Is the Clean Air Act so badly flawed that it will cripple environmental enforcement and economic development alike unless the EPA and its state counterparts defy clear statutory provisions or, alternatively, spend $21 billion annually to employ an additional 320,000 bureaucrats?

That is a central issue in a recent lawsuit by Southeastern Legal Foundation (SLF), the Competitive Enterprise Institute (CEI), a host of lawmakers and several companies, who are petitioning the Supreme Court to review an appellate court decision upholding the EPA’s global warming regulations.

I discuss some of the legal issues today in a column on Forbes.com. My conclusion: The Court’s reading of the Clean Air Act in Massachusetts v. EPA (2007) and the EPA’s reading of the Act in regulating greenhouse gas emissions from “major” stationary sources cannot both be right — and both may be wrong!

Unless the Court is prepared to take ownership of the bizarre notion that the the Clean Air Act was wired from the start to self-destruct four decades later, it should either overturn the EPA’s regulation of stationary sources, revise its decision in Mass. v. EPA, or both.
