Britain’s highest court ruled Tuesday that Prime Minister Boris Johnson violated the law when he asked Queen Elizabeth to suspend parliament. The Supreme Court said that Johnson’s request was “unlawful, null and of no effect.” All eleven justices agreed with the ruling. The court said that Johnson’s action prevented parliament from carrying out its duties of “holding the government to account.” The order for a five-week suspension of parliament came as Britain prepares to withdraw from the European Union by October 31. However, no deal for leaving the EU has been reached. Johnson has promised to cancel Britain’s EU membership with or without a trade agreement with European officials.
