Our Water-Our Choice! and Protect Our Waters said in a prepared statement that the high court announced Monday that it will not reconsider the 5-4 decision.
The Sept. 23 ruling said the city’s four-year-old practice of adding fluoride to its drinking water could not be challenged through citizens’ initiatives.
Soon afterward, the groups sought to have the ruling reconsidered.
The statement from the groups said they are “not defeated” but did not state how they plan to continue to challenge fluoridation.
