Amnesty International is warning that the clock is ticking for the European Court of Human Rights to address the hooded men torture case.
It involves the alleged ill-treatment of 14 men in Northern Ireland, who were arrested and quizzed about the IRA in 1971.
A European Court ruling in 1978 found that the five techniques of interrogation inflicted on the men did not constitute torture.
But new documents - revealed on an RTÉ programme in June - show the UK knowingly withheld crucial evidence from the court during the hearing.
The director of Amnesty Ireland, Colm O'Gorman, says they have written to both the Irish and UK governments urging them to act.
