Megaupload founder Kim Dotcom faces an extradition hearing after a series of delays caused by a legal action relating to the disclosure of evidence relating to his case.
In May, Dotcom won the right to demand the US Federal Bureau of Investigation (FBI) hands over all the evidence in its online piracy case against him.
Dotcom has been fighting extradition to the US, where he faces charges of conspiracy to infringe copyright, money laundering and defrauding.
The US government has claimed that Megaupload was responsible for its illegally uploaded content and that it gained $175 million from unlawful activities. Dotcom denies any responsibility.
