A more thorough explanation: In legal terms, “lunacy” refers to a state of mental incapacity or insanity that renders a person unable to manage their own affairs or make rational decisions. It may be used in the context of legal proceedings related to mental health, such as determining a person’s competency to stand trial or managing their financial and personal affairs through a guardianship or conservatorship.
Example: The defendant’s claim of temporary insanity was dismissed by the court as mere lunacy.
