The 24-year-old, from Emmett Road, Inchicore, Dublin, is serving an eight year jail term for assault on Nigel Reid, who was out walking his dog when attacked by Dumbrell. Reid lost the sight of his left eye in the attack.
Barrister Iseult O’Malley, counsel for Dumbrell, told Mr Justice Michael Peart in the High Court yesterday that Leroy had been detained in solitary confinement for the past five months and looked as if he was going to be kept there.
Ms O’Malley said she would be seeking leave to judicially review the decision of the Castlerea Prison governor to keep Dumbrell in solitary confinement.
She told the court she would also be making an application under Article 40 of the Constitution seeking Dumbrell’s release from prison on the grounds of his continuing solitary confinement.
Mr Reme Farrell, counsel for the Governor, told Judge Peart there was a possibility the issue regarding the judicial review matter may be capable of resolution in that it related to Dumbrell’s return to the general prison population.
The Article 40 issue, in which the only remedy would be Dumbrell’s release, was a different matter and he was seeking a short adjournment to facilitate the preparation of an affidavit by the prison governor.
Judge Peart adjourned both applications until Friday next.
Two weeks ago Warren, 32, and Jeffrey, 26, succeeded in their appeal against their convictions for the murder of father-of-six Christopher Cawley by stabbing him to death.
The Court of Criminal Appeal held that a speech made by the murder case trial judge, Mr Justice Paul Carney, during the trial could have been prejudicial to a fair trial and could have had an influence on the jury.
