A group of angry ratepayers is asking the High Court to order the Northland Regional Council to refund rates it illegally set and collected for six years.
In September last year, the High Court in Whangarei ruled NRC rates for Kaipara were not lawfully set or assessed between 2011 and 2016, and that the errors were serious and substantial.
The interim ruling by Justice Ailsa Duffy followed an application for judicial review by the Mangawhai Ratepayers and Residents' Association, its chairman, Bruce Rogan, and his wife, Heather.
In the application the association and the Rogans argued the NRC rates' demand for those years did not state a calendar year by which each instalment of rates was to be paid.
The Rating Act says a local authority must state the financial year to which the rate applies and the date on which it must be paid.
