Johnson implicitly warned lawmakers on Monday that he would seek an election if they tied his hands in talks to negotiate a last-minute divorce deal, ruling out ever countenancing a further delay to Brexit, originally due to take place last March but now scheduled for October 31.
"There is no consent in this House to leave the European Union without a deal", Labour leader Jeremy Corbyn countered.
Johnson's aides had also publicly denied a suspension was planned three days before it was finally announced.
Despite a warning that Johnson would seek an election if they tied his hands over Brexit, a bloc of opposition lawmakers and rebels in Johnson's party defied him with what they cast as an effort to stop an economically ruinous no-deal departure.
Ex-justice secretary David Gauke, who is among the senior Tories who have put their name to the cross-party legislation, said if MPs did not act then Britain would leave without a deal on October 31.
At a hearing on Tuesday, the lawyer representing more than 70 lawmakers told Scotland's Court of Session that two weeks before Johnson's announcement, he was sent a note from an aide asking if he wanted to prorogue, or suspend, parliament from mid-September.
'But I'm afraid that's not what the Prime Minister wants to do and that was made very clear by his statement outside Downing Street last night. But Johnson insists the potential for leaving without a deal must remain as a bargaining chip in negotiations with the EU.
Britain's pound plunged to its lowest level in two years after Prime Minister Boris Johnson threatened to call a general election in October.
Labour's Corbyn told parliament that Johnson's was a government with "no mandate, no morals and, as of today, no majority".
He said: "I don't want an election, you don't want an election".
On a day of high drama and acerbic debate in the House of Commons, lawmakers returned from their summer recess to confront Johnson over his insistence that the United Kingdom leave the European Union on October 31, even without a withdrawal agreement to cushion the economic blow. The judge could rule as soon as Wednesday.
A no-deal Brexit is considered unsafe because it will sever decades of seamless trade with the single market of 500 million, with many experts predicting a no-deal Brexit could tip the UK's economy into a recession.
Leaked government assessments have warned that no-deal could lead to food, fuel and medicine shortages, but ministers insist they can prepare for much of this.
Corbyn accused the federal government on "hiding from scrutiny, hiding from the people and trying to hide us from their true intentions" as he questioned Johnson's progress in negotiations.
"The one thing that has helped focus minds in the European Union is that we're leaving come what may and we've got a very focused task of what a good deal would look like", Foreign Secretary Dominic Raab told ITV.
"I believe we will get a deal at that crucial summit in October". "But the lingering doubt they've got is: Will the shenanigans in Parliament somehow lead to the cancellation or the delay of Brexit?"
