Antitrust

The past decade has witnessed significant development in class action certification standards in the antitrust context, and the past year has been no exception. Questions of predominance continue to be at the forefront, although the numerosity requirement has also been put to the test. This chapter places these issues of class certification in context by tracing the standards of certification and discussing the evolution of the ‘rigorous analysis’ requirement now required by federal courts. It then spotlights notable decisions from the past year that have grappled with challenges to the sufficiency of plaintiffs’ statistical models used to demonstrate the preponderance of class-wide questions, principally on the issue of showing class-wide harm, and with the number of putative class members required to be sufficiently numerous for certification.
