The prime minister's move dominated the newspapers Thursday, with The Times saying Johnson had "pushed Britain to the brink of a constitutional crisis".
He said if they don't have the "courage or the gumption" to follow through with the options, then Britain will leave the European Union at the end of October.
Absent a delay, Britain will leave the European Union on October 31.
Mr Johnson announced the surprise decision Wednesday to dismiss parliament - known as proroguing - next month for almost five weeks, claiming his new government needed to start afresh in order to pursue a "bold and ambitious" post-Brexit domestic agenda.
Gina Miller, a businesswoman and leading anti-Brexit campaigner, said she had applied for an urgent judicial review challenging "the effect and the intention" of the suspension.
The move, which had to be approved by Queen Elizabeth, limits the time opponents have to derail a disorderly Brexit, but also increases the chance that Johnson could face a vote of no-confidence in his government, and possibly an election. The latest tally was 470,000, and it was rocketing skyward, although any such debate would not lead to legislative action. The five-week break is the longest since 1945.
Meanwhile, there is a majority of British parliamentarians who refuse to accept a no deal Brexit, and plans were in the works to use Parliament's return from summer recess next week to prevent that exact scenario from happening.

Hancock said a suspension of Parliament would be going against what the men on the beaches of Normandy fought for during World War II.
The Financial Times predicted further political problems for the moves against Johnson, because a vote of no confidence "would need about eight Tory MPs to think the virtually unthinkable and vote down their own government, with the potential outcome of a quasi-Marxist Labour government led by Jeremy Corbyn". Wednesday's maneuver, if successful, would drastically narrow their window to next week.
New Brexit talks will take place twice a week to avoid a no-deal "nightmare", as the British government takes flak over its parliament shutdown.
As several protests were announced when parliament resumes on September 3, Corbyn said: "We will be back in parliament on Tuesday to challenge Boris Johnson on what I think is a smash-and-grab raid against our democracy".
In a blow for Johnson, popular Scottish Conservative leader Ruth Davidson stepped down after eight years during which she has revived her party's fortunes. Two years earlier, they had consented to staying in the United Kingdom in a referendum of their own. It is different from the dissolution of Parliament, which is done before a general election. The move brings to a close all parliamentary business that is being worked on - such as bills and motions - though some can be carried on to the next session.
The suspension would add to an already planned suspension - from mid-September for about three weeks - that is meant to allow the main political parties to hold their annual conferences. "One doesn't wish to make too many parallels with what is happening in the 17th century and yesterday, but sometimes it's just too tempting". Johnson and his team see that as weakening whatever leverage they believe they have with the European Union and, rather than let this scuttle their game of chicken with Brussels, have moved to suspend parliament shortly after it comes back into session early next week.
The official petition was posted on the UK Government and Parliament Petitions page shortly after Wednesday morning's announcement of the prorogation - which will reduce the time available to Members of Parliament to prevent a no-deal Brexit on October 31.
The action by Johnson, who became prime minister last month, prompted ruptures across the political spectrum, including among members of his Conservative Party.
Outside the House of Commons, lawmakers giving interviews had to speak over chants of "Stop the coup!" Realistically speaking, though, there's really nothing that can be done to stop it now that Johnson has received Royal Assent for the move, something that was never in doubt since it is customary for the Monarch to grant such requests from the government regardless of her own views on the subject.
