For the newfound constitutional geeks, introducing the Padfield Principle:

Unsurprisingly, given what's happened tonight, many of govt's opponents are furious about his approach to sending letter to Tusk, with his own extra correspondence - as it happens, Lord Pannick who beat the govt in Supreme Court case talked about possibilities earlier...
Fascinating to read what he said, here's 1st chunk - 'The Benn Act..does not, and could not, oblige the EU Council to grant an extension,nor does it prevent the PM reminding the EU member states that he does not want an extension, wants to leave on 31 October'....
He goes on..'and is sending the letter only because Parliament has required him to do so. I do not see that the Benn Act can sensibly be interpreted as requiring the Prime Minister to abandon his policy objectives.'
But Pannick says.. 'There is a very fine line between not frustrating the Benn Act and the PM making clear to other EU leaders that his policy is unchanged. What if the PM telephones another EU leader on Monday and encourages him or her to oppose or even veto an extension?'
And here, in Pannick's words, is the preview for what may happen next week - the peer and QC said, 'That would be an interesting Supreme Court case.' .. stage is set

A thread on Johnson's request for an extension under the Benn Act 1.
Number 10 had a problem when the Letwin Amendment passed
Under the Benn Act there was an inescapable duty for an extension request to be sent
No way round it 2.
Had the request not been sent, the Benn Act would have been breached
The averments (ie, promises) to the Scottish court would have been breached
The Lord Chancellor, Scottish Advocate General, Attorney General all would (or should) resign 3.
A government breaching the law - or even just breaching the averments - would also be creating an immense moral hazard in all other legal cases
No court would ever give the government the benefit of the doubt when considering potential court orders again
Huge problem 4
So a letter would have been sent
The advice from government lawyers would have been unequivocal
The question then came how to dress it up 5.
Send a side letter?
But the problem here was our old friend Padfield
What could the government do about Padfield? 6
Padfield is the constitutional principle that a government minister cannot do a thing (or not do a thing) that would frustrate a statute - in this case the Benn Act
The principle based on a leading 1968 case
Constitutional law 101 7.
So any side letter had to avoid frustrating the purpose of the Benn Act letter
The Benn Act letter had to be a valid extension request
A side letter could not say :the other letter is not a Benn Act request", disregard the Benn Act letter or similar 8.
And so the side letter would have been lawyered to the hilt
And it must have been personally signed off by the Attorney General and the Advocate General - because of the averments to the Scottish Court, they both had a professional obligation to ensure no breach of averments 9.
And the side letter is (in my view) Padfield-compliant
The Benn Act letter retains its full legal force, and is a valid request for an extension, and there is nothing in the side letter which frustrates this
Side letter just legally inconsequential waffle 10.
And the proof of Padfield-compliance is in the pudding
Tusk and the EU27 immediately accepted the Benn Act letter as valid
The other letter disregarded like Xmas wrapping paper
Statutory purpose of the Benn Act letter fulfilled 11.
Had Tusk/EU27 came back and said "legal position unclear, please clarify" or "one letter contradicts the other" then there would have ben a Padfield problem
But they didn't
No hesitation for a moment 12.
And the Number 10 had a further clever wheeze to distract the easily distracted
Let's say the Benn Letter was unsigned!
Utter red herring
No requirement whatsoever that it be signed
Letter was sent as set out in schedule to Benn Act
Full compliance with the Act 13.
The "Number 10 source" then briefed that the government would see opponents in court, seeking court drama
Perhaps the Scottish Court on Monday will take matter further - I don't know
But it shouldn't, IMO
The Benn Act request has been sent and is accepted as valid 14.
There is no need for court drama, still less this being "played out in the Supreme Court"
The government lawyers made sure that the side letter would not have, and did not have, any frustrating effect tot he Benn Act letter, and so it did not 15.
I may be wrong - it may be that the Scottish courts, and Supreme Court - do wade in, and make a point of condemning side letter
I will eat my tweets in a brown bread sandwich
But - if the side letter was to get EU to reject the Benn Act letter as a valid request, it failed 16.
If you remember the Article 50 notification, there were paragraphs of policy waffle - but it was the two or three operative sentences that mattered
The waffle was disregarded
Same again here 17.
The brute legal fact is that there is a valid extension request in place
One which the government said it would not send
Once capable at law of leading to an extension 18.
And after all "Number Ten Source" briefings and bluster, and clever-seeming amateur hour wheezes to evade Benn Act breathlessly repeated by uncritical media
After all that noise
All they had in the end was: "let's not sign the letter!"
Pathetic, really
Classic Dom
