The Supreme Judicial Court was established in 1692.

King William III (William of Orange) and Queen Mary II assumed the throne of England in 1688, an event known to us as the "Glorious Revolution." At this time, the colony of Massachusetts Bay had been without a charter for five years, as the previous charter had been revoked by King James II due to the colony's violating trade restrictions imposed by England and exhibiting religious intolerance toward members of the Anglican Church. In 1691, at the urging of Reverend Increase Mather, Rector of Harvard and Pastor of Second Church in Boston, King William and Queen Mary issued a charter which established the Province of Massachusetts. Known as the Second Charter, it authorized the provincial government to "erect and constitute judicatories and courts of record . . ." During the spring of 1692, as witchcraft hysteria gripped Salem and its environs, Colonial Governor William Phips appointed a special Court of Oyer and Terminer to hear and determine charges of witchcraft within the counties of Essex, Middlesex, and Suffolk. This Court permitted "spectral evidence," the testimony of an allegedly afflicted person that the accused had appeared in the form of an apparition. Between June 2 and October 29, 1692, the Court of Oyer and Terminer sentenced twenty people to death. This Court was dissolved at the end of October, 1692, but several dozen people remained in prison, awaiting trial on the charge of witchcraft.

On November 25, 1692, the General Court passed legislation creating the Superior Court of Judicature and various lower courts. The five Justices of the newly-established Superior Court of Judicature sat for the first time on January 3, 1693, in Salem. The new Court, which ignored spectral evidence as unreliable, heard the cases of twenty-six persons accused of witchcraft; twenty-three were found not guilty and the remaining three were later pardoned by the Governor.

The Superior Court of Judicature was a trial and appellate court; the court had original jurisdiction over felony prosecutions, and appeals consisted of trials de novo (a new trial with evidence).

The Superior Court of Judicature played an important role in this nation's struggle for independence. In 1761, the Court decided the "Writs of Assistance" case, one of the most important cases heard in colonial America. In that case, Boston attorney James Otis argued that the writs - general warrants that allowed officials to search for smuggled material within any suspected premises - violated man's inherent and inalienable rights. Though the court upheld the writs, Otis's argument galvanized the colonists. John Adams, who witnessed Otis's argument, wrote, "then and there, the child Independence was born."

In 1775, after the battles of Lexington and Concord, the Massachusetts Revolutionary Council took over the colony's government and removed the justices of the Superior Court of Judicature. The Council replaced four of the five justices who had been appointed by the Royal Governor with revolutionary sympathizers, including John Adams, who was appointed as Chief Justice. 2  In 1780, the Constitution of the Commonwealth of Massachusetts went into effect and the Superior Court of Judicature was given a new name: the Supreme Judicial Court of Massachusetts. The Massachusetts Constitution proclaims the centrality of judicial independence in Article 29:

It is essential to the preservation of the rights of every individual, his life, liberty, property, and character, that there be an impartial interpretation of the laws, and administration of justice. It is the right of every citizen to be tried by judges as free, impartial, and independent as the lot of humanity will admit. It is, therefore, not only the best policy, but for the security of the rights of the people, and of every citizen, that the judges of the supreme judicial court should hold their offices as long as they behave themselves well, and that they should have honorable salaries ascertained and established by standing laws.

In February, 1781, Governor Hancock formally appointed the five justices serving on the Superior Court of Judicature as justices of the Supreme Judicial Court.3  A year later the legislature specified that the court consist of a Chief Justice and four other justices, and that "each... shall be an Inhabitant of this Commonwealth, of Sobriety of Manners, and learned in the Law." In 1800, the legislature increased the number of justices from five to seven. Between 1804 and 1873, the legislature changed the number of justices seven times, though the number of justices never went below four or above seven. Since 1873, the number of justices has remained at seven.  

Over time, as the appellate caseload grew, the Supreme Judicial Court gradually relinquished its trial court jurisdiction. The legislature removed the court's original (trial) jurisdiction over tort cases in 1880 and over capital (murder) cases in 1891. The Appeals Court was created in 1972 to relieve the appellate burden on the Supreme Judicial Court.
