Kim Dotcom has confirmed he will appeal a ruling that search warrants used to raid his mansion were lawful.
The Court of Appeal yesterday overturned an earlier High Court decision that the warrants were too broad.
The appeal court judges found there was enough information accompanying the warrants to make it clear what the police were looking for.
However, they ruled that a decision to send copies of material seized to the United States authorities was illegal.
The internet businessman confirmed on Twitter that his legal team will seek leave to appeal the search warrant decision to the Supreme Court.
A spokesperson for the Attorney-General, Chris Finlayson, says crown lawyers have not decided yet whether to appeal the ruling on the seized material.
