As the British Prime Minister went to give a speech to US and Canadian business leaders in New York, he refused to answer reporters' questions on the British Supreme Court ruling that said his suspension of Parliament was unlawful.
In a major blow to Boris Johnson, Britain's highest court ruled on Tuesday that his decision to suspend Parliament for five weeks in the crucial countdown to the country's Brexit deadline was illegal.
The unanimous, strongly worded Supreme Court judgment declared the order to suspend Parliament "void and of no effect."
The court found that Johnson acted to limit debate on Britain's impending departure from the European Union in violation of Parliament's constitutional role.
Back in London, Parliament will resume its deliberations Wednesday at 11:30 a.m. (10:30 GMT) - without Johnson, who is in New York for the United Nations General Assembly.
