Just to make one thing clear: Before the treaty comes into force it needs to be voted on by the Euroepan parliament and national parliaments. Before the votes the treaty will be published. What is a highly guarded secret are the current <i>drafts</i>, not the final agreement.<p>It&#x27;s actually not really different from how most laws are written, especially those proposed by the government. While those are in the drafting phase MPs usally don&#x27;t have access at all.
