Government of Massachusetts
The judiciary of Massachusetts is the branch of the government that interprets and applies the law of Massachusetts, ensures equal justice under law, and provides a mechanism for dispute resolution. The Massachusetts court system consists of the Supreme Judicial Court, the Appeals Court, and the seven Trial Court departments:The judicial power in Massachusetts is reposed in the Supreme Judicial Court, which superintends the entire system of courts. In addition to appellate functions, the Supreme Judicial Court is responsible for the general superintendence of the judiciary and of the bar, makes or approves rules for the operations of all the courts, and in certain instances, provides advisory opinions, upon request, to the Governor and Legislature on various legal issues. The Supreme Judicial Court also oversees several affiliated agencies of the judicial branch, including the Board of Bar Overseers, the Board of Bar Examiners, the Clients' Security Board, the Massachusetts Mental Health Legal Advisors Committee, and Massachusetts Correctional Legal Services.
Article Three of the United States Constitution
The Supreme Court is the only federal court that is explicitly established by the Constitution. During the Constitutional Convention, a proposal was made for the Supreme Court to be the only federal court, having both original jurisdiction and appellate jurisdiction. This proposal was rejected in favor of the provision that exists today. Under this provision, the Congress may create inferior (i.e., lower) courts under both Article III, Section 1, and Article I, Section 8. The Article III courts, which are also known as "constitutional courts", were first created by the Judiciary Act of 1789, and are the only courts with judicial power. Article I courts, which are also known as "legislative courts", consist of regulatory agencies, such as the United States Tax Court.
