The High Court of New Zealand has ruled that Kim Dotcom is eligible for extradition to the United States.
Justice Gilbert ruled that Mr Dotcom and his three co-accused must all be sent to the United States to face trial.
The US wants to trial the three on money-laundering and copyright breaches related to the his website Megaupload.
The United States applied to New Zealand to extradite the four on 13 counts. Extradite means to hand over to another country.
The United States believe that Megaupload was a worldwide criminal organisation that caused an estimated $US500 million loss to copyright holders.
The trial was streamed online and was followed closely both in New Zealand and overseas. The Ministry of Justice’s website crashed, following the public release of the decision.
