The Miranda v. Arizona decision relates to which key principle?

The Miranda v. Arizona decision primarily relates to the principle of due process. This landmark Supreme Court case established that individuals taken into police custody must be informed of their rights to an attorney and against self-incrimination before being interrogated. The Court ruled that these rights are essential to ensure fair treatment and to protect individuals from coercion, thereby reinforcing the due process clause of the 14th Amendment.

This decision was pivotal in affirming that procedural protections must be in place to guarantee that individuals are aware of their legal rights, demonstrating how due process operates within the U.S. legal system to protect suspects during the criminal justice process. Understanding this principle is crucial for grasping how the legal system seeks to maintain fairness and justice for individuals facing potential criminal charges.
