The level of autonomy of local government in the United States is governed by state constitutions. However, the way in which it is regulated is inconsistent and raises interpretative doubts. The analysis includes two dimensions of local autonomy, i.e. the formal dimension (the procedure for its enactment into state law) and material dimension (subjective scope of its operation). It is preceded by an indication of constitutional foundations (the principle of federalism) and of doctrinal backgrounds (formulated in judicial decisions made in the 19th century) of the current position of local governments in their relations with state authorities. This position has evolved towards greater autonomy of local authorities, refl ected in the widespread acceptance of home rule doctrine. However, the implementation of the doctrine in the provisions of state law takes the form which can hardly be considered to be real strengthening of the position of local government in its relations with the state.
