The US President, George W Bush, has refused to rule out military tribunals for inmates at Guantanamo Bay detention centre.
The US Supreme Court yesterday ruled that Mr Bush had over-stepped his authority in setting up the tribunals.
It ruled that the tribunals violated the Geneva Conventions and the US military code of justice.
The ruling came in a case brought by Osama Bin Laden's ex-driver, Salim Ahmed Hamdan, who had challenged the rules specified for his trial.
Speaking on RTÉ Radio's Morning Ireland, Mr Hamdan's lawyer, Lt Commander Charles Swift, said there was no reason why the 'war on terror' could not be pursued in accordance with the rules of the Geneva Convention.
The US government has insisted that there is no question of releasing detainees.
Preliminary comments have signalled that the administration plans to seek legislation to introduce a new version of the tribunals.
