This third edition of Mass Tort Litigation is revised to reflect developments in mass tort litigation in the decade since the second edition. The revised text addresses mass tort class litigation in a post-Amchem/Ortiz world. New materials have been added concerning expanded use of MDL auspices, bellwether trials, non-class aggregate settlements, the quasi-class action, the aggregate settlement rule, and the ethical duties of attorneys with clients in MDL and non-class proceedings. Two revised chapters focus on challenging issues in mass tort litigation: damage sampling; statistical proof; limited issues classes; multiphase trial plans; sub-classing; and res judicata. New cases have been added that reflect resolution of various pharmaceutical mass torts (Vioxx and Zyprexa); personal injury mass torts (the NFL and Collegiate Athletes concussion litigation); products liability mass torts (the Ford and GMC Ignition Switch litigations; heart-valve cases; tobacco litigation; the moldy washer cases); natural and man-made environmental disasters (the Hurricane Katrina and BP Gulf Oil Spill litigation); and the World Trade Center events. A new chapter includes materials on the Class Action Fairness Act of 2005, including the concept of the “mass action.” Finally, the third edition includes materials on so-called “fund approaches” to resolving mass tort litigation.
