Now the counter terrorism bill will in all probability be rejected by the House of Lords very firmly. After all, what should they be there for if not to defend Magna Carta.
But because the impetus behind this is essentially political - not security - the government will be tempted to use the Parliament Act to over-rule the Lords. It has no democratic mandate to do this since 42 days was not in its manifesto.
Its legal basis is uncertain to say the least. But purely for political reasons, this government's going to do that. And because the generic security arguments relied on will never go away - technology, development and complexity and so on, we'll next see 56 days, 70 days, 90 days.
But in truth, 42 days is just one - perhaps the most salient example - of the insidious, surreptitious and relentless erosion of fundamental British freedoms.
And we will have shortly, the most intrusive identity card system in the world.
A CCTV camera for every 14 citizens, a DNA database bigger than any dictatorship has, with 1000s of innocent children and a million innocent citizens on it.
We have witnessed an assault on jury trials - that bulwark against bad law and its arbitrary use by the state. Short cuts with our justice system that make our system neither firm not fair.
And the creation of a database state opening up our private lives to the prying eyes of official snoopers and exposing our personal data to careless civil servants and criminal hackers.
The state has security powers to clamp down on peaceful protest and so-called hate laws that stifle legitimate debate - while those who incite violence get off scot-free.
This cannot go on, it must be stopped. And for that reason, I feel that today it's incumbent on me to take a stand.
I will be resigning my membership of the House and I intend to force a by-election in Haltemprice and Howden.
