More Anti CAP

The story of the anti CAP issue has a twist in the tale.

A petition calling on the European Commission to transfer the money will be handed out in hundreds of churches across Britain at the end of services over the festive period with the aim of collecting a million signatures. This would activate the implementation of a clause in the new European Union draft constitutional treaty. The commission is bound to act on any petition that has more than a million signatures of people from across Europe.

Forgive my ignorance, but when exactly did the constitution come into force?
