Megaupload cannot be brought within the jurisdiction of a federal court in Virginia for criminal proceedings without its consent, as federal rules do not contemplate service of a criminal summons on a wholly foreign corporation without an agent or offices in the US, its lawyers said in a filing on Wednesday.

The move to get the court to dismiss the criminal case against the Hong Kong based file-sharing site comes a day after a court in Auckland ruled that Megaupload founder, Kim Dotcom, should be allowed access to documents that contain evidence against him, held by prosecutors in the US and New Zealand.

Dotcom and colleagues, and two companies including Megaupload, were indicted by a grand jury in the Eastern District of Virginia on 5 January, and charged with engaging in a racketeering conspiracy, conspiring to commit copyright infringement and money laundering, and two substantive counts of criminal copyright infringement, according to the US Department of Justice.

Dotcom and colleagues Finn Batato, Mathias Ortmann and Bram van der Kolk were arrested in Auckland by New Zealand authorities, who executed provisional arrest warrants requested by the US.

The US has filed in Auckland for the extradition of Dotcom and three other colleagues, which comes up for hearing on 6 August.

No arrest warrant or summons for the corporation itself

Although the government obtained warrants from the federal court in Virginia for the arrest of Dotcom and six others, it did not obtain an arrest warrant nor request a summons for Megaupload, according to a proposed motion before the US District Court for the Eastern District of Virginia, Alexandria division.

Counsels for Megaupload filed Wednesday for leave to enter a limited and special appearance on behalf of Megaupload to file the motion. The counsels have also asked leave to enter a motion to release assets of the defendants frozen by the US to pay for their defence.

"It is thus apparent that on 5 January 2012, the Government saw fit to indict Megaupload, seize all its assets, and force the company into extinction without serving - or even attempting to serve - the company in any way, shape or form," Megaupload's lawyers have said in the proposed motion to the court.

Megaupload's argument turns around rule 4 of the Federal Rule of Criminal Procedure which is said to pose a hurdle to serving a corporation that resides on foreign soil as it requires that "a summons is served on an organisation by delivering a copy to an officer, to a managing or general agent, or to another agent appointed or legally authorised to receive service of process."

Megaupload has no offices or agents in the US

The second part of the rule also requires that a copy of the summons "must also be mailed to the organisation's last known address within the district or to its principal place of business elsewhere in the United States."

To date, the government has not served a summons on any officer or agent of Megaupload, according to the proposed motion, as Megaupload does not have any officers or authorised agents for service of process in the US, according to the motion.

As Megaupload does not have an office in the US, nor has it had one previously, the service of a criminal summons on Megaupload is therefore impossible, which forecloses the government from prosecuting Megaupload, the counsels have argued in the filing.

Even if Dotcom is extradited to the US, the government cannot properly serve Megaupload, because the second part of rule 4 will still not be satisfied.

The court should dismiss the indictment against Megaupload to prevent any further injustice, according to the filing. US officials were not immediately available for comment.
