Section 107(a) of the federal Superfund statute begins "[n]otwithstanding any other provision or rule of law, and subject only to the defenses set forth in subsection (b) of this section –" certain "covered persons" are liable for certain response costs and natural resources damages. 42 U.S.C. § 9607(a)(emphasis added). The problem is that section 107(b) does not seem to be complete. It lists defenses of "act of God," "act of war," or "act of a third-party." The statute contains other defenses, and the courts have recognized more. What then should be made of that opening phrase? I explore this issue in my June column for the Legal Intelligencer / Pennsylvania Law Weekly. Read Defenses to Superfund Claims: Is Section 107(b) the Complete List?, 35 Pa. L.
