Warrants to raid Kim Dotcom's Auckland mansion that were later found illegal were "clumsy" but not so broad they were invalid, the Court of Appeal has been told.
The Crown is appealing against the High Court's ruling last year that the search warrants were too generic and did not adequately describe the offences they were related to.
In the High Court, Chief High Court Judge Justice Helen Winkelmann also ruled the removal from New Zealand of cloned hard drives seized from the Dotcom mansion was unlawful.
Opening the Crown case in the Court of Appeal in Wellington this morning, lawyer David Boldt agreed there were errors in the warrants.
"The Crown does not shrink from the fact that these warrants contained some errors."
