(a) providing a county charter, or

(b) proposing an amendment or repeal of one or more provisions thereof which would have the effect of transferring a function or duty of the county, or of a city, town, village, district or other unit of local government wholly contained in the county, shall conform to and be subject to consideration by the board of supervisors in accordance with the provisions of this chapter generally applicable to the form of and action on proposed local laws by the board of supervisors. If a county charter, or a charter law as described in this subdivision, is adopted by the board of supervisors, it shall not become operative unless and until it is approved at a general election or at a special election, held in the county by receiving a majority of the total votes cast thereon (a) in the area of the county outside of cities and (b) in the area of the cities of the county, if any, considered as one unit, and if it provides for the transfer of any function or duty to or from any village or for the abolition of any office, department, agency or unit of government of a village wholly contained in the county, it shall not take effect unless it shall also receive a majority of all the votes cast thereon in all the villages so affected considered as one unit. Such a county charter or charter law shall provide for its submission to the electors of the county at the next general election or at a special election, occurring not less than sixty days after the adoption thereof by the board of supervisors. Such a county charter or charter law may provide for the separate submission to the electors at such election of one or more variations of the provisions of such county charter. Any such variation may include, but shall not be limited to, proposed transfers of functions of local government to other units of local government or a class or classes thereof. 8. The form of each proposition submitted to the electors of a county pursuant hereto shall be prepared by the clerk of the board of supervisors with the advice of the county attorney or other principal legal advisor. They also shall prepare a brief abstract of the county charter or charter law so submitted. The form and abstract shall be transmitted to the board of elections of the county. The board of elections, at least twenty days before the election, shall send two or more copies thereof to the clerk of each city, town and village in the county to be made a public record in his office and shall cause a sufficient number of copies to be printed and made available to the electors at the time of registration or otherwise. In addition, such board of elections shall cause a sufficient number of copies to be delivered with the other election supplies and distributed to the electors at the election. The board of elections shall cause each such proposition to be submitted to the electors of the county in the manner provided in the election law and, so far as applicable, in subdivision two of section one hundred two of the county law. Expenses incurred in connection with the submission of any proposition under this article shall be a charge against the county. 9. If two or more propositions having conflicting provisions receive the majorities required for adoption under this section at the same election, the proposition involved in each such conflict which receives the largest affirmative vote shall prevail to the extent of such conflict; but in all other respects such proposition shall be deemed adopted. Where a proposition submitted to the electors of a county under the provisions of this article receives the majority or majorities required for adoption, it shall become operative as prescribed therein, subject to any conditions prescribed therein.
