The federal judge in the MDL involving BPA in baby bottles refused last week to certify three proposed multistate classes in this multidistrict litigation. In re: Bisphenol-A Polycarbonate Plastic Products Liability Litigation, No. 08-1967 (W. D. Mo. July 7, 2011).

On August 13, 2008, the Judicial Panel on Multidistrict Litigation centralized the cases; there are approximately twenty four cases left in this litigation.

The court’s discussion focused on three of the components required for certification: commonality, predominance, and superiority. The court said it focused on these issues because they presented "the most insurmountable obstacles to" plaintiffs’ request.
