In People v. Tracey, 221 Mich App 321, 324; 561 NW2d 133 (1997), the Court identified three situations in which a defendant's due process rights to discovery were implicated. Specifically, due process was implicated where a prosecutor allowed false testimony to stand, where material evidence favorable to the defendant was suppressed, or where defendant made a general or no request for exculpatory information and exculpatory information was suppressed.
