Definition
The Supreme Judicial Court (SJC) is the name given to the highest court of the state in Massachusetts and Maine. In both states, it serves as the court of last resort for appeals from lower courts, with authority to resolve questions of state law, constitutional interpretation, and equity. The SJC is the oldest continuously operating appellate court in the Western Hemisphere, tracing its origins in Massachusetts to 1692.
In Massachusetts, the SJC consists of a Chief Justice and six Associate Justices. It exercises both appellate jurisdiction over decisions from the Appeals Court and direct appellate jurisdiction in certain matters, including cases involving the death penalty, life imprisonment, and the constitutionality of statutes. The court also has superintendence authority over all courts in the Massachusetts judicial system and governs the admission and discipline of attorneys in the state.
In Maine, the Supreme Judicial Court similarly serves as the court of last resort. Maine justices also sit as the Law Court when hearing appeals, a functional distinction that appears in Maine procedural law and older Maine sources.
The name is historical and distinctive. Most states use "Supreme Court" for their highest court. Massachusetts and Maine retained the older English-derived designation, making "Supreme Judicial Court" essentially a proper name for a specific institutional court rather than a generic descriptive term.
Common Confusion
The term is sometimes loosely used in historical sources to refer to any high appellate court with broad jurisdiction, but this usage is imprecise. In current American law, "Supreme Judicial Court" refers only to the highest courts of Massachusetts and Maine. Researchers encountering the phrase in older New Hampshire materials should note that New Hampshire also used this name historically; its highest court is now called the Supreme Court of New Hampshire, and the transition in nomenclature affects how sources index cases from that jurisdiction. Black's and Bouvier's both include New Hampshire in their definitions, which reflects the older usage and is no longer accurate for New Hampshire research.
Why It Matters in Research
The primary research trap is the New Hampshire problem. Both Black's and Bouvier's list New Hampshire alongside Massachusetts and Maine as states whose highest court bears this name. New Hampshire renamed its highest court, and researchers relying on these dictionary entries without verification may mislabel or misattribute sources. When working with New Hampshire appellate materials from the nineteenth century, confirm whether a given case was decided under the "Supreme Judicial Court" nomenclature or after the name change.
In Massachusetts, the SJC's dual role as appellate court and superintending authority over the bar creates a secondary research consideration: disciplinary decisions, bar admission rules, and court governance orders issued by the SJC are not judicial opinions in the conventional sense but carry binding authority. These materials are indexed separately from case law in many databases and may be missed in standard appellate research.
For Maine research, the Law Court designation adds an indexing wrinkle. When Maine justices convene as the Law Court, their decisions may appear under either label in older reporters and secondary sources. Researchers should not treat "Law Court" and "Supreme Judicial Court" as referring to different bodies—they are the same court in different procedural postures.
The SJC's age and prestige also mean it is disproportionately represented in early American common law development. Massachusetts SJC decisions from the late eighteenth and early nineteenth centuries are foundational in contract, tort, and property law across multiple jurisdictions. Researchers working on common law evolution should treat the SJC's historical record as a primary rather than peripheral source, even when the jurisdiction in dispute is not Massachusetts.
Historical Dictionary Support
Black's and Bouvier's are in complete agreement here, with Bouvier's entry appearing to track Black's nearly verbatim: both define the Supreme Judicial Court as an appellate tribunal and court of last resort in Maine, Massachusetts, and New Hampshire. Neither entry adds anything beyond this bare institutional identification. Neither source discusses the court's origins, internal structure, superintendence authority, or the Law Court designation in Maine.
The brevity is not a defect—both dictionaries treat this as a proper-name entry rather than a conceptual legal term, and the definition is accurate as far as it goes. The limitation is the New Hampshire inclusion, which was accurate when these editions were compiled but is no longer current. Researchers should treat the New Hampshire reference as historically bounded rather than operationally reliable.
Neither source engages with the SJC's significance as a legal institution or its role in shaping American common law. For that context, treatises on American legal history and the SJC's own published records are more useful than the dictionary entries.
Jurisdictional Note
The term "Supreme Judicial Court" is currently operative only in Massachusetts and Maine. In Massachusetts, the court also exercises original jurisdiction in certain extraordinary matters and governs attorney discipline statewide. In Maine, the same justices function as the Law Court when sitting in appellate review. All other U.S. states use different names for their highest courts, most commonly "Supreme Court."
