A federal lawsuit aimed at blocking the implementation of Oregon’s controversial low-carbon fuel standard has been dismissed.

The lawsuit, filed by three national industry groups representing oil and trucking companies, claimed that the fuel standard, known as the “clean fuels” program, violated the U.S. Constitution’s commerce clause by discriminating against out-of-state fuel and biofuel companies. It also claimed the program is pre-empted by the federal Clean Air Act.

U.S. District Judge Ann Aiken in Eugene dismissed all those arguments in a decision released Thursday.
