A legal expert has said she believes that the three Irishmen convicted of terrorism offences in Colombia may have no case to answer under Irish law.
The Tánaiste, Mary Harney, had earlier called on Niall Connolly, Martin McCauley and James Monaghan to make themselves available to gardaí.
Ms Harney said it was an offence for someone to travel on fraudulently-obtained documentation.
However, the director of the Council for Civil Liberties, Aisling Reidy, has said gardaí would have to have evidence that someone possessed a false document in Ireland before officers would want to talk to that person.
She also doubted that the sentence the men were given for training FARC rebels could be transferred to Ireland under a bill that is not yet law, as suggested in some reports.
Ms Reidy said even if the legislation was allowed to be applied retrospectively, the question was then what would be the offence in Ireland which would be equivalent to that in Colombia.
The men have been on the run from the authorities in Colombia since December 2004 when they were released on bail awaiting a court of appeal decision.
An international arrest warrant was issued for the men who were also found guilty of travelling on false passports.
The authorities in Colombia had not yet officially requested the extradition of the three Irishmen.
