One of the 'Hooded Men' has said the British Supreme Court must rule that they were tortured if it hears an appeal to a judgment handed down in Belfast earlier this year.
The majority ruling came following an appeal by the PSNI chief constable against a previous High Court judgment that the PSNI must investigate the unlawful treatment of the men.
In the majority ruling, two of the three judges found they were satisfied that the treatment "would if it occurred today properly be characterised as torture".
Speaking on RTE's Ray D'Arcy Show, Francis McGuigan asked what is different today, saying "it was torture then and it is torture today".
The Irish government took a case to Europe on behalf of the men in the 1970s, with the European Commission of Human Rights finding in 1976 that they were subjected to torture.
However, the British government appealed that ruling to the European Court of Human Rights, who amended the judgment to one of "inhuman and degrading treatment".
The 14 men, who were all Catholics, were detained indefinitely without trial and said they were subjected to a number of torture methods.
These included five techniques, hooding, stress positions, white noise, sleep deprivation and deprivation of food and water, along with beatings and death threats.
The men were hooded and flown by helicopter to a secret location, later revealed as a British Army camp at Ballykelly, outside Derry.
Speaking on the same programme, Liam Shannon - another of the 'Hooded Men' - said they expect the PSNI to appeal the decision to the Supreme Court in London and they welcome that.
Mr Shannon said he remains "very angry" about the way he was treated, and the response to it.
"I want somebody to tell me why I was tortured, and somebody to just admit I was tortured," he said.
This torture wasn't just carried out by a bunch of squadies, or a bunch of RUC men who just thought they were going to beat some Paddies up. This was sanctioned at the very highest level."
Mr McGuigan said he is not interested in finding the men who carried out the interrogations, but rather in establishing which officials sanctioned it.
Like Mr Shannon, he welcomes any appeal to the Supreme Court.
"The Supreme Court in London must give the same verdict when they listen to what has happened to us," he said.
"That is going to make Europe look very foolish, when the highest court in the land that is accused says it is torture and Europe hasn't."
He said that other countries, such as the United States, Israel and Brazil, have relied on the European judgment to say that the use of similar techniques is not torture but rather "degrading and inhumane treatment".
Both men also told the programme that they continue to suffer with mental health issues as a result of their experiences.
The story of the Hooded Men will feature in the TG4 Finne documentary at 9.30pm tomorrow night.
