Which amendment guarantees the right to a jury trial in civil cases?

The Seventh Amendment is the correct answer because it specifically addresses the right to a jury trial in civil cases. It states 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 ensures that individuals have the option to have their civil disputes decided by a jury of their peers, reflecting the value placed on this type of adjudication in the American legal system.

The Sixth Amendment, on the other hand, pertains to criminal cases and guarantees the rights of individuals charged with crimes, including the right to a jury trial, but only in criminal proceedings. The Eighth Amendment deals with excessive bail and cruel and unusual punishment, which is unrelated to the civil trial context. Lastly, the Ninth Amendment addresses the protection of rights not specifically enumerated in the Constitution, without referring to the right to a jury trial in civil cases. Therefore, the Seventh Amendment is the only one that guarantees this specific right in civil litigation.
