This Bill started its passage through Parliament on 2 April 2019 and looks to remove a bargaining chip from the UK in it’s discussions with the EU to prevent No Deal. The Bill completed its passage through Parliament (House of Commons and House of Lords) on 08 April 2019.
In trying to understand the consequences of this legislation it is useful to explore a Research Briefing prepared for the House of Commons:
By the automatic operation of EU law, the UK leaves the EU on 12 April 2019 regardless of whether a deal has been ratified. The purpose of the Bill is to reduce the risk of the UK leaving the EU without a deal, or at least to delay that outcome beyond 12 April 2019 if that is what MPs want and the European Council is prepared to agree to it.
An important point here is that any extension needs to be agreed by the EU Council! They can reject a selected extension and/or propose their own date.
The day after the day on which this Bill gets Royal Assent, the Prime Minister would have to table a motion. This motion must seek Commons approval for a proposal that the UK asks the European Council for an extension to Article 50. The motion must set out the Prime Minister’s preferred extension date.
Following Royal Assent of the Bill on 08 April 2019 (when it became Law) the following Motion has been tabled for debate on 9 April 2019
The Prime Minister
That this House agrees for the purposes of section 1 of the European Union (Withdrawal) Act 2019 to the Prime Minister seeking an extension of the period specified in Article 50(3) of the Treaty on European Union to a period ending on 30 June 2019.
As it happens the PM has already written to Donald Tusk (on 5 April 2019) requesting an extension to 30 June 2019 with an option to terminate early. Has the fast tracking of this Bill through Parliament been a complete waste of time ?
If the EU offers a different extension to the one proposed, the PM the must seek approval from the House of Commons before the revised date can be agreed with the EU.
The Act also provides a further role for the Commons in the event that the European Council does not agree to the Prime Minister’s request but proposes an alternative date. In those circumstances, the Prime Minister would have to seek further Commons approval before agreeing to that revised date and thereby giving effect to it in EU law.
