Criminal Defense Laws in Massachusetts

Criminal Defense Law in Massachusetts: Overview

Massachusetts takes a progressive approach to criminal justice while maintaining strict penalties for serious offenses. The state uses the term OUI (Operating Under the Influence) rather than DUI or DWI, and imposes escalating penalties for repeat offenders. Massachusetts legalized recreational marijuana in 2016 and has one of the more developed expungement frameworks in New England. The state abolished the death penalty in 1984 and does not have a three-strikes law in the traditional sense, though habitual offender statutes allow enhanced sentencing. Massachusetts follows the duty to retreat doctrine in public spaces but recognizes the castle doctrine inside the home. The state undertook significant bail reform in 2018 to reduce pretrial detention of individuals who cannot afford cash bail. Felonies and misdemeanors are classified by the court in which they are tried rather than a lettered grading system.

Key Statutes & Deadlines

OUI Lookback Period and Penalties

Massachusetts uses a lifetime lookback period for OUI offenses, meaning all prior OUI convictions regardless of when they occurred count toward enhanced penalties. A first offense can result in up to 2.5 years in jail and a one-year license suspension, though first offenders often qualify for a 24D disposition involving probation and an alcohol education program. A second offense carries a mandatory minimum 60 days in jail and a two-year license suspension. Third and subsequent offenses are felonies with mandatory minimum prison sentences. A third offense carries 180 days minimum and up to 5 years in state prison. A fifth or subsequent offense is punishable by up to 10 years in state prison with a mandatory minimum of 24 months. The legal BAC limit is 0.08% for adults and 0.02% for drivers under 21.

Duty to Retreat and Castle Doctrine

Massachusetts follows the duty to retreat doctrine in public spaces, meaning a person must attempt to retreat before using deadly force in self-defense, provided retreat can be accomplished safely. However, the state recognizes a strong castle doctrine. Under Massachusetts common law and as affirmed in Commonwealth v. Shaffer (1975), individuals have no duty to retreat when they are in their own home and are confronted with a threat of serious bodily harm or death. The castle doctrine extends to occupied dwellings but does not apply to common areas of apartment buildings or to motor vehicles. Massachusetts does not have a statutory stand your ground law, and the duty to retreat applies in all locations outside the home.

Marijuana Legalization and Remaining Penalties

Massachusetts legalized recreational marijuana for adults 21 and over in 2016 through a ballot initiative. Adults may possess up to one ounce in public and up to ten ounces at home, and may cultivate up to six plants per person or twelve per household. Possession of more than one ounce but less than two ounces in public is a civil infraction punishable by a $100 fine. Possession with intent to distribute remains a criminal offense carrying up to 2 years in jail for amounts under 50 pounds. The Cannabis Control Commission oversees the licensed retail market. Individuals with prior marijuana convictions that would no longer be criminal may petition for expungement under M.G.L. ch. 276, § 100K.

Massachusetts Court System

Massachusetts criminal cases are divided between the District Courts and the Superior Courts. District Courts handle misdemeanors and felonies punishable by up to 2.5 years in the house of correction. Superior Courts have jurisdiction over all felonies and exclusive jurisdiction over crimes punishable by state prison sentences exceeding 2.5 years, including murder. Juvenile offenders are handled in the Juvenile Court Division. The Boston Municipal Court operates similarly to the District Courts for the city of Boston. Appeals from District Court go to the Appeals Court, and appeals from Superior Court may go directly to the Appeals Court or the Supreme Judicial Court. The Supreme Judicial Court is the highest court in the state.

Damages & Penalties

Massachusetts classifies crimes based on the court in which they are tried rather than a lettered felony class system. Crimes punishable by incarceration in the state prison (sentences over 2.5 years) are felonies, while crimes punishable by up to 2.5 years in the house of correction are misdemeanors. Murder in the first degree carries a mandatory life sentence without parole. Armed robbery carries up to life in state prison. Drug trafficking sentences vary by substance and weight, with mandatory minimums ranging from 3.5 years to 20 years. Massachusetts has eliminated many mandatory minimum sentences for drug offenses through recent reforms, including the 2018 Criminal Justice Reform Act, which removed mandatory minimums for several drug possession offenses and reduced penalties for nonviolent crimes.

Recent Legislative Changes

The 2018 Criminal Justice Reform Act (Ch. 69 of the Acts of 2018) was the most sweeping criminal justice overhaul in Massachusetts in decades. It raised the felony larceny threshold from $250 to $1,200, reduced penalties for nonviolent offenses, expanded diversion programs, and reformed the bail system to require judges to consider a defendant's ability to pay. The act also created a more accessible expungement process and mandated that juvenile records be sealed more readily. In 2022, the Supreme Judicial Court ruled in Commonwealth v. Daveiga that certain immigration consequences must be considered during plea negotiations. Massachusetts continues to expand decriminalization efforts and invest in alternatives to incarceration.
