"There are two things that the high court said, well first of all was that the regional parliament in Northern Ireland didn't have the power to block an Article 50 trigger, however, it left open the question whether parliament behind us here in Westminster might be able to. But on the second issue, of whether triggering Article 50 was compatible with the Good Friday agreement, the court also ruled that the government could do that and that would be compatible with the peace process and the Good Friday agreement."

"I think the issues in Scotland are much more political and about a long running issue about Scottish independence, the Northern Irish issues around Brexit are going to be about exactly what form Brexit takes and therefore what logistical implications that has in terms of the border with the south, the common travel area with the south. So I think this case was actually quite specific. The bigger case that will be heard in the UK about Parliament's role in triggering article 50 is a more fundamental one and we'll have to wait and see what happens."

A judge in Northern Ireland has dismissed a legal challenge to Britain's decision to leave the European Union, or Brexit.
A group of politicians in Northern Ireland had brought a hearing before the Belfast High Court, arguing that lawmakers in the Stormont Assembly should have a say on whether to trigger negotiations with Europe.
Lawyers for the Britain's government had argued there was no legal barrier to Brexit.
The case is separate from a landmark legal challenge being heard before London's High Court, which argues that Parliament needs to act before Prime Minister Theresa May can trigger negotiations to leave the 28-nation bloc.
Stephen Booth of Open Europe, a pan-European think tank that promotes closer relationships between the UK and the EU, said the ruling will have little bearing on other legal challenges in Scotland or at Westminster.
