'Intolerable' for garda's family to have impasse in Stephen Silver appeal 'drag on', judge says
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 Director of Public Prosecutions (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'.
Silver (48), a motorbike mechanic from Aughaward, Foxford, Co Mayo, had pleaded not guilty to the murder of Det Gda Horkan knowing or being reckless as to whether he was a member of An Garda Síochána acting in accordance with his duty.
He had pleaded guilty to manslaughter at Castlerea, Co Roscommon on June 17th, 2020, and the jury was told the main issue in the trial was Mr Silver's state of mind at the time of the shooting.
Silver, who killed Gda Horkan by shooting him eleven times with the garda's own gun, was jailed for life with a minimum time to be served of 40 years by a judge at the Central Criminal Court in April 2023.

The court heard Silver had suffered from bipolar affective disorder, though consultant psychiatrist Prof Harry Kennedy said he found 'no positive evidence' Silver had relapsed at the time he shot dead Det Horkan.
However Dr Brenda Wright, then interim clinical director at the Central Mental Hospital, told the court that Silver's illness contributed significantly to his actions at that time.
At the Court of Appeal on Monday, Morgan Shelley BL, representing Silver, said that this was, in effect, a diminished responsibility case and the psychiatric evidence was a 'critical issue'.
Mr Shelley said there was an issue in another case relating to one of the expert witnesses in Silver's trial and his legal team believe the Director of Public Prosecutions (DPP) may have materials that could be relevant to that. He said they have asked for 'comprehensive disclosure' from the DPP in relation to this but have 'hit a brick wall'.

'We may need this court to determine the issue, or we may need to go to another court for that,' he said.
Mr Justice John Edwards, presiding, said the coroner for County Mayo has written to inform the court that he cannot complete the inquest into Garda Horkan's death until the case is determined. He noted that Silver's appeal was last before the court in December 2023.
Mr Shelley remarked that a proper response from the DPP would assist in moving matters along.
Adjourning proceedings to a case management list on June 20th, Mr Justice Edwards told Mr Shelley that if there was a continuing 'log jam' then a motion could be brought before the court at that stage.

'This cannot drag on, particularly when there is an inquest and a family being prejudiced by this,' said the judge, describing the situation as 'intolerable'.
'This has to be addressed, and it will be addressed quickly from here on,' he added.
During the trial, the jury heard evidence from Silver that he believed Gda Horkan was 'a heavy down from Dublin' who was trying to kill him. He said that Gda Horkan, who was not in uniform and drove an unmarked car, was wearing a Tommy Hilfiger jacket and 'didn't come across' as a garda.
He gave evidence that a struggle ensued between them before he fell to the ground, and in the process of getting up he felt the gun on Gda Horkan's hip.

'I kept shooting until the gun finished and there was no ammunition left,' Silver said.
Silver's first trial ended in a jury disagreement. His defence at his second trial was that he could be found guilty of manslaughter either because he believed he was acting in self defence but used excessive force or because his responsibility was significantly diminished due to a mental disorder.
The jury rejected both defences and found him guilty of murdering Gda Horkan, a member of An Garda Siochana acting in the course of his duty. Under the Criminal Justice Act 1990, the judge must impose the ordinary life sentence for murder and specify that Silver serve a minimum of 40 years in prison.
With ordinary remission for good behaviour, Silver will be eligible to apply for parole after he has served 30 years.

Northern Ireland First Minister Michelle O'Neill calls on Ballymena attacks to stop
First Minister Michelle O'Neill has said attacks on families across Northern Ireland and rioting in Ballymena are "abhorrent and must stop immediately".Petrol bombs, masonry and fireworks were thrown at police on Tuesday night, in a second night of serious disorder the County Antrim town of disorder began on Monday after a peaceful protest over an alleged sexual assault in the County Antrim police officers have been injured. O'Neill said those responsible "bring nothing to our communities but hatred, fear and division".She added: "No-one, now or ever, should feel the need to place a sticker on their door to identify their ethnicity just to avoid being targeted."The Sinn Féin deputy leader said she had spoken to the chief constable "and urged him to ensure those responsible for orchestrating and perpetuating these crimes are held fully to account". Ministers appeal for calm In a joint statement, politicians in the Northern Ireland Executive appealed for statement on behalf of ministers from Sinn Féin, the Democratic Unionist Party (DUP), Alliance Party and the Ulster Unionist Party (UUP) said: "We strongly condemn the racially motivated violence witnessed in recent days and make an urgent appeal for calm across society"."The alleged serious sexual assault reported on 7 June in Ballymena was appalling and our collective thoughts are with the victim and their loved ones at this deeply traumatic time."It is paramount that the justice process is now allowed to take its course so that this heinous crime can be robustly investigated."Those weaponising the situation in order to sow racial tensions do not care about seeing justice and have nothing to offer their communities but division and disorder." DUP North Antrim assembly member Paul Frew said he fears someone will be killed in Ballymena if the violence said the disorder is "drowning out the strong and sincere sympathies for victims of sexual violence".The UUP said there is no justification for the "mayhem" that has happened over the last two nights and street violence is not a "legitimate" way to express concerns over the alleged sexual leader Mike Nesbitt said: "My thoughts are with those who have lost their homes and the greater number who are feeling intimidated and unwelcome."I also stand in solidarity with the blue lights, not just the PSNI but also the Fire and Rescue Service, who have had to deal with a number of house fires." 'Underlying tensions' Speaking to BBC Newsline on Tuesday, North Antrim MP Jim Allister said underlying tensions in Ballymena had been "there for a long time" because there was "an oversubscription of migrants who had been placed there".When asked about what evidence he was drawing on, the Traditional Unionist Voice (TUV) said the last time he canvassed a street in the area with 50 houses, he came "upon five local, if I can call them that, residents of Ballymena".After Tuesday night's violence, he posted on social media: "Tonight's further senseless violence in Ballymena is helping no cause, just destroying our own town and getting young men criminal records. Stop it."SDLP leader Claire Hanna responded by saying "some politicians are choosing to explain away" episodes of violence."We are hearing words of condemnation which are, at best insincere, and many people would describe as weaselly," she added."You can choose each day when you have a mandate and a platform to get up and try and solve problems or you can choose to exploit them, you can choose to try to calm tensions or you can try and fan them."Justice Minister Naomi Long said she was appalled by the "disturbing scenes", while Sinn Féin's Philip McGuigan, who represents the North Antrim constituency, appealed for calm and urged political leaders to "use measured language".
