On April 22, 2013, the U.S. Supreme Court overturned an appeals court decision that had permitted activists to go forward with a suit claiming that a multinational corporation aided and abetted human rights violations by the governments of Papua New Guinea and Australia, by providing financial support to security forces. The Court directed the appeals court to take a fresh look at the case in light of its ruling last week in Kiobel v. Royal Dutch Petroleum, a case that raised similar issues. The ruling was a victory for WLF, which filed a brief urging the Court to overturn the appeals court decision. WLF argued that federal law does not permit nonresident aliens to file tort suits in federal court based on overseas events having no connection to the United States. WLF noted that the only connection between this suit and the U.S. is that the defendants (Rio Tinto, a group of mining companies based in Australia and Great Britain) conduct a small amount of business in the U.S.
