Which Amendment is focused on due process?

The 14th Amendment is foundational to the concept of due process in the United States. Specifically, it prohibits states from depriving any person of life, liberty, or property, without due process of law. This amendment extends the protections of the Bill of Rights, which originally applied only to the federal government, and applies them to state actions as well.

This means that both substance and procedure must be fair and just when the government seeks to take away a person's rights. The 14th Amendment established a critical framework for protecting individuals from arbitrary actions by the state, ensuring that all legal proceedings are conducted fairly. The other amendments listed do address various rights and protections, but they do not focus on due process in the same way that the 14th Amendment does.
