§ 50. Transfers of appropriations. Notwithstanding any other provisions of law, in order to better coordinate and reorient the administration of programs which help to reduce, eliminate or avoid financial dependency, in order to assure that services provided under such programs are delivered in the most economical and efficient fashion, and in order to fully qualify such programs for federal assistance, the director of the budget may approve contracts between the state department of social services and other state departments and agencies which may be providing such services to individuals and families who are receiving or who are former or potential recipients of public assistance and care, as defined by the rules and regulations of the state department of social services. Such contracts may provide for the delivery of such services on behalf of the state department of social services and the social services districts of the state, to the extent feasible, upon a finding by the director of the budget that such contractual arrangements would be to the advantage of the state in respect to Federal reimbursement and the orderly and effective provision of such services. The fiscal benefit of any federal financial assistance realized by the state pursuant to such contracts will be shared with any localities which contribute to the costs of providing the contractual services, according to the proportion by which such costs are shared between the state and localities pursuant to law, on the day immediately preceding the execution date of such contracts. Notwithstanding any other provisions of law, the director of the budget is hereby authorized to transfer such funds as may be necessary to give effect to any such contractual arrangements authorized under this section to the state department of social services from funds appropriated to any such other state departments and agencies to the extent that such transfers may be necessary to obtain federal reimbursements for the provision of services of the same nature as those for which such funds were appropriated and any funds so transferred shall be deemed to have been appropriated to the state department of social services for the purposes of providing for such services and obtaining federal reimbursement for their support. No such transfer shall take effect until a certificate of transfer shall have been issued by the director of the budget and copies filed with the state comptroller, the chairman of the senate finance committee and the chairman of the assembly ways and means committee. Amendments to such certificates may be made by filing revised copies with the same officers. Every such certificate shall clearly show (1) the items and amounts of appropriations which are to be transferred, (2) the chapter of the laws in which they were originally appropriated, and (3) the department or agency from which they are being transferred.
