Appeals Court OKs Navy Use of Sonar

A federal appeals court on Friday said the U.S. Navy could use high-power sonar during exercises off the Southern California coast despite the technology's threat to whales and other marine mammals. A majority on a three-judge panel of the 9th Circuit U.S. Court of Appeals said the Navy can use the high-power sonar in 11 planned training exercises in its reversal of a lower-court order banning the practice.
