A citizen’s right to a trial by jury is a central feature of the United States Constitution. It is considered a fundamental principle of the American legal system. Laws and regulations governing jury selection and conviction/acquittal requirements vary from state to state (and are not available in courts of American Samoa), but the fundamental right itself is mentioned five times in the Constitution: Once in the original text (Article III, Section 2) and four times in the Bill of Rights (in the Fifth, the Sixth, and the Seventh Amendments).
