On June 2, 2010, the U.S. Court of Appeals for the Ninth Circuit held that a non-settling PRP's right to contribution under CERCLA was a legally sufficient interest to justify intervention to challenge a proposed consent decree between the federal government and the settling PRPs, joining ranks with the Eighth and Tenth Circuits, the only other U.S. appellate courts to address the issue. The case is U.S. v. Aerojet Gen. Corp., No. 08-55996 (9th Cir. Jun. 2, 2010).
