How a Bill Becomes Law in Wyoming

The Bill Lifecycle

Every bill follows these steps. Not all bills make it to the end; most die in committee or fail on the floor.

1. 1

   Drafting & Introduction

   A legislator works with the Legislative Service Office (LSO) to draft the bill text. The bill receives a number (House Bills start with HB, Senate Files with SF) and its title is read aloud for the first time (first reading).

2. 2

   Committee Referral

   The presiding officer assigns the bill to a standing committee organized by policy area (e.g., House Revenue, Senate Judiciary). The committee holds hearings where the public can testify.

3. 3

   Committee Action

   The committee votes on whether to recommend the bill to the full chamber. Options include "Do Pass" (recommend as-is), "Amend and Do Pass" (recommend with changes), or no action, which effectively kills the bill.

4. 4

   Floor Debate & Second Reading

   The bill is placed on the general file (the chamber's agenda) for floor debate. In Committee of the Whole, all members debate the bill. On second reading, any legislator may offer amendments. This is where most changes happen.

5. 5

   Third Reading & Final Vote

   The final passage vote in the chamber of origin. No amendments are allowed at third reading. A roll call vote is taken, recording each legislator's position (Yea, Nay, Absent, Excused, Conflicts).

6. 6

   Crossover to the Other Chamber

   After passing one chamber, the bill is sent to the other (House to Senate, or Senate to House). It goes through the same process: committee referral, hearings, floor debate, and three readings.

7. 7

   Conference Committee

   If the two chambers pass different versions of the bill, a Joint Conference Committee (JCC) is appointed to reconcile the differences. Both chambers must adopt the conference report.

8. 8

   Engrossment & Enrollment

   The engrossed version incorporates all adopted amendments. The enrolled version is the final clean text, signed by the Speaker of the House and President of the Senate.

9. 9

   Governor's Action

   The Governor may sign the bill into law, veto it, or allow it to become law without a signature. For appropriations bills, the Governor may also exercise a line-item veto on specific spending items.

10. 10

    Effective Date

    Most laws take effect on July 1 following the session. Some bills include an "immediate effective date" clause and take effect as soon as the Governor signs.

Why Wyoming Is Different

Wyoming’s legislature works differently from Congress and from most other states.

Glossary

Terms you’ll encounter on bill detail pages. Tap the ⓘ icons throughout the site for quick definitions; they link back here for the full explanation.

Absent (Vote)

When a legislator is absent for a roll call vote, it means they were not on the chamber floor when the vote was taken. Absences can occur for many reasons: scheduling conflicts with committee meetings, illness, personal obligations, or travel. An absence should not be interpreted as support or opposition to the measure. In Wyoming's short sessions, legislators sometimes miss votes because multiple proceedings happen simultaneously.

Amendment

Amendments are proposed changes to a bill's text. They can be offered in committee (standing committee amendments) or on the floor during second reading (floor amendments). Each amendment receives its own number (e.g., HB0001H2005) and may be voted on by roll call. An amendment can be adopted, failed, withdrawn, or divided (split into parts). The budget bill (HB0001) often has dozens of amendments. Amendment votes are separate from the vote on the bill itself.

Appropriations Bill

Appropriations bills direct how the state spends money. The main budget bill (typically HB0001) funds all state agencies and is the most-amended bill each session. In budget sessions (even-numbered years), appropriations bills are the primary focus. The Governor may exercise a line-item veto on specific spending items in appropriations bills, unlike other legislation where the veto applies to the entire bill.

Bill Sponsor

Every bill in Wyoming must have a primary sponsor from the chamber where it is introduced. The sponsor is the legislator who formally files the bill, presents it in committee, and advocates for it on the floor. Sponsoring a bill does not necessarily mean the legislator wrote it; bills may originate from constituents, interest groups, or executive agencies. Some bills also list co-sponsors from the House and Senate, shown separately on the bill detail page. Committee-sponsored bills (e.g., Joint Appropriations) list the committee rather than an individual legislator.

Budget Session

Wyoming holds budget sessions in even-numbered years (2024, 2026, etc.). These sessions are limited to 20 working days and focus primarily on appropriations (the state budget) and revenue bills. The legislature may also consider other bills if two-thirds of both chambers vote to introduce them. Budget sessions are shorter and more focused than general sessions.

