Which amendment is known for addressing the issue of due process?

The Fifth Amendment is known for addressing the issue of due process because it explicitly includes a provision that guarantees fair treatment through the judicial system. This amendment states that no person shall be "deprived of life, liberty, or property without due process of law." This means that the government must follow established legal procedures when it seeks to take away an individual's rights. The concept of due process serves as a fundamental protection against arbitrary action and is essential for ensuring justice and fairness in legal proceedings.

While other amendments, like the Fourteenth Amendment (not listed among the choices), also address due process, the Fifth Amendment is often highlighted for its significant role in federal law. The First Amendment focuses on the freedoms of speech, religion, and assembly; the Twelfth Amendment deals with the procedures for electing the President and Vice President; and the Ninth Amendment asserts that the enumeration of certain rights in the Constitution does not mean that other rights do not exist. Therefore, the focus of the Fifth Amendment on due process makes it the correct answer to the question.
