The Court of Criminal Appeal has struck out an application by Real IRA leader Michael McKevitt to have his conviction for directing terrorism declared a miscarriage of justice.
In August 2003 McKevitt became the first person in the history of the State to be jailed for directing terrorist activities, while the 63-year-old has also been found liabel for the Omagh bombing.
The Appeal Court has dismissed the challenge, after the DPP argued it was "bound to fail."
