New Zealand court: Kim Dotcom case simple fraud

Prosecutors outlined their extradition case against Kim Dotcom in a New Zealand court on Thursday, saying the core allegation against the flamboyant Internet mogul accused of multi-million dollar online piracy was fraud.

The case has already dragged on almost four years and been described by the FBI as the biggest copyright investigation in US history, involving leading-edge technology and huge sums of money.

But barrister Christine Gordon, representing US authorities who want Dotcom deported to stand trial in America, said the accusations against him were not complicated.

"In the long prelude to this hearing, much has been said about the novelty and technicality of the case," Gordon told the Auckland District Court.

"When distractions are stripped away, the evidence boils down to a simple scheme of fraud... the dishonesty at the core of Megaupload's operations may be expressed in straightforward terms."

Gordon said Dotcom had admitted his culpability in a Skype conversation that was monitored by US authorities during their lengthy investigation.

"At some point, a judge will be convinced about how evil we are and then we're in trouble," she quoted him as saying.

The United States launched its bid to extradite Dotcom shortly after New Zealand police arrested him in January 2012 during a dramatic dawn raid on his Auckland mansion.

The hearing has been delayed numerous times but judge Nevin Dawson ruled on Thursday that it would finally go ahead, rejecting applications for a stay of proceedings.

Gordon said Megaupload, the now-defunct site at the heart of Dotcom's online empire, was part of a scheme to steal copyright-protected material.

"The respondents took part in a conspiracy," she said.

"They deliberately introduced copyright-infringing material to their website, they deliberately preserved that material, they deliberately took steps to profit from that material and made vast sums of money."

The website was an early example of cloud computing, allowing users to upload large files onto a server so others could easily download them without clogging up their email systems.

At its height in 2011, Megaupload claimed to have 50 million daily users and account for four percent of the world's Internet traffic.

An FBI indictment alleges 90 percent of material on the site was copyright protected.

It claims Megaupload netted more than $175 million in criminal proceeds and cost copyright owners $500 million-plus by offering pirated content.

Dotcom, a German national who moved to New Zealand in 2010, denies any wrongdoing, saying he is a legitimate internet entrepreneur.

The 41-year-old and his three co-accused -- ex-Megaupload executives Finn Batato, Mathias Ortmann, and Bram van der Kolk -- face charges including fraud, racketeering and money laundering.

They risk jail terms of up to 20 years if convicted in a US court.

But first the Auckland court needs to decide if there is sufficient evidence to extradite them to the United States.

The extradition hearing -- expected to last at least three weeks --  will resume on Friday.
