The state of Florida appears to have a strong legal argument for the authorization of the founding and dissolution of cities. However, if you take a step back, the formation of cities is commonly driven by a nucleus of local citizens with a desire for better control of their future. The process is rarely initiated by the state Legislature.
Instead, the state Legislature typically responds to the needs of its constituency by approving or denying a grassroots effort for the formation of a city.
Since the state Legislature is unlikely to initiate an effort for the formation of a city, why would it feel it has the mandate to dissolve a city? Isn’t it more appropriate to leave the question of dissolution of a city to the local needs of the citizenry with the state Legislature serving the process by approving or denying the request?
