5. It would create a Cabinet Government of the new Union:  The Treaty would turn the European Council, the quarterly "summit" meetings of Member State Heads of State or Government, into an institution of the new Union, so that its acts and failures to act would, like all other Union institutions,  be subject to legal review by the EU Court of Justice. 

Legally speaking these summit meetings of the European Council would no longer be "intergovernmental" gatherings of Prime Ministers and Presidents outside supranational European structures. As part of the new  EU´s institutional framework, they would instead be constitutionally required to "promote the Union's values, advance its objectives, serve its interests"  and "ensure the consistency, effectiveness and continuity of its policies and actions." (Art. 9 amended TEU).  They would also "define the general political direction and priorities thereof"(Art.9b).

The European Council would thus become in effect the Cabinet Government of the new Federal EU, and its individual members would be primarily obliged  to represent the Union to their Member States rather than their Member States to the Union.  

The Lisbon Treaty would also give the EU a political President, a Foreign Minister - to be called a High Representative - a diplomatic corps and a Public Prosecutor.  The new EU would accede to the European Convention on Human Rights, as Ireland and all other European States have already done, including those outside the EU.

The Treaty would also set out the principle of the primacy of the laws of the new Union over the laws of its Member States(Declaration 27). The new EU would make the majority of laws for its Member States each year and under the Lisbon Treaty the new Union, which would replace the European Community, would get further power to make laws or take decisions by qualified majority vote in relation to some 68 new policy areas or matters where Member States currently have a veto.
