The Text

There shall be in each county, except in a county wholly included in a city, a board of supervisors, to be composed of such members and elected in such manner and for such period as is or may be provided by law. The legislature may provide by law for forms of government for the counties of Westchester and Nassau, or either, subject to adoption and approval by the electors of any such county at a general election in an odd-numbered year. Any such form of government may include the transfer to the county or to county officers of any functions now exercised by towns or town officers. The law providing for such form of government shall also prescribe the manner in which the county affected may subsequently abandon it, and revert to its former form of government. The adoption of such form of government by the county shall not preclude the legislature from amending or modifying such plan. If under such form of government the board of supervisors be abolished, the powers and duties of t he board of supervisors, as prescribed by the constitution, or by statute if not provided for by such form of government, shall devolve upon the governing elective body in such county. In a city which includes an entire county, or two or more entire counties, the powers and duties of a board of supervisors may be devolved upon the municipal assembly, common council, board of aldermen or other legislative body of the city.
