Wyoming State Constitution: Key Provisions and History

The Wyoming State Constitution establishes the foundational legal framework for state government, defining the structure, powers, and limitations of all three branches. Ratified in 1889 concurrent with Wyoming's admission to the Union as the 44th state, it remains the supreme law of the state, superseded only by the U.S. Constitution and federal law. Researchers, legal practitioners, and public administrators reference this document to interpret the boundaries of legislative authority, executive power, and individual rights within Wyoming.

Definition and scope

The Wyoming State Constitution is the organic law of Wyoming, consisting of 21 articles that address everything from the bill of rights to the structure of county governments. The document operates within a dual sovereignty framework: Wyoming law governs state matters, while federal constitutional supremacy applies wherever the two conflict under the Supremacy Clause (U.S. Constitution, Article VI).

Scope and coverage: This page addresses the Wyoming State Constitution exclusively. It does not cover federal constitutional provisions, tribal law applicable to the Wind River Reservation, or municipal charters adopted independently by Wyoming cities and towns. Adjacent matters such as Wyoming elections and voting and Wyoming public records access are governed by statutes that derive authority from constitutional provisions but are not themselves constitutional text.

The constitution contains 97 sections across its core articles as originally ratified, with additional amendments adopted over subsequent decades through the legislative referral process defined in Article 20. Amendments require passage by two-thirds of each legislative chamber and ratification by a majority of Wyoming voters at the next general election (Wyoming Constitution, Art. 20, §1).

How it works

The constitution distributes governmental authority across three co-equal branches, each defined in discrete articles:

  1. Legislative Branch (Article 3): A bicameral legislature consisting of the Senate (30 members) and House of Representatives (60 members). The Wyoming State Legislature holds exclusive authority to enact statutes, appropriate funds, and propose constitutional amendments.
  2. Executive Branch (Article 4): Vests executive power in the Governor, whose office is detailed on the Wyoming Governor's Office reference page. Separately elected constitutional officers include the Secretary of State, State Treasurer, State Auditor, and Attorney General.
  3. Judicial Branch (Article 5): Establishes the Wyoming Supreme Court as the court of last resort, with 5 justices selected through a merit-based appointment and retention election system rather than partisan election.

Article 1 functions as Wyoming's bill of rights, containing 38 sections that enumerate individual protections including due process, equal protection, and the right to bear arms. Article 1, §36, added in 2012, explicitly declares water a state resource held in trust — a provision with direct operational significance for water rights administration.

The amendment process under Article 20 contrasts with the U.S. constitutional model in one critical respect: Wyoming requires no convention ratification. Voter approval at a general election is sufficient. This has produced a more frequently amended document than the federal constitution.

Common scenarios

Constitutional provisions are invoked in identifiable, recurring contexts across state government operations:

Litigation before the Wyoming Supreme Court frequently centers on Articles 1, 3, and 15 — the bill of rights, legislative powers, and taxation — with judicial interpretations binding on all lower courts and administrative agencies statewide.

Decision boundaries

Understanding what the Wyoming State Constitution governs — and what it does not — prevents misapplication in administrative and legal contexts.

Constitution governs:
- Structural authority of all three branches of state government
- Individual rights enforceable against state actors
- Limitations on legislative power, including debt ceilings and appropriation requirements
- The amendment process for the constitution itself

Constitution does not govern:
- Procedural matters delegated entirely to statute (e.g., specific procurement rules under Wyoming government contracts and procurement)
- Federal agency operations within Wyoming borders, including those addressed through Wyoming federal government relations
- Internal governance of the 23 federally recognized tribal nations or the Wind River Reservation, which operate under tribal sovereignty and federal Indian law
- Municipal code provisions adopted under home rule authority, though those provisions must remain consistent with Article 13

A comparison of constitutional versus statutory authority clarifies the boundary: constitutional provisions require voter ratification to modify; statutes require only legislative action. When a Wyoming executive branch agency issues a rule that conflicts with a constitutional provision, the rule is void regardless of its statutory authorization. When the conflict is with a statute only, ordinary administrative law remedies apply. This hierarchy is the foundational operating principle for any practitioner working within Wyoming state government.
