From the obituary of Lord Jauncey of Tullichettle, in the Independent:

One was the Glasgow fluoride case. The petitioner, who as Jauncey noted in his judgment was herself edentulous, complained about the adding of fluoride by the local authority to the water supply to improve dental health in the community. The hearing on evidence lasted for 201 days. Jauncey was able to dispose of the case in a comparatively short but effective judgment which was not taken to appeal.

The obituary omits the fact that Lord Jauncey suffered MRSA twice in hospital after his stroke in 2005, as the Times online (and no doubt others) reported.
