Nelson v. State
In Nelson v. State, 262 Ark. 391, 557 S.W.2d 191 (1977) "the prosecutor objected to the request on the ground that he had furnished appellant an opportunity to examine his files and the statement before trial."
The supreme court determined that:
It appears undisputed that a statement of the prosecuting witness existed and was in the possession of the prosecutor. A material and crucial issue in the case was the credibility of this witness in determining the guilt or innocence of the appellant. In the circumstances it was mandatory that the statement be furnished to the appellant for cross-examination purposes if it related to the subject matter about which the witness testified. Id. at 392, 557 S.W.2d at 192.
