Ninth Circuit Rules Sailors Will Get Their Day in U.S. Court
RALEIGH, N.C.--(BUSINESS WIRE)--Today, the United States Ninth Circuit Court of Appeals ruled in favor of the U.S. sailors who were exposed to dangerous levels of radiation assisting in humanitarian relief efforts to Japan following an earthquake and tsunami in 2011. Based on the ruling, the sailors are able to continue their suit against Tokyo Electric Power Co. Holdings Inc. (TEPCO) allowing the sailors to pursue their case in the District Court in San Diego. It is possible that the nuclear meltdown at the Fukushima plant affected up to 75,000 U.S. citizens, even after TEPCO deemed the conditions safe.
