[JURIST] A group of class-action suits against cell phone manufacturers has been revived after the US Fourth Circuit Court of Appeals [official website] reinstated the cases Wednesday. The five suits claim the cell phone industry has failed to adequately protect users from radiation emitted by the phones and seeks to require the provision of headsets with phones, as well as punitive damages. The court ruled that because the claims only raised issues relating to state claims, including consumer protection, they were not preempted by federal laws regulating cell phones. Originally filed in several state courts, the suits were consolidated in federal court, but District Judge Catherine Blake dismissed them in light of federal limits on radiation emissions by cell phones.
