Dillon's Rule
A legal principle holding that cities have only those powers explicitly granted to them by the state legislature, the opposite of home rule.
How It Works
Named after Iowa Supreme Court Justice John Forrest Dillon, who articulated the doctrine in the 1868 case City of Clinton v. Cedar Rapids and Missouri River Railroad Co. and in his influential 1872 Treatise on the Law of Municipal Corporations, Dillon's Rule restricts cities to powers that are (1) expressly granted by the state legislature, (2) necessarily implied from those grants, or (3) essential to the declared purposes of the city. Any ambiguity is resolved against the city. The U.S. Supreme Court endorsed the doctrine in Hunter v. City of Pittsburgh (1907), describing municipal corporations as "created as convenient agencies for exercising such of the governmental powers of the state as may be entrusted to them." States that follow strict or modified Dillon's Rule include Virginia, North Carolina, South Carolina, Alabama, Tennessee, Kentucky, Mississippi, Arkansas, Nebraska, Idaho, West Virginia, Wyoming, and Vermont. Under strict Dillon's Rule, a city cannot impose a new tax, adopt a new fee, regulate a new activity, or structurally reorganize its departments without explicit state authorization, typically requiring a special act of the legislature. Virginia's 41-city special legislation requirement is a classic example. This limits fiscal flexibility and forces cities to lobby state legislatures for authority to address local problems: when Nashville sought to enact local nondiscrimination protections in 2011, the Tennessee state legislature pre-empted the ordinance; similar pre-emption dynamics have played out around short-term rental, minimum wage, and plastic bag policies. Dillon's Rule cities face tighter revenue and service-delivery constraints during economic downturns because they cannot quickly adopt new revenue sources. The National League of Cities and ICMA have long advocated broadening home rule protections. Fiscal flexibility under Dillon's Rule affects the 10% revenue diversity and 10% trend direction factors of the CitySpend Fiscal Health Score.
