U.S. Sen. David Vitter (R-La.), top Republican on the Environment and Public Works Committee, made the following statement regarding today's Supreme Court decision on whether the U.S. Environmental Protection Agency (EPA) went beyond their scope of authority as mandated by the Clean Air Act (CAA).

"This ruling clearly limits EPA's authority in some respects, but it's equally clear to me that the courts are still providing the Agency too much deference," said Vitter. "I'm not alone with concerns that the Agency is violating internal guidelines, including the Information Quality Act. And I hope - sooner than later - the courts will actually decide that the Agency cannot just make up numbers and science and violate these internal controls that should be taken seriously, like requiring emission reductions and the use of technologies that are based on shaky science and legal justifications."
