City mayor-council government is a form of municipal government in which the power of the mayor is limited to the appointment and dismissal of department heads without council. In a city mayor-council government, the council possesses both legislative and executive authority and has control over the municipal budget. It is the opposite of the city council-manager government. With respect to the budget, the budget is prepared and administered by the mayor in a city mayor-council government. However, such budget must be approved by the city council. While there are some strong-mayor governments, where the mayor appoints a chief administrative officer to supervise department heads, prepare the budget, and coordinate departments.
