A New York appeals court has ruled that the mother of a woman who was severely injured at a music festival and later died can discover ticket sales records and compel the defendants, who are represented by the same legal counsel, to address conflicts of interest.

An Appellate Division, Third Department, panel decided that the festival, known as Camp Bisco, and other named defendants—including promoters, owners of up-state grounds where the festival was held, and those in charge of coordinating festival medical transportation—must hand over sales records because they are “clearly material and relevant to plaintiff’s claim.”
