For the purposes of this act, a "general law" shall be deemed to be such law or part thereof, heretofore or hereafter enacted, that:
Nothing in this act shall be construed to prevent counties from abolishing or consolidating agencies the existence of which has heretofore been mandated by State statute providing that such abolition or consolidation shall not alter the obligation of the county to continue providing the services previously provided by such abolished or consolidated agency.
The intent of this act is to enable a county that has adopted a charter pursuant to this act to cause any duty that has been mandated to it by the Legislature to be performed in the most efficient and expeditious manner, and, absent a clear legislative declaration to the contrary, without regard to organizational, structural or personnel provisions contained in the legislation mandating such duty.
