Road tolls opponent Hans Grueber has lost a High Court appeal against convictions for using Auckland's Northern Gateway motorway without paying for the privilege.
Dr Grueber, 73, alleged in court this month that the former Transit New Zealand had used a "bogus survey" to gain ministerial approval for a tolling scheme on the basis that there was a high degree of support for it from affected communities.
He said Transit, which evolved into the Transport Agency in 2008, cast its net too far in surveying residents of Whangaparaoa Peninsula after submissions from residents closer to the 7.5-kilometre motorway route north of Orewa showed divided views.
But Justice Geoffrey Venning, in a reserved decision issued today, has ruled such a "collateral" challenge to four convictions entered against Dr Grueber in North Shore District Court two and a half years ago was not available to the Waiwera resident.
He said the Transport Agency, as the prosecuting authority, was removed from and had no relationship to the decision in 2004 of then Transport Minister Pete Hodgson to make a recommendation to the Governor-General of the day, Dame Silvia Cartwright, to establish the toll road.
