High Court told case could be struck out on consent from both sides
The case was taken by a British barrister, Jolyon Maugham QC, along with Northern Ireland Green Party leader and MLA, Steven Agnew, Jonathan Bartley, co-leader of the Green Party of England and Wales, and Green Party MEP for the south-east of England, Keith Taylor.
The proceedings were aimed at establishing if Britain can halt Brexit after triggering Article 50 of the Lisbon Treaty.
The plaintiffs wanted the High Court to refer issues in the case for determination by the Court of Justice of the EU (CJEU).
They sought various declarations or interpretations of the Treaties of the EU, including a declaration that Article 50, once triggered, can be unilaterally revoked by the UK government.
Lawyers for the State and the Attorney General had asked that the issue of jurisdiction be decided first.
Among the issues raised by the State was whether or not the Irish High Court had any power to grant declarations sought by the plaintiffs and why the case was brought here.
