Tenn. R. Juv. P. 207
Advisory Commission Comments.
There are no reported cases in Tennessee addressing the question of whether or under what circumstances an insanity defense is available in juvenile court proceedings. Application of this defense in juvenile proceedings has been recognized in various jurisdictions. See, e.g. In re Two Minor Children, 592 P.2d 166 (Nev. 1979); State ex rel. Causey, 363 So. 2d 472 (La. 1978); Winburn v. State, 145 N.W.2d 178 (Wis. 1966); see also In re Ramon M., 584 P.2d 524 (Cal. 1978); and State v. Ferrell, 209 S.W.2d 642 (Tex. Civ. App. 1948). The leading case holding the insanity defense inapplicable to delinquency proceedings, In re H.C., 256 A.2d 322 (N.J. 1969), was subsequently held to be overridden by modifications of the New Jersey Juvenile Court Act. In re R.G.W., 342 A.2d 869 (N.J. 1975), aff?'d, 358 A.2d 473 (N.J. 1976). However, at least one jurisdiction continues to preclude the insanity defense from being asserted at the adjudicatory hearing (although recognizing the claim of incompetence to stand trial). See In re C.W.M., 407 A.2d 617 (D.C. 1979); see also Golden v. State, 21 S.W.3d 801 (Ark. 2000).
This rule is not intended to alter the substantive law respecting the applicability of the insanity defense to juvenile court proceedings in Tennessee or to delineate those circumstances under which such a defense may be available. Rather, it provides procedures for those cases in which "the child intends to introduce expert testimony relating to mental disease, defect or other condition bearing upon the issue of whether the child had the mental state required for the offense charged."
The 2016 amendment was drafted to articulate a clear difference between a finding of incompetency by the court and an affirmative defense of diminished capacity. In addition, the rule clarifies that a child's statements made during an evaluation of their competency shall not be used against them in court as an admission of guilt.
Rule 110 provides that in a delinquency proceeding the computation of time shall toll during the period in which the child is found to be incompetent to stand trial.
