Full Text of § 349.1
Plain-English Summary
Section 349.1 protects the finality of public entity formation and boundary decisions. It covers acts or proceedings taken under color of law for the formation, organization, incorporation, dissolution, consolidation, change of organization, reorganization, or territorial-boundary change of any city, county, city and county, special district, public corporation, other public entity, or an improvement district within one.
The validity of those acts can’t be contested in any action unless the action is brought within six months of the date the acts or proceedings were completed. If no action is filed in time, the formation, dissolution, or boundary change is held valid, legal, and incontestable in every respect. The section doesn’t override any other statute that sets a shorter period for the same kind of challenge.
