Which article of the U.S. Constitution refers to the right of trial by jury?

The reference to the right of trial by jury is found in Article 3, Section 2 of the U.S. Constitution. This section establishes the judicial power of the United States and clearly states that the trial of all crimes, except in cases of impeachment, shall be by jury. This right is fundamental to providing fair legal proceedings, ensuring that an individual's case is evaluated by a group of peers rather than solely by a judge or government authority. The significance of the jury trial in the U.S. legal system stems from the principle of having civilians involved in the justice process, which helps safeguard against potential government overreach and protects individual rights. The other articles mentioned do not contain provisions pertaining to the right to a jury trial, making the third option the accurate choice.
