Supreme Court Judgement on the Prorogation of Parliament

The Supreme Court unanimously ruled the prorogation unlawful and void holding it was done to frustrate or prevent the ability of parliament to carry out its functions without reasonable justification. The court held prorogation was not a proceeding in parliament under the Bill of Rights and stated the court certainly could declare therefore that the advice was unlawful. The judgement said the court was 'bound to conclude' there was no reasonable justification.
