TheIllinois General Assembly is thelegislature of theU.S. state ofIllinois. It hastwo chambers, theIllinois House of Representatives and theIllinois Senate. The General Assembly was created by the firststate constitution adopted in 1818. As of 2025[update], the General Assembly is the 104th. The term of an assembly lasts two years.
Under the Illinois Constitution, since 1983 the Senate has had 59 members and the House has had 118 members. In both chambers, all members are elected fromsingle-member districts and districts are drawn to represent generally equal populations and redrawn every ten years based on census returns. Each Senate district is divided into two adjacent House districts.
The General Assembly meets in theIllinois State Capitol inSpringfield. Itssession laws are generally adopted by majority vote in both houses, and upon gaining the assent of theGovernor of Illinois. They are published in the officialLaws of Illinois.[1][2]
Twopresidents of the United States,Abraham Lincoln andBarack Obama, began their political careers in the Illinois General Assembly, in the Illinois House of Representatives and Illinois Senate, respectively.
The Illinois General Assembly was created by the firststate constitution adopted in 1818. Initially, the state did not have organized political parties, but the Democratic andWhig parties began to form in the 1830s.
Future U.S. PresidentAbraham Lincoln successfully campaigned as a member of the Whig Party to serve in the General Assembly in 1834.[3] He served four successive terms 1834–42 in theIllinois House of Representatives, supporting expanded suffrage and economic development. He later went to the presidency as part of then new Republican Party.[4]
In 1877,John W. E. Thomas was the first African American elected to the legislature.[5] In 1922,Lottie Holman O'Neill was elected to theIllinois House of Representatives, becoming the first woman to serve in the Illinois General Assembly.[6]
Future U.S. PresidentBarack Obama was elected to theIllinois Senate in 1996, serving there until 2004 when he was elected to theUnited States Senate.[7]
The size of the General Assembly has changed over time. Thefirst General Assembly, elected in 1818, consisted of 14 senators and 28 representatives.[8] Under the1818 and1848 Illinois Constitutions, the legislature could add and reapportion districts at any time, and by 1870 it had done so ten times.[9] Under the1870 Illinois Constitution, Illinois was divided into 51 legislative districts, each of which elected one senator and three representatives.[9] The representatives were elected bycumulative voting, in which each voter had three votes that could be distributed among one, two, or three candidates. Due to the unwillingness ofdownstate Illinois to cede power to the growing Chicago area, the district boundaries were not redrawn from 1901 to 1955.[10]
After voters approved theLegislative Apportionment Amendment in 1954, there were 58 Senate districts and 59 House districts, which did not necessarily coincide. This new arrangement was conceived as a "little federal" system: the Senate districts would be based onland area and would favor downstate, while the House districts would be based on population. House members continued to be elected by cumulative voting, three from each House district.[11] With the adoption of the1970 Illinois Constitution, the system of separate House and Senate districts was eliminated, and legislative districts were apportioned on aone person, one vote basis.[12] The state was divided into 59 legislative districts, each of which elected one senator and three representatives.
The cumulative voting system was abolished by theCutback Amendment in 1980. Since then, the House has been elected from 118 single-member districts, which are formed by dividing each of the 59 Senate districts in half.[13] Each senator is "associated" with two representatives.
Members of the House of Representatives are elected to a two-year term withoutterm limits.
Members of the Illinois Senate serve two four-year terms and one two-year term each decade. This ensures that Senate elections reflect changes made when the General Assembly is redistricted following eachUnited States Census. To prevent complete turnovers in membership (except after an intervening Census), not all Senators are elected simultaneously. The term cycles for the Senate are staggered, with the placement of the two-year term varying from one district to another. Each district's terms are defined as 2-4-4, 4-2-4, or 4-4-2. Like House members, Senators are elected without term limits.
The officers of the General Assembly are elected at the beginning of eacheven-numbered year. Representatives of the House elect from its membership aSpeaker and Speaker pro tempore, drawn from the majority party in the chamber. TheIllinois Secretary of State convenes and supervises the opening House session and leadership vote. State senators elect from the chamber aPresident of the Senate, convened and under the supervision of thegovernor. Since the adoption of the currentIllinois Constitution in 1970, theLieutenant Governor of Illinois does not serve in any legislative capacity as Senate President, and has had its office's powers transferred to other capacities. TheIllinois Auditor General is a legislative officer appointed by the General Assembly that reviews all state spending for legality.[14]
The General Assembly's first official working day is the second Wednesday of January each year. The Secretary of State presides over the House until it chooses aSpeaker and the governor presides over the Senate until it chooses aPresident.[15] Both chambers must also select a Minority Leader from among the members of the second most numerous party.
In order to serve as a member in either chamber of the General Assembly, a person must be a U.S. citizen, at least 21 years of age, and for the two years preceding their election or appointment a resident of the district which they represent.[15] In the general election following a redistricting, a candidate for any chamber of the General Assembly may be elected from any district which contains a part of the district in which they resided at the time of the redistricting and reelected if a resident of the new district they represents for 18 months prior to reelection.[15]
Members of the General Assembly may not hold other public offices or receive appointments by the governor, and their salaries may not be increased during their tenure.[15]
Seats in the General Assembly may become vacant due to a member resigning, dying, being expelled, or being appointed to another office. Under the Illinois Constitution, when a vacancy occurs, it must be filled by appointment within 30 days.[16] If a Senate seat becomes vacant more than 28 months before the next general election for that seat, an election is held at the next general election. The replacement member must be a member of the same party as the departing member.[16] The General Assembly has enacted a statute governing this process.[17] Under that statute, a replacement member is appointed by the party committee for that district, whose votes are weighted by the number of votes cast for that office in the area that each committee member represents.[17][18]
The appointment process was unsuccessfully challenged before theIllinois Supreme Court in 1988 as an unconstitutional grant of state power to political parties, but the challenge failed.[18]
The governor canveto bills passed by the General Assembly in four different ways: a full veto, an amendatory veto, and, for appropriations only, anitem veto and a reduction veto.[19] Theseveto powers are unusually broad among US state governors.[20] The line item veto was added to the Illinois Constitution in 1884.[21] The amendatory and reduction vetoes were new additions in the 1970 Constitution.[20]
The General Assembly can override full, amendatory and item vetoes by a three-fifths majority vote in both chambers.[19] It can override a reduction veto by a simple majority vote in both chambers.[22] If both chambers agree to the changes the governor suggests in an amendatory veto, these changes can be approved by a simple majority vote in both chambers. If the General Assembly approves an amended law in response to the governor's changes, the bill becomes law once the governor certifies that the suggested changes have been made.[22]
By statute, the General Assembly has the power to block regulations, including emergency regulations, proposed by state administrative agencies.[23] This power is currently exercised by theJoint Committee on Administrative Rules (JCAR). JCAR is made up of 12 members, with equal numbers from the House and Senate and equal numbers from each political party.[24] It can block proposed rules by a 3/5 vote.[25] The General Assembly can then reverse the block by ajoint resolution of both houses.[25]
JCAR was first established in 1978 and given only advisory powers.[26] The General assembly gave it the power to temporarily block or suspend administrative regulations for 180 days in 1980.[26] In September 2004, the General Assembly expanded this temporary suspension power into a permanent veto.[27] As the Illinois Constitution does not provide for alegislative veto, the constitutionality of this arrangement has been questioned.[28] Among the charges brought against GovernorRod Blagojevich in his 2009 impeachment trial was that he had not respected the legitimacy of JCAR blocking his rulemaking on healthcare in 2008.[28]
