The Missouri legislature is one of 16 state legislatures with term limits. Voters enacted the Missouri Term Limits Act in 1992. That initiative said that Missouri senators are subject to term limits of no more than two four-year terms, or a total of eight years.[16]
The first year that the 1992 term limits impacted the ability of incumbents to run for office was 2002.
If there is a vacancy in the Missouri General Assembly, the governor of Missouri must call for a special election without delay. The election mandate is sent to the county or counties in the legislative district.[17]

The state of Missouri has 197 legislative districts. Each district elects one representative. The state Senate has 34 districts and the state House has 163 districts.

In Missouri, congressional district boundaries are drawn by the state legislature. These lines are subject to veto by the governor.[18]
In 2018, the voters passed a citizens’ initiative called Amendment 1 that reshaped the redistricting process; in 2020, the voters narrowly passed a legislatively referred initiative called Amendment 3 that reshaped the process again.
Two distinct politician commissions are ultimately responsible for state legislative redistricting, one for the Missouri State Senate and another for the Missouri House of Representatives. Membership on these commissions is determined as follows:[18]

Missouri’s congressional districts are drawn by the state legislature, as a regular statute, subject to gubernatorial veto. The state legislative lines are drawn by two separate politician commissions — one for state Senate districts, one for state House districts. For each commission, each major party’s congressional district committee nominates 2 members per congressional district, and the state committee nominates 5 members; the Governor chooses 1 per district per party and two per party from the statewide lists, for a total commission of 20.[6] |

Missouri completed its legislative redistricting on March 15, 2022, when the state’s Judicial Redistricting Commission filed new state Senate district boundaries with the secretary of state.[19] Missouri was the 43rd state to complete legislative redistricting. The House Independent Bipartisan Citizens Commission unanimously approved the state House’s district boundaries on Jan. 21.[20] These maps took effect for Missouri’s 2022 legislative elections.
The Senate Independent Bipartisan Citizens Commission failed to submit proposed maps to the secretary of state's office by the December 23, 2021, deadline. Therefore, responsibility for developing Senate district boundaries was assumed by the Missouri Judicial Commission for Redistricting.[21] The judicial commission released their final plan and sent it to the secretary of state's office on March 15, 2022. The commission’s chair, Missouri Appeals Court Justice Cynthia Lynette Martin, said in a press release, "The Judicial Redistricting Commission’s work has been thorough and labor intensive, and was purposefully undertaken with the goal to file a constitutionally compliant plan and map well in advance of the commission’s constitutional deadline to avoid disenfranchising voters given the candidate filing deadline and the deadline for preparing ballots."[22] Scott Faughn of The Missouri Times wrote that "The biggest difference in this map and that previous map is that it shifts the weight of some of the districts from rural weighted districts to evenly split districts and even enhances the suburban influence inside several republican seats." He added, "the new map produces 7 solid democratic districts, and 3 likely democratic districts. On the republican side the new map produces 18 solid republican districts, and 3 more likely republican districts," with two competitive districts when the current incumbents no longer seek office.[23]
The House Independent Bipartisan Citizens Commission unanimously approved new state House district boundaries on January 19, 2022. Fourteen of the commission's 20 members were required to approve the plan. If the commission was unable to agree on a redistricting plan by January 23, 2022, authority over the process would have transferred to the Missouri Judicial Commission for Redistricting.[24] In a press release issued after the map was finalized, commission chair Jerry Hunter said, "I want to personally thank all of the commissioners for the hard work that was put in by the commissioners and, obviously, as all of you know, the supporting individuals that have been instrumental to helping get this map done on both sides – on both the Democratic and Republican sides."[25] Rudi Keller of the Missouri Independent wrote, "Of the 163 districts..., there are 38 where Democrats should have the advantage, 97 where Republicans are dominant and 28 districts with past election results showing less than a 10% advantage for either party."[24]
Missouri received its local census data on February 24, 2011. The state's population increased by seven percent, with most growth coming in the southern half of the state. The five most populous cities showed mixed outcomes: Kansas City's population grew by 4.1 percent, St. Louis' population decreased by 8.3 percent, Springfield's population grew by 5.2 percent, Independence's population grew by 3.1 percent, and Columbia's population grew by 28.4 percent.[26]
The House and Senate bi-partisan redistricting commissions failed to agree on a new plan for Missouri's legislative districts, and the deadline for selecting a plan passed on August 18, 2011, resulting in a special court panel taking over.[27] On October 13, 2011, the judicial panel tasked with redrawing Missouri’s legislative districts heard public testimony, and the panel finalized the state's new legislative redistricting maps on November 30, 2011.[28][29] The Missouri Supreme Court overturned the state's Senate redistricting maps on January 17, 2012, and on January 31, 2012, Governor Jay Nixon (D) appointed a new commission for the sake of redrawing the Senate districts.[30][31] The commission approved a new plan on February 23, 2012, which was met with opposition and had a lawsuit filed against it. After hearing testimony and tweaking the map, the commission approved the map again on March 12, and the lawsuit was dropped.[32]

