Why Prorogation is So Important for Boris
Here is my take on the current situation....
The Hilary Benn bill forces the Prime Minister to bring back a Brexit Deal from Brussels for a meaningful vote on 19th October. If not, the PM must go to Brussels and ask for an extension to end January 2020. If an extension to end January 2020 cannot be granted by the PM then he must accept whatever extension that the EU give him.
So far, Mays Withdrawal Treaty has been voted on in the commons 3 times and been voted down repeatedly, on one occasion by the biggest majority in Parliamentary history and the last time it cost her, her job. Over the recent months, its clear that the EU will not change the Bill and only offered minor changes to the political declaration which is not legally binding (I refer to Geoffrey Cox Speech earlier this year when May brought back the political declaration for debate at the 2nd reading).
Under the current rules of Parliament, a bill cannot be presented to Parliament in the same Parliamentary session more than 3 times, unless the bill has been "significantly changed". As the WA will not be changed by the EU (they have repeatedly said so), this means that the bill cannot be brought back to Parliament for a debate and meaningful vote for the 4th time. In the current parliamentary session, this means Boris has only one option which is to ask for the extension in accordance with the Benn Bill as he cannot satisdy the requirement of bringing back Mays bill for the debate on the 19th.
Unless, of course there is a new Parliamentary session, in which case he can bring back Mays Withdrawal Act for the first vote in the new Parliamentary session.
However, there is one problem he has and that in order to end the current session and start a new one, he needs to prorogue Parliament and have a Queens Speech. Now we know what all the fuss was about with Gina Miller, the Supreme Court, the hysterical remainers and our ex-Prime Minister and chaotic remainer, John (hypocrite) Major. By having the Supreme Court (of EU fanatics) overrule the proroguing of Parliament by ruling that it was unlawful, it means that the existing parliamentary session has not ended and Mays withdrawal bill cannot be brought back on the 19th, forcing Boris to go for the extension by default (he can't get a new significantly changed bill from the EU).
So now, what Boris needs to do, is use the law that has been passed by the Supreme Court to prorogue parliament again for a minimum period and with a justifiable meaning. If he does this, there is nothing anyone can do about it. In the new Parliamentary session, he then needs to re-present Mays deal which will get voted down again (Conservative Whip, SNP, Greens, Liberals, principled Labour remainers) and then he is in a no-deal Brexit position again as he will have satisfied the requirements of the Benn Bill by bringing a "deal" back to Parliament by the 19th October.
So, expect another proroguing of Parliament in the next few days or so.....
That's how I see it now and why Boris is adamant he will not need to ask for an extension while not breaking the law.
I think he could be right ...
P.S. Here is the irony.
Boris has repeatedly chastised labour for their position of going to Brussels, getting a deal and then voting against it. If I'm right, the Tories will be doing just that
oh the irony !
