A High Court judge has ruled that local authorities have the legal right to fluoridate drinking water.
Anti-fluoride group New Health New Zealand had sought a judicial review of the South Taranaki District Council's decision to add fluoride to Patea and Waverley's drinking water.
It alleged the council had no legal power to do so, and the decision breached the right to refuse medical assistance. But in a decision released yesterday, Justice Rodney Hansen rejected the group's claims.
He concluded that water fluoridation was not a medical treatment, and did not differ fundamentally from other public health interventions aimed at a wider population, such as water chlorination or the addition of iodine to salt.
Lawyer Duncan Laing, who acted for the council, said the decision could set a precedent for other local authorities considering fluoridation.
