Kim Dotcom and his co-accused knew the profits from their file-sharing website, MegaUpload, were obtained illegally, the Crown says.
Mr Dotcom, Mathias Ortmann, Bram van der Kolk and Finn Batato face extradition to the United States on charges of copyright infringement, money-laundering and racketeering related to their now-defunct file-storage website MegaUpload. Today is the final day in the case.
The Crown lawyer acting on behalf of the US, Christine Gordon, told the court the men were knowingly obtaining money through infringing copyrights.
She referred to conversations between the co-accused, in which they said most of their income did not come from legitimate users of MegaUpload.
Ms Gordon also said MegaUpload's policy was to delete the links of illegal files when informed of them - rather than removing the file itself.
The Crown needed to show there was a case to prosecute the men in the United States in order for the judge to rule they should be extradited.
