[A]rcane rules and jurisdictional statutes often determine the course of global commerce, the terms of employment for millions of workers, and the very nature of justice for many in corporate America. The 2012-13 high court session, which concluded June 26, saw the [US Supreme Court] justices continue a multiyear pattern of interpreting regulations and statutes in a manner that insulates corporations from liability risks.

Evident in the court’s decisions is a deep-seated hostility to ambitious lawsuits aggregating the claims of hundreds or thousands of plaintiffs.
