It's also a victory for the citizens of Patea and Waverley, whose council can now move ahead with a positive health action.
At what cost has this victory come?
South Taranaki mayor Ross Dunlop says the legal battle has cost the council at least $300,000 to $350,000, with support from the Ministry of Health.
Water New Zealand puts the cost at upwards of $500,000.
The New Zealand Dental Association has quite rightly called the six-year legal proceedings expensive and unnecessary, a cost to ratepayers and a cost that has also fallen on the Crown.
Dunlop said they had had a request from the local district health board to add fluoride into some extra communities in the district and were just trying to do the right thing, "particularly for young people in our communities with challenges in oral health".
"It turned into a major legal battle, which wasn't our intention."
A lengthy, expensive fight just to do what's right.
Ratepayers and taxpayers should be outraged.
