The Court of Appeal has dismissed appeals by two men challenging their surrender to Northern Ireland to stand trial over alleged offences dating back about 50 years.
John Edward Anthony McNicholl and Séamus Christopher O’Kane had appealed High Court decisions ordering their surrender under Trade and Cooperation Agreement arrest warrants issued in Belfast in April 2024.
McNicholl is accused of murdering Constable Robert McPherson and attempting to murder Constable William Elliott during a shooting at Dungiven, County Londonderry, on July 26, 1975. He is also accused of four offences involving explosives, firearms and ammunition allegedly found at Garvagh on February 16, 1976.
O’Kane’s current warrant concerns four alleged explosives, firearms and ammunition offences arising from the Garvagh search. Both men contest the allegations and the Court of Appeal was not determining their guilt.
The central issue was whether the extraordinary passage of time, including lengthy periods when Northern Ireland authorities did not pursue surrender, made the present applications an abuse of the Irish courts’ process or otherwise required surrender to be refused.
Mr Justice Alexander Owens said there were significant periods of inaction after 2004 and concluded that some of the delay was difficult to explain and could have resulted from maladministration. However, delay or maladministration alone was not a permissible stand-alone reason to refuse surrender.
The court held that delay must instead be considered through recognised fundamental-rights protections, including proportionality and family-life rights. It found that neither man had shown health, family or other circumstances sufficient to outweigh the strong public interest in bringing people accused of very serious offences to trial.
The court also rejected O’Kane’s argument that a 1978 High Court decision preventing his extradition under the then-existing political-offence rules gave him continuing immunity from surrender for the Garvagh allegations.
Both appeals were dismissed. The Court of Appeal said appropriate orders should be made to secure their surrender in accordance with the High Court orders of June 4, 2025. Questions about guilt and any trial-related consequences of the delay remain for the Northern Ireland courts.
