Definition
A form of municipal government in which the traditional separation of legislative and executive functions is collapsed into a single governing body — a commission — whose members collectively hold both lawmaking authority and administrative responsibility over city departments. In the most common historical model, each elected commissioner serves simultaneously as a legislator (voting on ordinances and appropriations with the full commission) and as the executive head of a specific city department, such as public works, finance, or public safety.
The Bouvier formulation describes commission government as that form of city government in which the mayor is vested with legislative functions and the council is given other than legislative powers — a characterization capturing the structural inversion at the core of the model: functions that constitutional theory assigns to separate branches are deliberately merged.
The Galveston Plan, adopted in Texas after the 1900 hurricane, is the historical prototype. It replaced the conventional mayor-council structure with a small elected commission and spread rapidly through American cities in the early twentieth century before the council-manager model largely displaced it after World War I.

Common Confusion
Commission government is sometimes confused with the council-manager form, but the two are structurally distinct. In the council-manager model, the elected council retains legislative authority and hires a professional city manager to handle executive and administrative functions — preserving a version of separation. Commission government merges legislative and executive roles in the same elected individuals, which is precisely what generated the constitutional litigation reflected in the Bouvier source citation (117 Minn. 458). It is also sometimes loosely confused with government by regulatory commission (such as a public utilities commission or a state administrative commission), which are not municipal governing bodies but rather executive or quasi-judicial agencies exercising delegated authority within a larger governmental structure.

Why It Matters in Research
Commission government is primarily a term of early twentieth century municipal law and political science. Researchers should be aware of several navigational points:
**Temporal concentration.** The commission government movement peaked roughly between 1900 and 1920. Primary sources — charters, enabling statutes, constitutional challenges — cluster in that period. After 1920, the council-manager form began displacing it, and by mid-century commission government had become a minority structure in American cities. Sources from the 1930s onward may discuss commission government in the past tense or as a declining form.
**Constitutional litigation.** The merger of legislative and executive functions in commission government generated a distinct body of state constitutional litigation. State constitutions typically contain separation-of-powers provisions; courts in various states had to determine whether those provisions applied to municipal government at all, and if so, whether commission government violated them. The Minnesota case referenced in Bouvier (117 Minn. 458) represents this line of cases. Researchers working on separation-of-powers questions in municipal context should search for these early twentieth century state court decisions directly.
**Enabling legislation varies.** Commission government was usually authorized by state-specific enabling acts or home rule charters. The powers of commissioners, the structure of the commission, and the role of the mayor differed significantly by state and by city charter. Do not assume uniformity across jurisdictions.
**Terminology overlap.** The word "commission" appears in many governmental contexts — state regulatory commissions, federal agencies, county commissions, charter commissions. In historical sources, context is essential to determine whether "commission government" refers to the specific municipal form described here or to some other commission-based body.
**Connection to the broader municipal corporation literature.** Researchers approaching commission government through the Law Mind corpus should also engage with sources on municipal corporations, home rule, and Dillon's Rule, as the legal validity and scope of commission government powers was often analyzed through those frameworks.

Historical Dictionary Support
Bouvier's Law Dictionary provides the primary historical legal definition available in the corpus, and it is characteristically concise. The entry does two things: it identifies the structural inversion (mayor with legislative functions, council with non-legislative powers) and it immediately signals the constitutional tension by invoking the separation-of-powers doctrine applicable to state government.
The truncated Bouvier text — referencing constitutional provisions dividing government into three departments and prohibiting cross-departmental exercise of power — suggests the entry was drafted with an eye toward the litigation question: does the state separation-of-powers clause apply to this municipal form? This framing reflects genuine legal controversy of the period, not merely academic classification.
Bouvier's treatment is consistent with the broader legal literature of the era, which generally acknowledged commission government as a recognized municipal form while flagging its constitutional novelty. What Bouvier does not address — and what the historical dictionary literature generally underserves — is the administrative and political science analysis of why commission government declined: the practical failure of elected commissioners to function as competent department heads, and the rise of the professional city manager as a superior model for separating politics from administration.

Jurisdictional Note
Legality and structure of commission government depend entirely on state enabling law and individual city charters. Some states never authorized the form; others authorized it through general enabling acts; a few cities retain modified commission structures today. Constitutional validity under state separation-of-powers clauses was litigated on a state-by-state basis with varying results.
