WASHINGTON (AP) — The Supreme Court won't hear an appeal from a radical environmentalist group found in contempt of court for disrupting Japanese whale hunters off the waters of Antarctica.

The justices on Monday let stand a lower court ruling that said the Sea Shepherd Conservation Society and founder Paul Watson violated a court order to stop their dangerous protests.

The 9th U.S. Circuit Court of Appeals ruled last year that the transfer of assets and control of Sea Shepherd to Australia and other countries didn't change its 2012 order to the group to cease its dangerous activities. It said the group's U.S. affiliate could be found liable for aiding and abetting the organization's foreign offices to violate the court's injunction.

The Japanese whalers are demanding $2 million in damages and attorney fees.
