Excerpt from Popular Government, Vol. 74: Spring/Summer, 2009 What is constitutional preemption? The u.s. Supreme Court has consistently ruled that the federal government has broad and exclusive power to regulate immigration.6 A state or local law will be constitutionally preempted if it at tempts to regulate immigration. Under this test, the relevant question is Does the state or local law regulate immigration - does it make a determin ation of who should or should not be admitted into the country and the conditions under which a legal entrant may remain - or does it simply pertain to immigrants. State and local laws that attempt to regulate immigration violate the Supremacy Clause of the u.s. Constitution and are therefore preempted by federal law, even in the absence of federal legislation.
