Belfast's High Court has rejected two legal challenges to the UK's plan to leave the European Union.
Politicians from four of Northern Ireland's parties were involved in one of the actions.
The other was brought by Raymond McCord, who has campaigned on victims' rights issues since his son was murdered by loyalist paramilitaries.
Mr Justice Paul Maguire delivered his judgment this morning.
British Prime Minister Theresa May has welcomed the judgment.
Her spokesperson said there is no reason to think that the EU referendum undermines Britain's rock solid commitment to the 1998 Belfast agreement.
During three days of proceedings earlier this month, politicians from Sinn Féin, the SDLP, the Alliance Party and the Green Party suggested that the government could not trigger Article 50, the formal legal process for leaving the EU, without a parliamentary vote in Westminster.
