WASHINGTON, D.C. — The U.S. Supreme Court upheld Michigan’s truck fees in two cases June 20, dashing the American Trucking Associations’ (ATA) hopes that the fees would be seen as a violation of the federal Commerce Clause and a barrier to interstate commerce. According to ATA’s vice president of law, Robert Diggs Jr., Michigan charges truckers from outside Michigan a $100-per-truck fee for doing business inside Michigan, which he said earlier this year is in direct violation of the federal Commerce Clause. Back in February, when the high court agreed to review the cases, ATA President and CEO Bill Graves had argued that the fees were “discriminatory” and that they “impede the free flow of commerce.” A second case had to do with the annual $100-per-truck decal fee Michigan assesses on Michigan-plated interstate carriers. The ATA said that the fees are in violation of the $10 maximum set by the Single State Registration System (SSRS), a federal program by which states register interstate motor carrier operations. The Court disagreed with the legal challenges in both cases.
