Kim Dotcom wins access to evidence seized in raid

A New Zealand court has granted Megaupload founder Kim Dotcom access to all evidence seized by police in a 2012 raid, bolstering the internet entrepreneur's fight against extradition to the United States to face online piracy charges.

Repeating its decision that warrants used in the raid on Dotcom's home were illegal, the High Court ruled that police must provide copies of evidence considered relevant to the US investigation. These include materials forwarded to the Federal Bureau of Investigation.

Any evidence seized in the raid, including computers, hard drives, files, and other materials deemed irrelevant must be returned to the founder of the shuttered file-sharing site.

"The police are to review digital data storage devices and return any to the plaintiffs that contain no relevant material," Justice Helen Winkelmann said in a statement. Police, she said, may retain other storage devices but had to "provide a clone of those devices to the plaintiffs".

Acting on a request from US authorities, New Zealand police arrested Dotcom and three colleagues.

Dotcom's lawyers have argued that lack of access to the seized evidence put them at a disadvantage in defending the German national and his colleagues against extradition.

The United States has launched a criminal investigation into Megaupload, arguing that it facilitated online piracy, and participated in racketeering and money laundering.

Dotcom, who has New Zealand residency, says the site was merely a storage facility for online files and should not be held accountable if stored content was obtained illegally.

An extradition hearing is scheduled for August, but may be delayed due to separate cases linked to another court ruling that unlawful warrants were used in the police raid.

The copyright case could set a precedent for Internet liability laws and, depending on its outcome, may force entertainment companies to rethink their distribution methods.

The US Justice Department says Megaupload cost copyright holders such as movie studios and record companies more than $US500 million and generated more than $US175 million in criminal proceeds. It described the case as being among the largest ever involving criminal copyright.

Dotcom launched a new file-sharing service, Mega, in January.
