The term magistrate is used in a variety of systems of governments and laws to refer to a civilian officer who administers the law. In ancient Rome, a magistratus was one of the highest ranking government officers, and possessed both judicial and executive powers. In other parts of the world, such as China, a magistrate was responsible for administration over a particular geographic area. Today, in some jurisdictions, a magistrate is a judicial officer who hears cases in a lower court, and typically deals with more minor or preliminary matters. In other jurisdictions (e.g., England and Wales), magistrates are typically trained volunteers appointed to deal with criminal and civil matters in their local areas.
Magistrates are somewhat less common in the United States than in Europe, but the position does exist in some state jurisdictions and in federal courts.
As noted above, the terms "magistrate" or "chief magistrate" were sometimes used in the early days of the republic to refer to the President of the United States, as in President John Adams's message to the U.S. Senate upon the death of George Washington:
"His example is now complete, and it will teach wisdom and virtue to magistrates, citizens, and men, not only in the present age, but in future generations, as long as our history shall be read" (December 19, 1799).
