The 1986 Proposition 63, titled Official State Language, was a proposition in the state of California on the November 4, 1986 ballot. The ballot initiative created Article III, Section 6 of the California Constitution and made English the official language of the state. The measure passed by a 46.5% margin.[1][2] The amendment:
provides that English is the official language of the state of California; requires the legislature to enforce this provision by appropriate legislation; charges the legislature with preserving and enhancing the role of English as the common language of the state, requiring that no law may be passed that ignores or diminishes this role; and provides for any resident or person doing business in the state to sue the state to enforce these provisions[1]
