So, what the hell happened in the House of Commons last night?

Factual Questions
1

So something, not quite sure what, happened in the House of Commons last night wherein the government tried to trick the house out of a vote on the European Arrest Warrant. The speaker seemed pretty pissed off with what happened, and Tory backbenchers lined up to call their own government crooked, tyrannical and trying to slip past parliamentary executive oversight.

What actually happened? Is the European Arrest Warrant now legally in force in Britain or not? May seems to be implying that assent to 11 regulations implies assent to the 24 other regulations, including the EAW, that the house was barred from voting on. Is she right, or is the EAW likely to fall over at the first legal challenge in British courts? Further, how can the government call a vote on one matter and then change what it is the members are supposedly voting for under their feet?

To quote Baldrick:

“Well, no, it’s not a particularly cunning trick because we’ve seen through it… But obviously they thought it was cunning when they thought it up.”

The whole affair is summarised very well at EU Law Analysis: What just happened? The House of Commons ‘vote’ on the European Arrest Warrant.

This is the Telegraph’s take - that hyper-paranoid Tory backbenchers were incited by the Speaker criticising the Government, and the Opposition rubbing their hands and watching the sparks fly.
