sanity evaluation
Forensic assessment of a defendant's mental state at the time of the alleged offense to determine criminal responsibility.
Full Definition
A retrospective psychological evaluation that examines whether a defendant was legally sane at the time of the criminal act. The evaluation focuses on the defendant's mental condition during the offense, assessing whether they understood the nature and quality of their actions or knew that their conduct was wrong. This differs from competency evaluations which assess present mental state. The evaluation typically involves clinical interviews, psychological testing, review of records, and application of relevant legal standards.
Usage
Usage note: Also referred to as 'MSO' (mental state at time of offense) in some jurisdictions.
