The EU Withdrawal (No 2) Act, often referred to as the Benn act, is a law that was passed by MPs in an attempt to prevent Boris Johnson's government leaving the EU without a deal.
Scottish judges have delayed a final ruling on whether Boris Johnson is in contempt of court to ensure he agrees to an extension to Brexit.
British Prime Minister Boris Johnson will again try to put his Brexit deal to a vote in Parliament on Monday after he was forced by his opponents to send a letter seeking a delay from the European Union.
He told Deutschlandfunk radio that he wouldn't have a problem with an extension by "a few days or a few weeks" if that rules out a no-deal Brexit.
Act, known as the Benn act, also requires the prime minister to accept an extension if it is offered by Brussels and the 27 other European Union member states. The form of the letter that the prime minister must send is set out in full in the act. In a statement, he said a delay "would not be in any party's interest".

O'Neill read a transcript of undertakings by Andrew Webster QC, one of the United Kingdom government's lawyers, to the court on 9 October where Webster agreed that sending a second letter that tried to undermine the extension request "would be inconsistent" with Johnson's pledges in court to uphold the Benn act's provisions.
Johnson's first effort to get parliamentary backing for the deal he sealed against heavy odds last Thursday in Brussels was scuttled at a very rare Saturday sitting of British MPs.
Lawmakers pushed through an amendment obliging a furious Johnson to ask for an extension until the British legislation governing the withdrawal is drafted and passed.
Bercow says the vote sought by the government was "in substance the same" as one held on Saturday and it would be "repetitive and disorderly" to allow a new vote Monday.
"There is every opportunity for the government, with the support of the House, not only to have its say but to get its way by the end of October".
But Johnson could also fulfill the terms of the Benn act and avoid any further hearings of the legal challenge if he succeeds in getting a Brexit deal accepted and passed in the Commons and agreed by the European Union in time to leave on 31 October.More news: Two arrested over racism that forced FA Cup match abandonment
But the deck against Johnson seems stacked.
"Parliament needs a straight up-and-down vote on the deal - do MPs want to respect the referendum like they claim to. or do they want to frustrate and cancel Brexit altogether?" it added.
The main opposition Labour Party is trying to create a cross-party alliance that would back Johnson's deal on the condition that it is fixed to keep Britain in a customs union with the EU.
The DUP broke ranks and voted against Johnson's agreement Saturday because it created new trade regulations for goods moving between Northern Ireland and the rest of the UK.
"We are clear where we stand on the customs union, that's something that the can not support and will not support", Shannon said.
The Brexit-supporting DUP appeared open to the suggestion after rejecting another amendment backed by Labour that would put up any eventual deal for a confirmatory referendum.More news: Dabo Swinney promises consequences for Andrew Booth punch
