Under any consistent application of the theory of democracy a city would be entitled to the fullest measure of local self-government. It ought to be given an absolutely free hand to initiate and carry out any policies of purely local concern. This right, however, the American city does not possess. Local self-government is recognized neither in theory nor in practice under our political scheme. The true local unit is the city, and this, according to our legal and constitutional theory, is merely the creature of the state legislature. The latter called it into being, determines what powers it may exercise, and may strip it of them at pleasure. According to the prevailing practice of our state legislatures and the almost uniform decisions of our courts the exercise of local self-government by our cities is to be regarded as a mere privilege and not a right. The municipal charter was originally a grant of certain privileges of local government in return for money payments or other services rendered to the king. It was a mere concession of privileges based upon expediency, and not a recognition on the part of the Crown of local self-government as an admitted right. As an express and formal statement of the measure of local government which the king would bind himself to respect, it tended to limit his power of interference in matters covered by such charter, since privileges solemnly granted could not with safety be lightly and arbitrarily disregarded. Municipal charters thus have the same origin as the constitution of the state itself, in that they are the outcome of an effort to place a check upon an irresponsible central authority. The legislature of the American commonwealth in succeeding to the power of the king over municipal charters manifested at first an inclination to concede to the city the right to a measure of local self-government. Thus "the city of New York received from the English kings during the colonial period a charter which, on the Declaration of the Independence of the colony of New York, and the establishment of the new state of New York, was confirmed by the first Constitution of the state. For a considerable period after the adoption of this constitution, changes in that charter were made upon the initiation of the people of the city, which initiation took place through the medium of charter conventions whose members were elected by the people of the city, and no statute which was passed by the legislature of the state relative to the affairs of the city of New York took effect within the city until it had been approved by the city."[160]
