Which amendment guarantees a criminal defendant the right to an impartial jury?

The Sixth Amendment is the one that guarantees a criminal defendant the right to an impartial jury. This amendment is part of the Bill of Rights and provides several protections for individuals accused of crimes. Specifically, it ensures that the trial is conducted fairly and that the jury is composed of individuals who do not have biases or preconceived notions about the case at hand.

The right to an impartial jury is crucial because it upholds the principle of due process, which is essential for maintaining the integrity of the judicial system. An impartial jury helps ensure that verdicts are based on the facts presented during the trial rather than on external influences or prejudices.

Other amendments mentioned address different rights and protections. The Fifth Amendment, for example, includes provisions related to self-incrimination and double jeopardy but does not specifically mention jury composition. The Eighth Amendment focuses on protection against excessive bail, fines, and cruel and unusual punishments, while the Fourteenth Amendment addresses broader issues of citizenship and equal protection under the law but does not specifically guarantee rights related to jury impartiality in criminal cases. Thus, the Sixth Amendment is the correct answer for the guarantee of an impartial jury for criminal defendants.
