Troubles victims' campaigner Raymond McCord appeared at the High Court in Belfast on Friday to legally block UK Prime Minister Boris Johnson from suspending the UK Parliament.
McCord is pursuing an injunction to block Johnson’s move ahead of the October 31 Brexit deadline.
"People say this happened before, but not for this length of time and not for the same reasons. This is a Prime Minister who will do anything to get his own way, without concern for the people of Northern Ireland or the peace process," he said.
The court has been adjourned until next week.
The five-week parliamentary break prompted by Johnson's decision would sharply curtail the opportunities for Members of Parliament to draft anti-no deal and anti-Brexit legislation with parliamentarians expected to sit for only a little over a week from September 3rd, and expected not to return until October 14 for the Queen's speech.
The move by Johnson was condemned as a "constitutional outrage" by the Speaker of the House of Commons, John Bercow, while Labour leader Jeremy Corbyn has said that his party will put forward legislation to prevent parliament being suspended.
A no-deal Brexit would have especially significant consequences for Northern Ireland as it would restore a strict border with Ireland, which could threaten the Northern Ireland peace process.
