New submitter d18c7db writes "Internet tycoon Kim Dotcom has won another court victory, today given the right to drag the secretive GCSB into the spotlight of a courtroom. Forcing the GCSB to be tied to the court action opens it up to court ordered discovery — meaning Dotcom's lawyers can go fishing for documents as they continue to fight extradition to the U.S. to face copyright charges. But the GCSB claimed any disclosure of what [was] intercepted would prejudice New Zealand's national security interests 'as it will tend to reveal intelligence gathering and sharing methods.' Dotcom and his fellow Mega Upload accused asked Chief High Court Judge Helen Winkelmann for the right to have the GCSB become part of the proceedings, amend their statement of claim, and for additional discovery. In a judgment issued today she gave that permission."
