The High Court has made a bad mistake – it has wrongly lent its authority to a claim that undermines both democratic self-government and the rule of law. The basic point of this litigation has not been to defend parliamentary democracy.  Rather, the aim has been to introduce a new stumbling block to Brexit by providing sympathetic MPs and peers with an opportunity to frustrate the referendum result. The Government is right to appeal and the Supreme Court should promptly overturn the High Court’s dubious decision.

See here for a summary of the court’s judgment; and here for the full judgment.
