Due process rights are legal guarantees that ensure fair treatment through the judicial system, protecting individuals from arbitrary deprivation of life, liberty, or property. These rights are primarily found in the Fifth and Fourteenth Amendments of the U.S. Constitution and establish the framework for both substantive and procedural fairness in legal proceedings. The concept is crucial in contexts involving military tribunals and enemy combatants, where the balance between national security and individual rights often comes into play.
