The U.S. Supreme Court held that a district court erred in remanding to state court landowners' class action lawsuit seeking compensation for damages they sustained when an energy company allegedly underpaid royalties due under certain oil and gas leases.

The Ninth Circuit upheld a lower court's dismissal of a lawsuit brought under the Alien Tort Statute and California tort law against a petroleum company alleging it should be held liable for war crimes committed by members of the Colombian National Army’s 18th Brigade.
