On April 23, 2014, the Supreme Court heard oral argument in CTS Corp. v. Waldburger. The question in this case is whether the U.S. Court of Appeals for the Fourth Circuit correctly interpreted the preemption provision of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) to apply to state statutes of repose--which typically impose a final time limit for bringing suit a certain amount of time after the defendant took action--in addition to state statutes of limitations, which simply impose time limits based on when a particular cause of action accrues. -- To discuss the case, we have Allyson Ho, who is a partner at Morgan Lewis.
