appointments and pardons, approving disbursements out of the state treasury, and certifying elections, among other duties.[361]
Aside from the governor and Governor's Council, the executive branch also includes four independently elected constitutional officers: a [secretary of the commonwealth](https://en.wikipedia.org/wiki/Mas

Key Massachusetts Laws (23)
Operating Under the Influence (OUI)
Massachusetts OUI law forbids driving with a BAC of 0.08% or higher, or while impaired. First offenders typically receive the 24D alternative (probation, alcohol class, 45-90 day suspension). Penalties escalate sharply for repeat offenses; third offense is a felony.
Regulation of Recreational Marijuana
Massachusetts allows adults 21+ to possess up to 1 ounce in public or 10 ounces at home, and grow up to 6 plants per person. Retail marijuana is subject to approximately 20% combined state and local taxes. The Cannabis Control Commission oversees licensing.
Firearms Licensing and Assault Weapons Ban
Massachusetts requires a license for all firearm ownership. A License to Carry (LTC) is needed for handguns, while a Firearm Identification Card covers rifles and shotguns. Assault weapons and magazines over 10 rounds are banned. A safety course is mandatory.
Security Deposits and Tenant Protections
Massachusetts limits security deposits to one month's rent, which must be held in an interest-bearing account. Treble damages for landlord non-compliance. 14-day notice for non-payment eviction. Strong anti-retaliation protections. Statewide rent control was repealed in 1994.
Consumer Protection Act (Chapter 93A)
Massachusetts's Chapter 93A is one of America's strongest consumer protection laws. Consumers must send a 30-day demand letter before suing. Successful claims yield actual damages or $25 plus attorney's fees, with double or triple damages for willful violations. Class actions are authorized.
Assault and Battery
Massachusetts charges assault and battery together (A&B). Simple A&B is a misdemeanor with up to 2.5 years jail and $1,000 fine. Enhanced penalties apply for A&B on family members, dating partners, pregnant women, the elderly, or with a weapon — many becoming felonies.
Assault and Battery with a Dangerous Weapon
Massachusetts assault and battery with a dangerous weapon (which can include common objects used in dangerous ways) is a felony with up to 10 years state prison. Causing serious bodily injury raises the maximum to 15 years. Victim status (child, pregnant, elderly) adds enhancements.
Possession of Controlled Substances
Massachusetts schedules drugs Class A (most serious) through E. Marijuana is legal for adults 21+ (up to 1 oz public, 10 oz home). Class A and B drug possession (heroin, cocaine) brings up to 1 year jail. Trafficking carries enhanced felony penalties. CWOF available for first offenders.
Larceny
Massachusetts uses the term 'larceny' rather than theft. Larceny under $1,200 is a misdemeanor (up to 1 year, $300 fine); over $1,200 is a felony (up to 5 years prison). The threshold was raised from $250 to $1,200 in 2018. Stealing firearms or from elderly/disabled persons is enhanced.
Grounds for Divorce
Massachusetts allows both no-fault (irretrievable breakdown) and fault divorces. Section 1A joint petitions with full agreement become absolute after 90 days; Section 1B contested cases proceed alone. One spouse must have a year's residency. Property is divided equitably.
Care, Custody, and Maintenance of Children
Massachusetts custody decisions follow the best interest of the child. Massachusetts presumes shared legal custody pending divorce but not shared physical custody. Courts examine parental cooperation, caregiving history, child's adjustment, and any abuse history.
Child Support Guidelines
Massachusetts calculates child support using income-shares guidelines. Support typically lasts until age 18, but may extend to 21 if the child lives with and depends on a parent, or to 23 if in undergraduate education. Failure to pay can lead to license suspension and tax intercepts.
Minimum Wage
Massachusetts minimum wage is $15.00/hour as of January 2023, phased in from $11. Tipped workers earn $6.75 plus tips (employer makes up difference). Massachusetts uses a strict ABC test for employee classification, making misclassification as contractors difficult.
At-Will Employment
Massachusetts is at-will but offers strong protections through Chapter 151B, banning discrimination by race, sex, sexual orientation, gender identity, age, disability, criminal record, and many other protected traits. Public policy and contract exceptions also apply.
Paid Family and Medical Leave Program
Massachusetts's PFML program provides up to 20 weeks of paid medical leave, 12 weeks paid family leave (or 26 for injured service member care), funded by payroll contributions. Benefits replace ~80% of wages up to $1,170.64/week (2025). Employers with 25+ employees pay both shares.
Security Deposits
Massachusetts caps security deposits at one month's rent. Landlords must hold deposits in separate interest-bearing accounts (5% or actual rate), provide written receipts and annual statements, and return deposits with itemized deductions in 30 days. Violations forfeit retention rights and trigger triple damages.
Summary Process Eviction
Massachusetts eviction (Summary Process) requires 14-day Notice to Quit for nonpayment in at-will tenancies. Tenants can cure within 10 days (once per 12 months). Cases include answers and counterclaims. Self-help evictions trigger damages of 3 months' rent plus attorney's fees.
Certificate of Organization
Massachusetts LLCs are formed by filing a Certificate of Organization for $500 — among the highest fees in the U.S. Annual reports also cost $500. Names must include 'LLC' or similar designation. Operating agreements are recommended but not required.
Massachusetts Lemon Law
Massachusetts has one of America's strongest Lemon Laws covering both new and used vehicles. New vehicle protection: 1 year or 15,000 miles, with 3 repair attempts or 15 business days triggering a refund/replacement. Used vehicles get 30-90 day warranties from dealers.
Distribution Without a Will
Massachusetts adopted the Uniform Probate Code in 2012. Spouses inherit everything if no descendants or all descendants are shared. With stepchildren, the spouse gets $100,000 plus half. With parents but no descendants, the spouse gets $200,000 plus three-fourths.
Execution of Wills
Massachusetts wills must be written, signed by the testator, and witnessed by two individuals (under the MUPC). Holographic wills generally aren't valid in Massachusetts. Self-proving wills with notarized affidavits speed up probate.
Speed Restrictions
Massachusetts has 65 mph on most interstates (some at 55), 40 mph default rural, 30 mph in thickly settled areas, and 25 mph in school zones. Speeding fines add $10 per mph over the limit, plus a $50 base and surcharges. Excessive speeding may be criminal reckless operation.
Small Claims Procedure
Massachusetts small claims handles disputes up to $7,000 (no cap for vehicle damage) with simplified rules. Hearings happen within 30-60 days. Plaintiffs can't appeal losses, but defendants can appeal within 10 days for a District Court jury trial.
