The Supreme Court has reserved judgement in a killer’s attempt to get damages for a 12-year delay in bringing his prosecution.
Mark Nash, who is originally from England, is serving a double life sentence for murdering two women in Grangegorman in Dublin in March 1997.
He was convicted last year while serving life sentences for murdering a couple in Co Roscommon five months later.
His lawyers claim his right to be tried within a reasonable time was breached because of a delay in charging him for the Grangegorman killings.
The five-judge panel will deliver its decision at a later date.
