The Crown has confirmed it will appeal against the High Court ruling that search warrants used in a police raid on Megaupload founder Kim Dotcom's mansion were unlawful, a media report says.
The German national was arrested after police swooped on his Auckland home in January and stands accused of breaching copyright laws costing owners more than US$500 million. US authorities are attempting to extradite him to face the charges.
Justice Helen Winkelmann found in June that the warrants did not adequately describe the offences to which they related.
"Indeed they fell well short of that. They were general warrants, and as such, are invalid."
The Crown confirmed today it would take the issue to the Court of Appeal, Radio New Zealand reported.
During the initial search of Dotcom's rented mansion, police took dozens of items including anything that could store digital data, meaning home videos, CCTV footage and data from the swimming pool heating system were seized.
Dotcom is facing an extradition hearing in March.
Authorities allege Dotcom and his three co-accused - Mathias Ortmann, Fin Batato and Bram Van der Kolk - used Megaupload and its affiliated sites to knowingly make money from pirated movies and games.
