Ninth Circuit questions auto groups’ right to intervene in emissions waiver dispute

The Ninth Circuit is probing whether auto industry groups have the standing to join a lawsuit challenging California's authority to deny federal emissions standards waivers. These groups argue they're directly affected financially by the decision, but the court is skeptical about their claims. This case is significant as it could reshape the balance of power between state and federal environmental regulations, with implications for future policy decisions on emissions and climate change. The outcome might influence how states assert their environmental rights against federal mandates.
