From the LA Times:
The Supreme Court justices appeared closely split Wednesday on whether environmental laws can be used to protect whales and other marine mammals from the Navy's use of sonar off the coast of Southern California. A Bush administration lawyer argued that when national security is at stake, the president and his top military commanders are entrusted with setting the rules.
The government is urging the high court to throw out a Los Angeles judge's order that put limits on the Navy's operations. Acting on a suit brought by the Natural Resources Defense Council in Santa Monica, U.S. District Judge Florence-Marie Cooper ordered the Navy to shut down its high-intensity sonar whenever a whale or marine mammal is spotted within 1.25 miles of the ship.
