The Mangawhai Ratepayers and Resident's Association chairman said the council's decision was not surprising.
"John Robertson is part of the other side which is dedicated to protecting the vested interest of government's friends that are the big multinationals and banks," association chairman Bruce Rogan said.
The council has so far filed legal proceedings against former chief executive Jack McKerchar and the Auditor General over the scheme that ended up costing ratepayers about $57 million.
In August, commissioners running the council voted to pursue Mr McKerchar through the courts for his handling of the "botched" system that was initially estimated to cost $10.8 million.
Papers were filed about a week before Christmas last year against Mr McKerchar in the Employment Relations' Authority and against Auditor General Lyn Provost in the High Court.
The Kaipara District Council (Validation of Rates and Other Matters) Bill which was passed in December 2013 legalised council bungles which contributed to the debt blowout and led the Government to appoint commissioners in 2012 to replace the council.
