§ 73. Power of the board of supervisors to change the administrative system of the county social services district. When pursuant to section seventy-two, the board of supervisors has adopted a resolution directing that the cost of all public assistance and care shall be a charge on the county social services district: 1. The county social services district shall, after the date fixed by such resolution, be responsible for administration of public assistance and care in all of the towns of its district and thereafter all provisions of this chapter as to the powers and duties of towns and of town social services officers shall be inoperative in such county social services district. The appointment of all town social services officers and employees shall terminate on the date when such resolution takes effect. 2. (a) Such resolution shall not take effect in a city in a county social services district unless it is confirmed by act of the legislative body of the city in accordance with the provisions of this paragraph. The legislative body of such a city may confirm the resolution of the board of supervisors (1) on or before the first day of October in the year in which such resolution was adopted by the board of supervisors, and make such confirmation effective on the first day of January next succeding such confirmation, provided the resolution of the board of supervisors takes effect in the towns of the county on or before such first day of January, or (2) at any other time or date, and make such confirmation effective on any date not earlier than the date the resolution of the board of supervisors takes effect in the towns of the county, provided the board of supervisors shall by resolution specifically approve such confirmation.

(b) On the day after a city confirms a resolution of the board of supervisors pursuant to paragraph (a), the mayor or the city clerk shall send a written notice of such confirmation to the clerk of the board of supervisors of the county. He shall also send a copy of such notice to the county commissioner of social services and the county commissioner shall thereupon notify the department.

(c) If a city in the county social services district shall confirm the resolution of the board of supervisors in accordance with the provisions of paragraph (a), the county social services district shall, on and after the effective date of such confirmation be responsible for administration of public assistance and care in such city, and thereafter all provisions of this chapter as to the powers and duties of a city in a county social services district and of city social services officers shall be inoperative in such city.

(d) Unless and until a city in the county social services district shall confirm the resolution of the board of supervisors in accordance with the provisions of paragraph (a), the responsibility of such city for assistance and care in its territory shall not be affected by such resolution, and the city shall be governed by the provisions of this chapter and other laws relating to cities which form part of a county social services district and to city social services officers; and the city shall continue to be responsible for the cost of public assistance and care under the provisions of subdivision two of section sixty-nine, except as otherwise provided in title three-a of this article. The cost of any assistance and care given to local charges residing or found in such city, paid by the county social services district under the provisions of subdivision three of section sixty-nine, shall be a charge on the county social services district. 3. The board of supervisors shall make such additional appropriations and authorize the appointment of such number of deputy commissioners, other assistants and employees as it may deem necessary to provide adequate administration of the public assistance and care for which the county social services district is made responsible under the provisions of this section.
