It's possible with complex legislation to read what you think it says, rather than what it actually does say. This erroneous approach underpins an invalid argument that Article 2.79 of the Lisbon Treaty will result in corporation tax harmonisation.
Proponents of a No vote argue that Article 2.79 of the Lisbon Treaty would insert a six word amendment 'and to avoid distortion of competition' to a renumbered Article 113.