Caucus Chairman

The caucus chairman organizes and presides over closed-door meetings of the party's members. These meetings are where legislators discuss upcoming bills, set priorities for the session, and work out internal disagreements before taking debates to the floor. The caucus chairman helps maintain party cohesion without the formal procedural authority of the floor leader or presiding officer.

Citizen Legislature

Wyoming has a part-time citizen legislature — one of the few remaining in the United States. The 93 members (31 senators, 62 representatives) are paid $150 per day plus a per diem during sessions, and most hold other jobs year-round. This means legislators stay closely connected to their communities, but also have limited time and staff compared to full-time legislatures. The legislature meets for just 20–40 working days per year.

Official source ↗

Committee Chair

Each committee has a chair (or co-chairs for joint committees) who controls which bills get heard, sets meeting agendas, recognizes speakers during testimony, and calls votes. The chair has significant influence over which bills advance from committee. In Wyoming's joint interim committees, there are two co-chairs — one from the House and one from the Senate.

Official source ↗

Committee of the Whole

Committee of the Whole (COW) is a procedural step where the entire chamber sits as one large committee to debate a bill. This allows more flexible rules for discussion than formal floor debate. After the COW passes a bill, it advances to second reading. If the COW does not consider a bill (shown as 'Did not consider for COW'), the bill may still advance through other procedural paths, but this often signals trouble.

Committee Referral

After introduction, the presiding officer assigns the bill to a standing committee (e.g., House Revenue, Senate Judiciary). The committee holds hearings where the public can testify, reviews the bill text, and may propose amendments. Most bills live or die in committee — if the committee takes no action, the bill typically does not advance.

Official source ↗

Committee Vote (Advisory)

When a standing committee votes on a bill during session, the result is a recommendation to the full House or Senate. A ‘Do Pass’ recommendation sends the bill to the floor with committee support, while ‘Do Not Pass’ signals the committee opposes it. However, the full chamber still makes the final decision — a bill can pass the floor despite a negative committee recommendation, or die on the floor despite a positive one. Committee votes use ‘Recommended’/‘Not Recommended’ labels to distinguish them from final floor votes.

Official source ↗

Concurrence

When the second chamber amends a bill that already passed the first chamber, it sends the amended version back. The original chamber then votes on 'concurrence' — whether to accept the other chamber's changes. If concurrence passes, the bill proceeds to enrollment. If concurrence fails, the bill may go to a conference committee to reconcile differences.

Conference Committee

When the House and Senate pass different versions of the same bill and cannot agree through the concurrence process, a Joint Conference Committee (JCC) is appointed. Each chamber's presiding officer selects three members to serve, typically including legislators who worked on the bill in committee. The six-member JCC meets to negotiate a compromise version that both sides can accept. The resulting conference committee report must then be adopted by a majority vote in both chambers — no further amendments are allowed; each chamber votes the report up or down. If either chamber rejects the report, the JCC may try again or the bill may die. Conference committees are relatively uncommon in Wyoming's short sessions but are critical for high-profile bills, especially the budget, where the House and Senate versions often differ significantly.

Official source ↗

Conflicts (Vote)

Wyoming law requires legislators to disclose conflicts of interest that could influence their vote. When a legislator declares a conflict, they formally recuse themselves from voting on that specific measure. The conflict is recorded in the official journal. This is a legal obligation, not an expression of support or opposition. In a citizen legislature where members hold outside jobs, conflicts arise naturally when legislation affects a member's profession, business, or financial interests.

Council or Commission

Councils and commissions are boards, advisory panels, and interstate compacts that include legislative members alongside executive-branch or citizen appointees. Unlike joint interim committees, they generally do not draft legislation or hold bill hearings. Examples include the State Building Commission, the Energy Council, and the Interstate Compact for Juveniles. Wyoming legislators serve on these bodies as liaisons or representatives.

Official source ↗

Crossover

Once a bill passes all three readings in its chamber of origin (House or Senate), it 'crosses over' to the other chamber. There, it goes through the same process: committee referral, committee review, and three readings. If the second chamber amends the bill, it must return to the original chamber for concurrence on the changes.

