In sei contro le leggi anti terrorismo
Six challenging anti-terror laws
Six people arrested over the dissident republican murders of two soldiers and a policeman have launched a new High Court challenge to anti-terror laws.
The suspects have already won a legal case against a decision to extend their period in custody.
But they want a declaration that the relevant legislation was incompatible with their right to liberty under the European Convention on Human Rights.
Only one of the six – Colin Duffy – was charged after they were questioned.
He is accused of the murders of Sappers Mark Quinsey and Patrick Azimkar at Massereene barracks in Antrim on 7 March.
Three of the others were questioned over those murders, while two were questioned about the murder of Constable Stephen Carroll in Craigavon, County Armagh, two days later.
None of these five can be identified after they were granted anonymity by judges hearing the case.
Proceedings began earlier this year when a County Court judge granted police more time to question all six under the amended Terrorism Act which allows for suspects to be held for up to 28 days before they must be charged or released.
Although this extension was quashed, a further claim that it breached their European Convention rights was set aside at the time due to the urgency of the case.
Lawyers for Duffy and the others returned to the High Court on Monday to request the declaration.
