This one caught my eye as it appears to be relevant when accessing state bills that orride local control government authorities : The Local Fiscal Authority Principle : Home rule should guarantee local fiscal authority and recognize the value of fiscal stability at the local level. This principle accordingly includes local power to raise revenue and manage spending consistent with local budgets and priorities. To support local fiscal authority, a state should ensure adequate intergovernmental aid for general welfare at the local level and be prohibited from imposing unreasonable unfunded mandates.
