But the appeals court said that has never before been a justification for a court to examine a proposed rule that could still be changed before it becomes a final regulation.“They want us to do something that they candidly acknowledge we have never done before,” wrote Judge Brett Kavanaugh. “We do not have authority to review proposed agency rules.”The court also said public statements by EPA officials about what the rule will do are not considered final agency action.The rule the EPA proposed last year is a centerpiece of Obama’s efforts to reduce pollution linked to global warming and one of his most significant acts during his final years in office. It would require states to cut carbon emissions by 30 percent by 2030. Each state has a customized target and is responsible for drawing up an effective plan to meet its goal.
