In its filing Monday, Yahoo outlines several reasons for the dismissal of the case. It argues that litigating the case "risks violating international law principles of sovereignty, interfering with U.S. foreign policy, and jeopardizing the U.S. law enforcement interests."

Yahoo also argues that the plaintiffs have failed to state a claim under the Alien Tort Statute, the Torture Victim Protection Act, the Electronic Communications Privacy Act (ECPA), and the California laws on which they rely.

Moreover, the plaintiffs' claims contravene federal, California, and international law, which protect defendants from civil liability for communicating with law enforcement officials regarding investigations, according to Yahoo.

In their amended complaint, filed July 30, the plaintiffs allege Yahoo and Yahoo Hong Kong violated a series of U.S. and international laws, including torture, arbitrary arrest, prolonged detention, and forced labor as a violation of the international Alien Tort Statute and the Torture Victim Protection Act. They also allege violation of the California Business and Professional Code for unfair business practices and violation of the Electronic Communications Privacy Act for unlawful access to stored communications.

The plaintiffs seek, among other things, awards of a variety of damages; declaration that defendants violated international law; a requirement that defendants actively help to secure the release of detained plaintiffs; and an injunction barring the defendants from "any further disclosures of user information" to prevent future abuses.

The complaint states that Wang Xiaoning was arrested and unlawfully and arbitrarily detained and prosecuted for publishing and circulating through the Internet electronic journals and articles that supported democratic reform in China and for communicating with other democracy advocates.

"He is serving a ten-year sentence at Beijing Municipal No. 2 Prison, a forced labor prison for political prisoners, under severe conditions of prolonged confinement that are highly abusive in nature. He has served almost four years of his ten-year sentence, and has been imprisoned for almost five years," the complaint reads.

Meanwhile, Shi Tao was arrested and unlawfully and arbitrarily detained and prosecuted for e-mailing messages, notes, and journalistic dispatches describing government restrictions on journalists imposed in connection with the 15th anniversary of the Tiananmen Square crackdown on democracy advocates, according to the complaint.

"He currently is serving the third year of a 10-year sentence for 'divulging state secrets abroad' at Chishan Prison of Hunan Province, a high-security prison with a documented system of forced labor and torture, and has been in detention for almost four years," the complaint reads.

Their arrests and detainment of these two Chinese citizens were "inflicted upon" them as a result of Yahoo and Yahoo Hong Kong's actions to aid and abet Chinese government officials "in committing these major human rights abuses," the complaint reads.

The judge will hold a hearing on Yahoo's dismissal request on November 1st at 2 p.m. Pacific Time.
