DislikedIf that were the case (and I'm not saying it isn't), that would be like having a rule that votes on snow plow funding can only be done with all congressman from Mississippi present.Ignored
I got a few minutes so I will bite.
We all use the term EFSF, even though technically it is wrong. The EFSF has been around for 2 years and is currently active, it is registered in Luxembourg and expires in 2013. The "EFSF" that most of us talk about here is actually the EFSM (European Financial Stabilisation Mechanism) that is going to replace the EFSF. It was Germany that considered it a change of treaty (the Lisbon one) so all members need to vote on it and ratify it unanimously.
The current EFSF can only supply money in conjunction with the ECB or IMF, the EFSM can operate independently.
I briefly touched a few weeks back on how the EU is changing its QMV system to vote so in future a consensus is no longer required to change treaties.
So really we are talking about the ESM or EFSM, not the EFSF.
The above is a very rough summary of what the EU takes a good few thousand pages of rubbish to describe.
