An anonymous reader writes "You may recall that the US government, mainly through Homeland Security's Immigration and Customs Enforcement division (ICE) has been seizing domain names over the past year, based on bad evidence, even leading to the 'accidental' seizure of 84,000 sites. While it has taken some time, the first challenge has been filed to the domain seizures, by the company Puerto 80, who runs Rojadirecta, a Spanish internet forum that was seized because users linked to streaming sporting events. Rojadirecta was declared perfectly legal (twice!) in Spain, but the challenge obviously focuses on US law, and how the seizure was improper and did not meet the qualifications for a seizure, how the seizure violates the First Amendment by being improper prior restraint on protected speech, and how Rojadirecta is not guilty of criminal copyright infringement. This could represent a very important case in determining the government's legal right to simply seize domain names."
