Boris Johnson verdict
Boris Johnson acted illegally when he shut down British parliament for five weeks.
That's the verdict that was delivered this morning after a panel of eleven justices voted unanimously.
Lady Hale called Johnson's decision to suspend parliament, "unlawful, void and of no effect."
She also commented on the "extreme" effect shutting Commons has had on democracy.
Lady Hale demanded that, "immediate steps to enable each house to meet as soon as possible," are made.
What happened?
UK prime minister Boris Johnson advised the Queen to suspend parliament until 14th October.
Following this morning's ruling, this advice could be considered misleading.
Johnson made the decision to prevent MPs from discussing Brexit.
He wants to Britain to leave on 31st October with or without a deal.
The prime minister feared that if parliament met in the meantime a law could be passed that would delay or even cancel Brexit.
Resignations
Boris Johnson has previously said he would not step down if his decision was ruled unlawful.
However, following this morning's verdict a number of politicians are calling for him to resign.
MP Ian Blackford said Johnson, "must resign immediately".
Labour leader Jeremy Corbyn is also calling for a resignation.
Speaking to his party in Brighton this morning he said, "I will be in touch immediately to demand that Parliament is recalled so we can question that Prime Minister."
While he spoke, Labour members chanted "Johnson out! Johnson out!"
Elsewhere, Brexit Party leader Nigel Farage called for the Prime Minister's chief adviser Dominic Cummings to be removed from his role.
Boris Johnson has yet to respond to the verdict.
British parliament has been suspended since 9th September.
