The theory of state preeminence over local governments was expressed as Dillon's Rule in an 1868 case: "Municipal corporations owe their origin to, and derive their powers and rights wholly from, the legislature. It breathes into them the breath of life, without which they cannot exist. As it creates, so may it destroy. If it may destroy, it may abridge and control". By contrast, the
Cooley Doctrine, or the doctrine of
home rule, expressed the theory of an inherent right to local
self-determination. In a concurring opinion, Michigan Supreme Court Judge
Thomas M. Cooley in 1871 stated, "local government is a matter of absolute right; and the state cannot take it away". In
Municipal Corporations (1872), Dillon contended that in contrast to the powers of states, which are unlimited but for express restrictions under the state or federal constitution,
municipalities only have the powers that are expressly granted to them by the state, any power necessarily implied by an express power, and those powers essential to a municipality's existence. This formulation of the scope of municipal power came to be known as "Dillon's Rule". The
Supreme Court of the United States cited
Municipal Corporations and fully adopted Dillon's emphasis on state power over municipalities in
Hunter v. Pittsburgh, which upheld the power of
Pennsylvania to consolidate the city of
Allegheny into the city of
Pittsburgh, despite the objections of a majority of Allegheny's residents. The Court's ruling that states could alter or abolish at will the charters of municipal corporations without infringing upon contract rights relied upon Dillon's distinction between public, municipal corporations and private ones. However, the Court did not prevent states from passing legislation or amending their
constitutions to explicitly allow home rule. This constitutional allowance was reiterated in
Trenton v. New Jersey, where the Supreme Court held that "In the absence of state constitutional provisions safeguarding it to them, municipalities have no inherent right of self-government which is beyond the legislative control of the state, but are merely departments of the state, with powers and privileges such as the state has seen fit to grant, held and exercised subject to its sovereign will". ==References==
