The Attorney-General is seeking court costs of almost $14,000 from the cameraman at the centre of the "tea tapes" saga.
Bradley Ambrose sought a declaration from the High Court at Auckland as to whether a recording he made of a pre-election conversation between Prime Minister John Key and Act candidate John Banks was legal.
A microphone left on the table where the pair were drinking tea recorded their conversation. Ambrose, a cameraman, denied intentionally recording the conversation and in a sworn affidavit said he did not consider the content of the tape private.
But Mr Key believed the conversation was private and laid a complaint with police against Ambrose, who responded by seeking a declaration from the High Court as to whether the conversation was in fact private.
However, the Chief High Court Judge, Justice Helen Winkelmann, rejected Ambrose's request.
