Miller in the Supreme Court: a welcome reminder of the function of a constitution and the rule of law

The Supreme Court’s 8:3 ruling against the government is measured and restrained in tone – but it is the most important constitutional case the Court has ever heard, writes Jo Murkens. The Justices have ruled that the government cannot leave the EU without Parliament’s consent. And while they also declared EU membership a reserved matter and therefore one that must be decided at Westminster rather than by the Northern Ireland Assembly, this is unlikely to be the end of the story.
