Twenty years after the bombing, Television New Zealand (TVNZ) sought access to a video record made at the preliminary hearing in which the two French agents pleaded guilty. The footage had remained sealed since shortly after the conclusion of the criminal proceedings. The two agents opposed release of the footage—despite having both written books on the incident—and unsuccessfully took the case to the New Zealand Court of Appeal and, subsequently, the Supreme Court of New Zealand. On 7 August 2006, judges Hammond, O'Regan and Arnold dismissed the former French agents' appeal and TVNZ broadcast their guilty pleas the same day.
