Robinson Township v. Knoll

Donald and Merle Knoll (defendants) placed a mobile home on their own land within Robinson Township (plaintiff), which had an ordinance confining mobile homes to designated mobile-home parks even though there was no reason the Knolls' land couldn't itself be approved as one. The township sued to force removal of the home, and the Knolls argued the ordinance was unconstitutional as arbitrary and overbroad; the trial court sided with the township, but the appellate court reversed on constitutional grounds, prompting the township's further appeal.
