Colm Murphy, who is awaiting a retrial for offences connected with the Omagh bombing in 1998, had the terms of his bail varied by the Special Criminal Court in Dublin yesterday.
Murphy was freed on bail last January after the Court of Criminal Appeal quashed his conviction for conspiracy offences connected with the "Real IRA" bombing.
Twenty-nine people, including a woman who was pregnant with twins, were killed and more than 300 people were injured in the bombing.
Mr Murphy was freed after he signed a bail bond, lodged €50,000 in cash with the court, agreed to sign on daily at Dundalk Garda station, to live at Plaster, Mountpleasant, Dundalk, Co Louth, and not to apply for a passport.
His solicitor Michael Farrell yesterday applied to have the daily signing-on condition varied to three times a week.
Mr Farrell said his client had observed the terms of his bail.
His case was listed for next October, but there was another trial which had a bearing on the case scheduled for December, and Mr Murphy was unlikely to get a new trial before January next year.
Mr Justice Richard Johnson said that, with the consent of the State, the court would vary the bail conditions.
