Most Auckland councillors have been named as defendants in a legal case to stop the possible sale of a public carpark on the city's North Shore.
Miriam Clements has won an interim injunction blocking any sale, while she prepares to seek a High Court judicial review of council decision-making.
Ms Clements is a legal strategist who has lodged cases with the International Criminal Court, and wants carparking and public open space retained in central Takapuna.
Auckland Council has backed plans by its development arm Panuku, to turn a 250-space ground-level carpark into a town square, and relocate parking.
No sale process has yet begun, and no change yet made to the area's planning status.
Ms Clements has named the council and all its politicians barring the mayor, and Councillor Sharon Stewart, in the action.
