Massachusetts Supreme Court: Commonwealth of Mass. ex rel. Rosenberg v. JPMorgan Chase et al.

The brief explains that the Massachusetts False Claims Act is modeled after the federal False Claims Act with substantially identical public disclosure provisions, discusses the purpose and history of the public disclosure bar, explains the proper definition of “news media,” that the bar does not preclude outside relators from moving forward when they base their claims on data analysis and industry expertise, and that even if a disclosure had occurred, outside relators can qualify as original sources.
