Which amendment addresses the right to trial by jury?

The Seventh Amendment of the United States Constitution explicitly addresses the right to trial by jury in civil cases. It guarantees that in suits at common law, where the value in controversy exceeds twenty dollars, the right to a jury trial shall be preserved. This amendment reflects a fundamental principle of fairness in the legal system, ensuring that individuals have the opportunity to have their cases decided by a group of their peers rather than solely by a judge. The inclusion of this right underscores the importance of an impartial jury in maintaining justice and protecting citizens' rights within the legal framework.

The other amendments mentioned do not pertain to the right to trial by jury. The Second Amendment deals with the right to keep and bear arms, the Ninth Amendment concerns the enumeration of rights and emphasizes that the listing of certain rights does not deny or disparage other rights retained by the people, while the Tenth Amendment addresses the powers not delegated to the federal government being reserved to the states or the people. Each of these amendments serves distinct purposes, emphasizing different aspects of rights and governance, hence they do not relate to the trial by jury.
