In Ake v. Oklahoma, 470 U.S. 68, 84 L. Ed. 2d 53, 105 S. Ct. 1087 (1985), the United States Supreme Court held that when a defendant demonstrates to the trial judge that his sanity at the time of the offense is to be a significant factor at trial, the State must, at a minimum, assure the defendant access to a competent psychiatrist who will conduct an appropriate examination and assist in evaluation, preparation, and presentation of the defense. Id. at 83.
