Final answer:
A "custodial interrogation" in the Code of Criminal Procedure of 1963 means questioning a suspect by law enforcement while the person is in custody or significantly deprived of freedom, requiring Miranda rights to be provided to protect against self-incrimination.
Step-by-step explanation:
According to the Code of Criminal Procedure of 1963, a "custodial interrogation" refers to the situation where a suspect is questioned by law enforcement officers while in custody or otherwise deprived of their freedom in a significant way.
This term gained prominence following landmark U.S. Supreme Court cases such as Miranda v. Arizona, which established that prosecutors could not use statements from a custodial interrogation unless they demonstrated the use of procedural safeguards to secure the privilege against self-incrimination. The suspects must be informed of their Miranda rights, including the right to remain silent, the right to consult with a lawyer, the right to have a lawyer appointed if they cannot afford one, and the right to terminate the interrogation at any time.