In 2012, the legislature was in session from January 4 through May 30.[48][49] Major issues in 2012[edit]The budget was the main focus of the session, as the state faced a $500 million spending gap in January. The agenda at the start of the session also included economic development, Workers Compensation reforms, and overhauling public school funding.[50] Those items joined health care exchanges, birth control, charter schools, and sentencing guidelines for crack cocaine crimes as points of contention and accomplishment over the course of the session.[51] 2011[edit]In 2011, the legislature was in regular session from January 5 through May 30.[52] Governor Jay Nixon (D) called for a special legislative session for September 6, however, the session was called off when Republicans hesitated on a push to overhaul state tax credits and authorize several new incentive programs, including one for a China freight hub in St. Louis. Assembly members were sent home so that they might read the revised 219-page measure over the weekend. According to Senate President Pro Tem Robert Mayer, the "important" bill "needs the attention of every member of this body."[53] Session highlights[edit]Budget cuts[edit]Lawmakers passed a $23.3 billion budget for the 2012 fiscal year in May 2011, representing a $500 million spending cut compared with the previous year. Governor Jay Nixon (D) cut an additional $172 million through withholds and $30,000 using his line-item veto before signing off on the budget plan. Withholds are an exercise of the governor's veto authority, but can be restored to the budget if revenues become available. Education and culture were the big losers in the budget plan, with state universities and community colleges absorbing an average 7 percent cut in state support, and funding completely cut for state arts, public TV and radio programs. The legislature itself saw its budget cut by 4.6 percent, while spending on the Missouri Housing Development Corporation housing assistance program was halved. Still, some programs did see substantial funding increases, including school bus transportation (21 percent), two state higher education scholarships (7 percent), and aid to service providers catering to people with developmental disabilities (2 percent). A new pharmacy partnership between Missouri State University and UMKC was also instituted, receiving $2 million in funding.[54] 2010[edit]In 2010, the legislature was in session from January 6th to May 14th.[55][56] |
The Tenth Amendment of the U.S. Constitution declares that any power not already given to the federal government is reserved to the states and the people.[57] State governments across the country use this authority to hold legislative sessions where a state's elected representatives meet for a period of time to draft and vote on legislation and set state policies on issues such as taxation, education, and government spending. The different types of legislation passed by a legislature may include resolutions, legislatively referred constitutional amendments, and bills that become law.
Article III of the Missouri Constitution establishes when the Missouri General Assembly, of which the Senate is a part is to meet. Section 20 of Article III states that the General Assembly shall convene its regular session on the first Wednesday after the first Monday in January of each year. Section 20 requires the General Assembly to adjourn its regular session by May 30th.
Section 20 of Article III also allows for a special session of the General Assembly to be convened by a joint proclamation of three-fourths of the members of both houses.
Every state legislature throughout the country features its own internal procedures that it uses to govern itself and how it interacts with other parts of state government. Ballotpedia's coverage of internal state legislative procedures includes veto overrides, the role of the legislature in the state budget, term limits, procedures for filling membership vacancies, and redistricting.
State legislatures can override governors' vetoes. Depending on the state, this can be done during the regular legislative session, in a special session following the adjournment of the regular session, or during the next legislative session. The rules for legislative overrides of gubernatorial vetoes in Missouri are listed below.
How many legislators are required to vote for an override? Two-thirds of members in both chambers.
