Richard James Williamson, R (on the application of) v Caerphilly County Brough Council

The defendant failed to apply the correct legal test by not considering whether the cat fouling constituted deposits prejudicial to health under section 79(1)(e) of the Environmental Protection Act 1990, and instead focused on irrelevant common law principles and the manner in which the cats were kept. The fouling was capable of amounting to a deposit prejudicial to health and should have been properly investigated, including consideration of health risks. The determination cannot stand and must be redetermined in accordance with statutory principles.
