Reciprocal discovery
In criminal procedure, reciprocal discovery refers to the exchange of documents, lists of witnesses, and other information between the two sides of a lawsuit or criminal prosecution before trial.
Particularly in the United States criminal law context, the Federal government and certain states have reciprocal discovery laws which compel defendants to disclose some information to prosecutors before trial.[1] Material disclosed in this fashion is referred to as reverse Jencks material, after the U.S. Supreme Court decision that established the principle, Jencks v. United States.
