Brief Fact Summary. Iowa prohibits the use of 65 foot doubles (a certain type of truck) within its borders, but makes certain exceptions for the same trucks used for the benefit of Iowa residents.
Synopsis of Rule of Law. State regulations designed to promote public health or safety, but further such purposes only marginally and interfere with commerce substantially may be invalid under the Commerce Clause.
Issue. Was Iowa’s statute scheme an unreasonable safety measure enacted pursuant to its police powers?
Held. Yes. The judgment of the Court of Appeals is affirmed.
Iowa failed to produce any persuasive evidence that 65-foot doubles are less safe than 55-foort singles. Plus, Iowa’s law substantially burdens interstate commerce insofar as it uses regulations out of step with all of its neighboring State’s regulations. Moreover, Iowa discriminates against out-of-state interests by providing Iowan’s exemptions that are not extended to out-of-state interests.
Although the Supreme Court of the United States usually (Supreme Court) defers to the judgment of the State legislatures as to the justification of its laws concerning local concerns, less deference is due them in cases such as these: where the State’s safety justifications appear illusory; and where local regulation places a disproportionate burden of its statutory scheme on out-of-state interests.
Concurrence. Justice William Brennan (J. Brennan) states that even if the burdens and benefits are related to safety, protectionist legislation is unconstitutional under the Commerce Clause.
Less deference to the legislative judgment is due, however, where the local regulation bears disproportionately on out-of-state residents and businesses.View Full Point of Law