CSG Committee

The Council of State Governments (CSG) is a nonpartisan organization that brings together state officials to share best practices. CSG West is the regional affiliate covering western states. Wyoming legislators appointed to CSG committees participate in cross-state policy discussions on topics like energy, agriculture, and education. These are external assignments, not Wyoming legislative committees.

Official source ↗

Effective Date

Most Wyoming laws take effect on July 1 following the session in which they were passed. However, some bills include an 'immediate effective date' clause, meaning they take effect as soon as the Governor signs them. The effective date is noted in the bill's action history.

Engrossment

After a bill passes with amendments, the 'engrossed' version is prepared — this is the bill text with all adopted amendments incorporated. The engrossed version replaces the original introduced text and becomes the working version for the other chamber. When you see an 'Engrossed (PDF)' link, that document shows the bill as amended.

Enrollment

After a bill passes both chambers in identical form, the 'enrolled' version is prepared — a clean final text signed by the Speaker of the House and President of the Senate. This is the version sent to the Governor for action. Enrolled acts are numbered sequentially (e.g., HEA No. 0042 for House Enrolled Act, SEA for Senate). When you see an 'Enrolled Act (PDF)' link, that is the final law as passed.

Excused (Vote)

An excused legislator has been formally released from voting by the chamber, usually by a motion or announcement from leadership. Unlike an absence, being excused is an official status recorded in the journal. Legislators may request to be excused for medical reasons, family emergencies, or other obligations. Being excused is procedurally neutral and should not be interpreted as a position on the bill.

Fiscal Note

A fiscal note is prepared by the Legislative Service Office (LSO) and estimates the financial impact of a bill on state and local government. It covers potential costs, revenue changes, and implementation requirements. Fiscal notes are advisory — they inform legislators' decisions but do not determine whether a bill passes. When available, the fiscal note is linked as a PDF on the bill detail page.

Floor Leader

Each party in each chamber elects a floor leader. The majority floor leader works closely with the presiding officer to schedule bills for debate and ensure the party's priorities advance. The minority floor leader coordinates the opposition's strategy, offers alternatives, and represents the minority caucus in procedural negotiations. Floor leaders are the primary spokespersons for their parties on the chamber floor.

General Session

Wyoming holds general sessions in odd-numbered years (2025, 2027, etc.). These sessions are limited to 40 working days and have a broader scope — any type of legislation may be introduced. General sessions typically see more bills (300–500) than budget sessions (200–300). Bills not passed by the end of a session are dead and must be reintroduced in a future session.

Governor's Action

After enrollment, the bill goes to the Governor. The Governor has three options: sign the bill into law, veto it (rejecting it), or allow it to become law without a signature by taking no action within the required timeframe. For appropriations bills (like the budget), the Governor may also exercise a line-item veto — signing the overall bill but vetoing specific spending items. The legislature can override a veto with a two-thirds vote in both chambers.

Interim Budget

Between sessions, joint interim committees receive a budget from Management Council to fund their study activities. This covers travel expenses for hearings held around the state, meeting costs, contracted research, and staff support. The budget amount varies by committee workload and the number of study topics assigned. Not all committees receive interim budgets — standing committees during session and external assignments (CSG, NCSL) do not have separate allocations.

Official source ↗

Introduction & First Reading

Every bill begins when a legislator files it with the chamber clerk. The bill receives a number (e.g., HB0042 for a House Bill, SF0015 for a Senate File) and its title is read aloud on the floor — this counts as the first of three constitutionally required readings. The bill is then referred to a standing committee for review.

Official source ↗

Joint Interim Committee

Between legislative sessions, Wyoming's standing committees in each chamber merge to form joint interim committees. These bipartisan committees study topics assigned by Management Council, hold public hearings around the state, and may draft legislation for the next session. Each joint committee has two co-chairs — one from the House and one from the Senate. There are 12 numbered joint committees corresponding to the standing committees (e.g., Joint Judiciary, Joint Appropriations).

Official source ↗

Laid Back

When a bill is 'laid back,' it means the chamber has postponed further action to a later date. This can happen at any reading stage. A bill may be laid back to allow more time for negotiation, to wait for related bills, or for other strategic reasons. A bill laid back indefinitely ('postponed indefinitely') is effectively dead for the session.

