1. Traditional Definition:
“Federalism is a system of government in which power is constitutionally divided between a central authority and constituent political units (like states or provinces). The two levels of government are interdependent, and share sovereignty.”—Wikipedia
2. Iraqi Definition:
“Article 13: 1st - This constitution shall be considered as the supreme and highest law in Iraq. It shall be binding throughout the whole country without exceptions.
2nd - No law that contradicts this constitution shall be passed; any passage in the regional constitutions and any other legal passages that contradict this constitution shall be considered null.”
Remember: our Constitution was written to limit the federal government, not the state governments. That's why the States have their own constitutions! Compare the Tenth Amendment.
Given the lack of Iraqi legal history, the supremacy of Islam imbedded in the document and the hasty drafting of this constitution, it is not certain how this article will be used.
