Kim Dotcom's case is back at the High Court in Auckland on Tuesday.
The hearing is to do with a police raid on the internet entrepreneur's home in January 2012, which culminated in his arrest for internet copyright fraud and the shutdown of his Megaupload site.
The two-day in-chambers hearing is to determine whether some footage can be used as evidence in the case and can't be reported on.
Mr Dotcom and his lawyers are also unable to attend the hearing, as the visual evidence is highly confidential.
Instead an amicus - or friend - to the court has been appointed as an independent lawyer to determine whether the evidence can and should be used.
