 In a couple of respects, first of all this is not a treaty of all 27 member states of the European Union. This is a treaty which has been agreed by 25 of the 27. The second way that it is different is its ratification. This treaty will not require the unanimous agreement of all of the member states. In order for this treaty to come into effect, all that is required is that 12 members of the Eurozone countries ratified the treaty and it will then come into effect when the 12th country has ratified it or on the 1st of January 2013.
