I am generally loath to speculate about what the Supreme Court will do based on oral argument, but the overwhelming reaction to the oral argument in Sackett v. EPA was that EPA is going to lose. What would a loss mean? In simplest terms, EPA would no longer be able to issue enforcement orders under the Clean Water Act without those orders being subject to judicial review. Such a decision would undeniably be significant. Everyone practicing in this area knows how coercive EPA enforcement orders can be. A person who thinks that he is not liable or that the order is inappropriate, and faced with having to violate the order and wait for EPA to bring an enforcement action to obtain judicial review, is truly between a rock and a hard place – or perhaps Scylla and Charybdis (I’m not sure which, but it’s not good, either way). The opportunity for preenforcement review would eliminate much of EPA’s coercive power.

The big question is whether a decision against EPA would be so broad as to make it clear that EPA’s order authority under other statutes, such as CERCLA, would be similarly affected. Here, speculation really is difficult, because the Supreme Court could invalidate EPA’s CWA authority several different ways, with differing impacts on other statutes. Readers who want to explore the issue in more depth than a blog post can review an article I did in the ABA Superfund and Natural Resource Damages Litigation Committee Newsletter.