| Two-thirds of members in both chambers must vote to override a veto, which is 109 of the 163 members in the Missouri House of Representatives and 23 of the 34 members in the Missouri State Senate. Missouri is one of 36 states that requires a two-thirds vote from both of its legislative chambers to override a veto. |
How can vetoes be overridden after the legislature has adjourned?
| According to Article III, Section 32 of the Missouri Constitution, the legislature shall automatically convene in a special veto session in September to consider overrides for any bill the governor vetoed less than six days before adjournment or after adjournment. |
Authority: Article III, Section 32 of the Missouri Constitution.
| "Every bill presented to the governor and returned with his objections shall stand as reconsidered in the house to which it is returned. If the governor returns any bill with his objections on or after the fifth day before the last day upon which a session of the general assembly may consider bills, the general assembly shall automatically reconvene on the first Wednesday following the second Monday in September for a period not to exceed ten calendar days for the sole purpose of considering bills returned by the governor. The objections of the governor shall be entered upon the journal and the house shall proceed to consider the question pending, which shall be in this form: “Shall the bill pass, the objections of the governor thereto notwithstanding? The vote upon this question shall be taken by yeas and nays and if two-thirds of the elected members of the house vote in the affirmative the presiding officer of that house shall certify that fact on the roll, attesting the same by his signature, and send the bill with the objections of the governor to the other house, in which like proceedings shall be had in relation thereto. The bill thus certified shall be deposited in the office of the secretary of state as an authentic act and shall become a law." |
| Missouri on |
The state operates on an annual budget cycle. The sequence of key events in the budget process is as follows:[58]
Missouri is one of 44 states in which the governor has line item veto authority.[58][59]
The governor is legally required to submit a balanced budget. The legislature is not required to pass a balanced budget, but the governor is required to sign one.[58]
Every state legislature and state legislative chamber in the country contains several legislative committees. These committees are responsible for studying, amending, and voting on legislation before it reaches the floor of a chamber for a full vote. The different types of committees include standing committees, select or special, and joint.
Ballotpedia covers standing and joint committees. The Missouri State Senate has 22 standing committees:
In every state but Delaware, voter approval is required to enact a constitutional amendment. In each state, the legislature has a process for referring constitutional amendments before voters. In 18 states, initiated constitutional amendments can be put on the ballot through a signature petition drive. There are also many other types of statewide measures.
The methods in which the Missouri Constitution can be amended:
The Missouri Constitution can be amended via three different paths—a citizen-initiated process, a legislative process, and a state constitutional convention.
An initiated constitutional amendment is a citizen-initiated ballot measure that amends a state's constitution. Eighteen (18) states allow citizens to initiate constitutional amendments.
In Missouri, the number of signatures required for an initiated constitutional amendment is based on the number of votes cast for governor in the state's most recent gubernatorial election. In two-thirds of Missouri's congressional districts, proponents must collect signatures equal to 8% of the gubernatorial vote for initiated constitutional amendments. A simple majority vote is required for voter approval.
A simple majority vote is required during one legislative session for the Missouri General Assembly to place a constitutional amendment on the ballot. That amounts to a minimum of 82 votes in the Missouri House of Representatives and 18 votes in the Missouri State Senate, assuming no vacancies. Amendments do not require the governor's signature to be referred to the ballot.
According to Section 3a of Article XII of the Missouri Constitution, a question about whether to hold a state constitutional convention is to automatically appear on the state's ballot every 20 years starting in 1942. Missouri is one of 14 states that provides for an automatic constitutional convention question.
