1947. By 1962, the constitution had grown to 75,000 words, which at that time was longer than any other state constitution but Louisiana's. That year, the electorate approved the creation of a California Constitution Revision Commission, which worked on a comprehensive revision of the constitution from 1964 to 1976. The electorate ratified the commission's revisions in 1966, 1970, 1972, and 1974, but rejected the 1968 revision, whose primary substantive effect would have been to make the state's superintendent of schools into an appointed rather than an elected official. The Commission ultimately removed about 40,000 words from the constitution. Provisions The California Constitution is one of the longest in the world. The length has been attributed to a variety of factors, such as influence of previous Mexican civil law, lack of faith in elected officials and the fact that many initiatives take the form of a constitutional amendment. Several amendments involved the authorization of the creation of state government agencies, including the State Compensation Insurance Fund and the State Bar of California; the purpose of such amendments was to insulate the agencies from being attacked as an unconstitutionally broad exercise of police power or inherent judicial power. Unlike other state constitutions, the California Constitution strongly protects the corporate existence of cities and counties and grants them broad plenary home rule powers. The constitution gives charter cities, in particular, supreme authority over municipal affairs, even allowing such cities' local laws to trump state law. By specifically enabling cities to pay counties to perform governmental functions for them, Section 8 of Article XI resulted in the rise of the contract city. Article 4, section 8(d) defines an "urgency statute" as one "necessary for immediate preservation of the public peace, health, or safety"; any proposed bill including such a provision includes a "statement of facts constituting the necessity" and a two-thirds majority of each house is required to also separately pass the bill's urgency section. Many of the individual rights clauses in the state constitution have been construed as protecting rights broader than the Bill of Rights in the federal constitution. Two examples include (1) the Pruneyard Shopping Center v. Robins case involving an implied right to free speech in private shopping centers, and (2) the first decision in America in 1972 which found the death penalty unconstitutional, California v. Anderson, 6 Cal. 3d 628. This noted that under California's state constitution a stronger
