Md. R. Evid. 5-704
Section (a) of this Rule is derived from F.R.Ev. 704(a). Section (b) is new.
Committee note: Section (b) of this Rule is substantively different than F.R.Ev. 704(b). The Federal provision precludes an opinion on the ultimate issue of criminal responsibility, i.e., sanity. The Maryland Rule does not preclude such an opinion. It does, however, preclude an opinion as to whether the defendant had a required intent or mental state where that intent or state is an element of the offense. See Hartless v. State, 327 Md. 558 (1992).
