Case law has established that criminal defendants have limited discovery rights. Many white collar criminals have based appeals on procedural rights to discovery. The operation of Rules 16 and 26.2 and the Jencks Act are discussed in detail, and, in addition, fifth amendment due process requirements relating to discovery are outlined. Of particular significance is a series of Supreme Court decisions, known as the Brady doctrine, that identifies the due process requirements of disclosure of exculpatory material in possession of the prosecution. It is alleged, however, that the Court has failed to provide clear guidance regarding the requirements of the Brady doctrine, thus eroding the due process guarantees of white collar defendants. 126 footnotes.
