The Charter does not empower the County to exercise exclusively any municipal powers nor to provide for the succession by the County to any property or obligation of any municipality or township without the consent of the legislative authority of such municipality or township. In case of conflict between the exercise of powers granted by this Charter and the exercise of powers by municipalities or townships granted by the Constitution or general law, the exercise of powers by the municipality or township shall prevail. The County shall have power to levy only those taxes that counties are by general law authorized to levy.
