Task: Wrong Candidate Generation
Input (English): discretion. Commonwealth v. Collins, 598 Pa. 397, 957 A.2d 237, 272 (2008). As noted, discovery in death penalty collateral proceedings is permissible only upon leave of court, and only for good cause shown. Pa.R.Crim.P. 902(E)(2). “ ‘A showing of good cause requires more than just a generic demand for potentially exculpatory evidence.’ ” Collins, 957 A.2d at 272 (quoting Commonwealth v. Bryant, 579 Pa. 119, 855 A.2d 726, 750 (2004)). We agree with the Commonwealth that Elliott has failed to demonstrate that the PCRA court abused its discretion by denying Elliott’s request for additional discovery. Elliott has not identified any document that was withheld from him that would have been exculpatory, and his claims to the contrary constitute mere speculation. See Hanible, 30 A.3d at 484 (<HOLDING>); Commonwealth v. Carson, 913 A.2d at 261 
 Holding statements: (A) holding lack of prejudice to the defendant is not good cause (B) holding that the government is not required to present exculpatory evidence to the grand jury (C) holding that record must show that evidence is exculpatory for defendant to establish brady violation (D) holding that speculation that production of requested documents might reveal exculpatory evidence is insufficient to establish good cause for discovery (E) holding that conjecture that opportunity to review homicide file might yield exculpatory evidence is inadequate to demonstrate good cause for discovery
Output (English): holding lack of prejudice to the defendant is not good cause
