Foucha v. Louisiana
JUSTICE O’CONNOR, concurring in part and concurring in the judgment.
Louisiana asserts that it may indefinitely confine Terry Foucha in a mental facility because, although not mentally ill, he might be dangerous to himself or to others if released. For the reasons given in Part II of the Court’s opinion, this contention should be rejected. I write separately, however, to emphasize that the Court’s opinion addresses only the specific statutory scheme before us, which broadly permits in definite confinement of sane insanity acquittees in psychiatric facilities. This case does not require us to pass judgment on more narrowly drawn laws that provide for detention of insanity acquittees, or on statutes that provide for punishment of persons who commit crimes while mentally ill.
I do not understand the Court to hold that Louisiana may never confine dangerous insanity acquittees after they regain mental health. Under Louisiana law, defendants who carry the burden of proving insanity by a preponderance of the evidence will “escape punishment,” but this affirmative defense becomes relevant only after the prosecution establishes beyond a reasonable doubt that the defendant committed criminal acts with the required level of criminal intent. State v. Marmillion, 339 So. 2d 788, 796 (La. 1976). Although insanity acquittees may not be incarcerated as criminals or penalized for asserting the insanity defense, see Jones v.
