Which court case established the need to inform suspects of their constitutional rights prior to interrogation?

The case that established the necessity to inform suspects of their constitutional rights prior to interrogation is Miranda v. Arizona. This landmark decision resulted in the formulation of what are commonly referred to as Miranda rights, which include the right to remain silent and the right to an attorney. These rights must be communicated to individuals taken into custody and interrogated by law enforcement to protect their Fifth Amendment privilege against self-incrimination.

The Supreme Court ruled that without informing suspects of these rights, any statements or confessions obtained during interrogation could be deemed inadmissible in court. This decision aimed to ensure that suspects are aware of their rights and to maintain the integrity of the judicial process by preventing coercive interrogation practices.

Other cases mentioned, while significant in the context of arrest and search procedures, do not specifically address the requirement to inform suspects of their rights before interrogation.
