In a move that legal experts said could present a major test of First Amendment rights in the Internet era, a federal judge in San Francisco on Friday ordered the disabling of a Web site devoted to disclosing confidential information.The site, Wikileaks.org, invites people to post leaked materials with the goal of discouraging “unethical behavior” by corporations and governments. It has posted documents said to show the rules of engagement for US troops in Iraq, a military manual for the operation of the prison at Guantanamo Bay, Cuba, and other evidence of what is has called corporate waste and wrongdoing.The case in San Francisco was brought by a Cayman Islands bank, Julius Baer Bank & Trust. In court papers, the bank claimed that “a disgruntled ex-employee who has engaged in a harassment and terror campaign” provided stolen documents to Wikileaks in violation of a confidentiality agreement and banking laws. According to Wikileaks, “the documents allegedly reveal secret Julius Baer trust structures used for asset hiding, money laundering and tax evasion”. On Friday, Judge Jeffrey S White of US District Court in San Francisco granted a permanent injunction ordering Dynadot, the site’s domain name registrar, to disable the Wikileaks.org domain name. The order had the effect of locking the front door to the site — a largely ineffectual action that kept back doors to the site, and several copies of it, available to sophisticated Web users who knew where to look. Domain registrars like Dynadot, Register.com and GoDaddy.com provide domain names — the Web addresses users type into browsers — to website operators for a monthly fee. White ordered Dynadot to disable the Wikileaks.org address and “lock” it to prevent the organization from transferring the name to another registrar. The feebleness of the action suggests that the bank, and the judge, did not understand how the domain system works, or how quickly Web communities will move to counter actions they see as hostile to free speech online. The site itself could still be accessed at its Internet Protocol address (88.80.13.160/) — the unique number that specifies a Web site’s location on the Internet. Wikileaks also maintained “mirror sites,” or copies usually produced to ensure against failures and this kind of legal action. Some sites were registered in Belgium (wikileaks.be/), Germany (wikileaks.de) and the Christmas Islands (wikileaks.cx) through domain registrars other than Dynadot, and so were not affected by the injunction. Fans of the site and its mission rushed to publicize those alternate addresses this week. They have also distributed copies of the bank information on their own sites and via peer-to-peer file sharing networks.In a separate order, also issued Friday, White ordered Wikileaks to stop distributing the bank documents. The second order, which the judge called an amended temporary restraining order, did not refer to the permanent injunction but may have been an effort to narrow it.Lawyers for the bank and Dynadot did not respond to requests for comment. White has scheduled a hearing in the case for February 29.
