The senators of Delmarva would like to enact a statute banning the importation of any plant material into the state. Although the ban may be burdensome on interstate commerce, the state’s first concern is protecting their income-producing agricultural byproducts from micro-organisms that may affect the health of the crops. There is no effective way to inspect plant material for micro-organisms at its border. Is this statute legally legitimate? What clause of the Constitution would you use to perform your analysis and what are the elements of the test that would be applied to test its constitutionality?
