``What we are dealing with is an extreme saga of incompetence in public decisions making. Ratepayers have persisted in pursuing and trying to hold their elected representatives and their managers to account and have been frustrated at very turn in trying to do that,'' Mr Palmer said.
Ratepayers were initially told the final scheme would cost no more than $10.8 million in 2003, then $37 million in 2009 while at the same time the council had taken out a loan for $57.978 million for the scheme and Mr Palmer said this was not done with public consultation as required by law. The spending was also not included in the council's long term plan, as required.
He said the group wanted the court to rule that the council doesn't have and didn't have the power to set rates to cover the loans taken out for the scheme that have been ruled illegal.
More than 100 Mangawhai residents were at the court for the hearing - which is due to last at least until Wednesday - with proceedings screened live in a neighbouring courtroom so all the residents could watch the action.
