Facts of the Case

In order to protect its fisheries from parasites and non-native species, the state of Maine prohibited the importation of live baitfish. Robert J. Taylor, the owner of a bait business, violated the law and was prosecuted by Maine authorities.

Question

Did the Maine law unconstitutionally burden interstate commerce, violating the Commerce Clause?

Conclusion

No. In an 8-to-1 decision, the Court held that the limitation imposed by the Commerce Clause on state regulatory power was not absolute and that the States "retain[ed] authority under their general police powers to regulate matters of 'legitimate local concern.'" The Court found that Maine's ban on the importation oflive baitfish served a legitimate local purpose that could not adequately be served by available nondiscriminatory alternatives. The Court argued that the ban was not a simple case of "arbitrary discrimination against interstate commerce."
