A waterfront lobby group faces a huge legal bill after an unsuccessful campaign to block the redevelopment of Wellington's dilapidated Overseas Passenger Terminal.
Waterfront Watch opposed plans for 70 apartments and shops on the site, but lost during resource consent hearings and at a subsequent appeal to the Environment Court.
Developers Willis and Bond say they were invited to apply for costs and told the court they spent $540,000 on lawyers and witnesses.
But they say the amount of money they get, if any, is unlikely to be anything more than a third of the actual expenses.
Waterfront Watch has confirmed it is being asked to pay but won't discuss the case.
Greater Wellington Regional Council is also seeking legal costs from the lobby group.
