The UK Supreme Court is now hearing arguments on Prime Minister Boris Johnson's controversial decision to suspend parliament ahead of Britain's exit from the European Union. Opponents say Johnson's motive was to prevent scrutiny and challenges from lawmakers, many who no longer support his plans to leave the European Union without a deal by the October 31 deadline. A lawyer for the UK government told the Supreme Court that if the judges find the prime minister's suspension of parliament unlawful, Johnson must take steps to remedy the situation. The hearings will run until Thursday with a verdict not expected until Friday at the earliest.
