Regina v Maguire: CACD 1992

The defendant, convicted of murder, had died. It later came to light that materials with the prosecution forensic team had not been disclosed by the prosecution.
Held: The Home Secretary could make a reference to the Appeal court despite the death. Such a failure could be a material procedural irregularity. The duty of disclosure on a prosecutor extended also to the prosecutors forensic experts.
A material irregularity which causes a conviction to be quashed is not a mere procedural irregularity and there is no real distinction between a material irregularity which causes a miscarriage of justice and a feature of the trial which causes a conviction to be unsafe: ‘The outcome of the debate as to whether non-disclosure of material is an irregularity within ground (c) or is a feature which can render a conviction unsafe or unsatisfactory under ground (a) has, as it seems to us, no consequence in regard to the result (as opposed to the route) of an appeal. This is because of the proviso. If the court is unable to hold ‘that no miscarriage of justice has actually occurred’ in a case of irregularity then, as in Regina v. Paraskeva, 76 Cr.App.R. 162, the conviction is not ‘safe’. If it does so hold, then the court is effectively saying that the conviction is safe and satisfactory.’
