The family of Patrick Connors, who was found dead in a "pool of blood", plan to take legal advice on a potential challenge to a ruling against any retrial of his case.
In the family's home in Enniscorthy, Elizabeth Connors (73), said she has been left heartbroken as they feel they will never get justice for her son, Patrick (37).
Her son Gerry Connors (51) said the family felt the High Court ruling had left the family with "no choice" but to seek legal advice and try to take the matter further. "I feel very let down, there are two kids left without a father, I'm left without a son," Ms Connors told the Irish Independent.
"My children are without a brother and it's very very sad."
Ms Connors added: "I thought we were going to get some justice, so at least we would have had something to think about, but we'll never get over it at all now. It's going to be worse now.
"He was a lovely son, he was lovely, he was so gentle, and he was so good to his kids and good to his father and mother, all his sisters and brothers."
Mr Connors leaves behind two children, Chantelle (13) and Ann (7), who live with their mother.
"I think it's very sad to see Paddy's two children left there the way they are without a father," Ms Connors added.
The family said that the court's decision felt like "a blow" and that they felt like Mr Connors had died all over again.
"It feels even worse this time because this is reviewing everything again, when we might have got some closure on it but we didn't," Gerry Connors said.
