City of Oroville v. Superior Court

(Supreme Court of California) – Reversed. A dental practice contended that the City of Oroville was liable under an inverse condemnation claim because of damage suffered when raw sewage began overflowing from toilets, sinks, and building drains. The lower court found that the city was liable. The Supreme Court disagreed, stating that the dentist could not prove that the damage was substantially caused by the design, construction or maintenance of the sewer system and that the damage could have been prevented if dentists had installed a legally required backwater valve.
