This work applies the constitutional analysis method on the evaluation of the EU constitutional setting's change after the possible approval of the Lisbon Treaty. We will focus on the part of the Treaty that has an impact on the character of the legislation connected with commodity taxation. Specifically, we will analyze the change of the voting rules of the Council and the change of the constitutional cognizance of the Council. After we draw the parallel between the Council and the revenue-maximizing Leviathan, we will be able to advocate for the conclusion of our analysis which is that the base and rates of the commodity taxation will change to the disadvantage of the taxpayer after the approval of the Treaty
