A fair trial is a trial which is "conducted fairly, justly, and with procedural regularity by an impartial judge". Various rights associated with a fair trial are explicitly proclaimed in Article 10 of the Universal Declaration of Human Rights, the Sixth Amendment to the United States Constitution, and Article 6 of the European Convention of Human Rights, as well as numerous other constitutions and declarations throughout the world. There is no binding international law that defines what is not a fair trial; for example, the right to a jury trial and other important procedures vary from nation to nation.
