The Pirate Party is planning to launch legal proceedings against the FBI in retaliation for shutting down Megaupload, a popular file-sharing site that has been accused of being a haven for pirated content.

Megaupload was closed by the US Department of Justice and the Federal Bureau of Investigation on 19 January and no content has been accessible since.

A statement on Pirata.ca claims that closure of Megaupload has impeded the access to millions of archives of non-infringing content, and accuses the FBI of violating Articles 197 and 198 of the Spanish Penal Code by misappropriating personal data.

"The widespread damage caused by the sudden closure of Megaupload is unjustified and completely disproportionate to the aim intended," the statement said.

"For this reason Pirates of Catalonia, in collaboration with Pirate Parties International and other Pirate Parties (including the Pirate Party of the UK), have begun investigating these potential breaches of law and will facilitate submission of complaints against the US authorities in as many countries as possible, to ensure a positive and just result."
