Iris Irons operates a bait shop near the border and attempts to import live minnows from a neighboring state. State officials seize the shipment under a new statute that bars all out-of-state baitfish to protect local fish populations from parasites. Iris sues, claiming the ban burdens interstate commerce. The court upholds the statute because the measure advances a legitimate ecological interest and no nondiscriminatory alternative exists.
Island Manufacturing ships hazardous waste generated in its out-of-state plant to a disposal site in State B. State B charges Island a surcharge twice as high as the fee imposed on in-state generators. Island challenges the differential.

A facially discriminatory state law survives if it serves a legitimate and important non-economic local interest such as protecting ecological resources and no reasonable nondiscriminatory alternatives exist.
