Miranda waiver
A defendant's relinquishment of Fifth Amendment rights after receiving proper warnings during custodial interrogation.
Full Definition
The voluntary, knowing, and intelligent decision by a suspect to waive their constitutional rights against self-incrimination and to counsel during custodial interrogation, following receipt of Miranda warnings. The validity of a Miranda waiver is often challenged in court, particularly when the defendant has mental illness, intellectual disability, or substance impairment that may affect their understanding or decision-making capacity. Forensic mental health evaluations may be requested to assess whether a defendant had the cognitive and volitional capacity to make a valid waiver decision, considering factors such as mental state, understanding of rights, and appreciation of consequences.
Usage
Usage note: Forensic evaluations may assess capacity to make valid waiver decision, particularly with mental illness.
