Oregon recently passed a Clean Fuels law, though it has not yet gone into effect. In order to make sure that it doesn't, a group of truckers and others in the fuel manufacturing industry has started a lawsuit to block the new regulations. These companies and individuals are not from Oregon, but from out of state.
According to the group, the new law is a violation of U.S. Constitution, breaking the commerce clause. They say that the companies that make biofuels in Oregon will get an advantage in the state that is unfair to others in the industry. Groups involved in the lawsuit include the American Fuel & Petrochemical Manufacturers, the Consumer Trade Association and the American Trucking Association Inc.
