The United Kingdom’s Supreme Court unanimously ruled that Prime Minister Boris Johnson acted unlawfully when he decided to suspend parliament. The BBC reports:

Mr Johnson suspended – or prorogued – Parliament for five weeks earlier this month, but the court said it was wrong to stop MPs carrying out duties in the run-up to Brexit on 31 October.

Commons Speaker John Bercow confirmed MPs would now return on Wednesday.

This all unfolded with Johnson in New York City for the United Nations General Assembly.

While the decision certainly seemed tied to Brexit, CBS reminds us:

Johnson was accused of suspending, or “proroguing” the legislature to limit the time lawmakers have to debate and intervene in his Brexit policy. He had insisted the prorogation was standard operating procedure for a new prime minister, and that it had nothing to do with the looming Brexit deadline.

Now there are calls for Johnson to leave office.

"I invite Boris Johnson… to consider his position and become the shortest serving Prime Minister there's ever been."

No word on whether Johnson will return to England immediately this morning.
