1979 - The California Supreme Court ruled that federal preemption does not bar
a nuisance action against a city-owned airport for personal injuries sustained as a result of noise from aircraft using the facility. It also found
that preemption does not bar plaintiffs' claims. Greater Westchester Homeowners' Association v. City of Los Angeles 26 Cal.3d 86. 603 P.2d 1329 160 Cal. Rptr. 733
2000 - Thus, the task of protecting the local population from airport noise has
fallen to the agency, usually the local government, the owns and operates
the airport. Federal Register/Vol.65, No. 136/Friday, July 14, 2000/Notices
Without question, the Code of Federal Regulations states that Congress expressly provided that the proprietary powers and rights of municipal airport
owners are not preemptedby Federal law.
