U.S. Chamber argues plaintiffs must prove causation rather than simply proving “any exposure” to asbestos

March 28, 2013

NCLC urged the Ninth Circuit to rule that asbestos plaintiffs must prove causation to make out a claim, rather than simply proving “any exposure” to asbestos. This case involves a worker who contracted mesothelioma from asbestos exposures during his employment in a refinery, and separately in a paper mill. The plaintiffs argue that “any exposure” to asbestos should be deemed causative of mesothelioma. The “any exposure” theory stands in sharp contrast to normal causation methodology, which requires an expert to assess a dose first and then demonstrate that the dose received was sufficient to cause disease. NCLC argued that the “any exposure” theory is the engine driving the current attempt to bring increasingly trivial exposures into asbestos litigation. If the theory survives a Daubert inquiry, the case will likely go to the jury, regardless of the limited exposure.

NCLC amicus brief filed 5/26/11. Petition for rehearing en banc granted 3/25/13.

NCLC en banc amicus brief filed 3/28/13. Decided 1/15/14.
