Lawyers representing Stephen Silver, who is serving a 40-year sentence for the capital murder of Detective Garda Colm Horkan, have said they are unable to advance an appeal against his conviction as they have “hit a brick wall” in obtaining what they argue is crucial disclosure from the DPP relating to psychiatric evidence.

Speaking as the matter was raised during a review of dormant cases at the Court of Appeal on Monday, Mr John Edwards said it was “intolerable” that Det. Gda Horkan’s inquest has been delayed as a result of the pending proceedings. He said that the matter “cannot drag on”.
