Plaintiffs-Appellants (the “plaintiffs”), twenty-two Argentinian residents, bring suit against DaimlerChrysler Aktiengesellschaft (DCAG) alleging that one of DCAG’s subsidiaries, Mercedes-Benz Argentina (MBA) collaborated with state security forces to kidnap, detain, torture, and kill the plaintiffs and/or their relatives during Argentina’s “Dirty War.”…The only question before us is whether the district court had personal jurisdiction over DCAG. The district court granted DCAG’s motion to dismiss the case for lack of such jurisdiction. We conclude, however, that DCAG was subject to personal jurisdiction in California through the contacts of its subsidiary Mercedes-Benz USA (MBUSA). We hold that MBUSA was DCAG’s agent, at least for personal jurisdictional purposes, and that exercise of personal jurisdiction was reasonable under the circumstances of this case.
