Associated Home Builders of the Greater Eastbay, Inc. v. City of Livermore

Livermore (defendant) halted new residential building permits until local schools, sewage disposal, and water supply met specified standards, stating the ordinance served public health, safety, welfare, and air-pollution goals; Eastbay (plaintiff), a homebuilders' association, challenged the ordinance as an unconstitutional exercise of police power that improperly burdened nonresidents' right to migrate, without presenting evidence the ordinance was actually unrelated to its stated objectives.
