State v. Maday
In State v. Maday, 179 Wis. 2d 346, 507 N.W.2d 365 (Ct. App. 1993), the Court held that a defendant charged with sexual assault is entitled to a psychological examination of the victim when the State's expert witnesses conduct psychological examinations and the State intends to rely on evidence produced by those examinations. See id. at 349.
The Court remarked that "a defendant who is prevented from presenting testimony from an examining expert when the state is able to present such testimony is deprived of a level playing field." Id. at 357.