Legislative District

Wyoming's legislature is divided into 62 House districts and 31 Senate districts, each represented by one legislator. House districts nest within Senate districts, so every Senate district contains roughly two House districts. Boundaries are redrawn every ten years following the U.S. Census to maintain roughly equal population across districts. District numbers are geographic identifiers assigned during redistricting and do not imply rank or seniority.

LSO Digest

The Legislative Service Office (LSO) prepares a digest for each bill — a plain-language summary describing what the bill does in non-legal terms. The LSO is a nonpartisan staff agency that serves the legislature. Their digests are the most accessible way to understand a bill's purpose without reading the full legal text. Digests are available as PDFs linked from the bill detail page.

Official source ↗

Mirror Bill

Sometimes identical bills are introduced in both the House and Senate at the same time — one is the 'mirror' of the other (e.g., HB0001 and SF0001 for the budget). Typically only one advances while the other is noted as 'See Mirror Bill.' This is a procedural strategy, often used for the state budget.

NCSL Committee

The National Conference of State Legislatures (NCSL) is a bipartisan organization serving state legislators and staff. Wyoming legislators appointed to NCSL committees work with counterparts from other states on policy areas like budgets, health, education, and elections. These are external assignments, not Wyoming legislative committees.

Presiding Officer (Speaker / President)

In the House, the presiding officer is the Speaker of the House; in the Senate, it is the President of the Senate. Wyoming's Senate President is elected by senators, unlike Congress where the Vice President presides. The presiding officer decides which bills reach the floor and in what order, assigns bills to standing committees, appoints members to conference committees, and rules on procedural questions. This makes the role one of the most influential in the legislature.

Pro Tempore / Vice President

The House Speaker Pro Tempore and Senate Vice President serve as stand-ins for the presiding officer. When the Speaker or President is absent, the pro tempore or vice president takes the chair and exercises full presiding authority, including ruling on procedural questions. If the presiding officer's seat is permanently vacated, they assume the role until a new election is held.

Roll Call Vote

A roll call vote records how each individual legislator voted — Yea (in favor), Nay (against), Absent (not present), Excused (officially excused from voting), or Conflict (recused due to a conflict of interest). Vote tallies are shown as five numbers (e.g., '47-14-1-0-0') representing Yea-Nay-Absent-Excused-Conflicts. Roll call votes happen on third reading (final passage), amendments, and some procedural motions. Not every legislative action involves a roll call — voice votes and unanimous consent are also used.

Second Reading

Second reading is the primary opportunity for the full chamber to debate the bill and offer amendments. Any legislator may propose amendments, which are voted on individually. This is typically where the most substantive changes to a bill occur. After second reading, the bill may be 'laid back' (postponed) for further consideration, or it advances to third reading.

Select Committee

Select committees are created by the Legislature to study specific issues that don't fall neatly within a standing committee's jurisdiction, or that require focused attention. They may be established by statute or by Management Council, and typically have a defined scope and duration. Examples include the Select Water Committee and the Select Committee on Tribal Relations.

Official source ↗

Standing Committee

Standing committees are permanent groups of legislators organized by policy area (e.g., Judiciary, Appropriations, Education). They review bills, hold public hearings, take testimony, and vote on whether to recommend a bill to the full chamber. The committee may recommend the bill as-is ('Do Pass'), with amendments ('Amend and Do Pass'), or may let it die without action. Each chamber has its own set of standing committees.

Official source ↗

Third Reading

Third reading is the final vote on a bill in its chamber. No amendments are allowed at this stage — the bill is voted on as-is. A roll call vote is taken, recording each legislator's position (Yea, Nay, Absent, Excused). A simple majority is required for passage. The vote tallies shown (e.g., '47-14-1-0-0') represent Yea-Nay-Absent-Excused-Conflicts.

Veto

A veto is the Governor's rejection of a bill passed by the legislature. When a bill is vetoed, it does not become law unless the legislature overrides the veto with a two-thirds supermajority vote in both chambers. A line-item veto applies only to appropriations bills — the Governor signs the bill overall but rejects specific spending items.

Whip

The whip is the floor leader's chief deputy. Before important votes, the whip surveys party members to gauge support or opposition and reports the count back to leadership. They also work to ensure members are present on the floor for close votes. Not every caucus uses a whip; for example, the Wyoming Senate Republican caucus does not currently have one, with those duties handled directly by the majority floor leader.
