Constitutional definition

The Colorado Constitution establishes a system of government based on the separation of powers doctrine with power divided among the executive (government), executive, legislature, legislative and judiciary, judicial branches of government. Article V vests the legislative power of the state in the General Assembly, while reserving to the people the power to propose, approve, and reject both laws and amendments to the state Constitution by List of Colorado ballot measures, initiatives or referendums.Article V, Section 1 of the Colorado Constitution

The General Assembly is bicameral, composed of the Colorado House of Representatives and the Colorado Senate. The House has 65 members and the Senate 35. Members of the House are elected to two-year terms, and members of the Senate are elected to four-year terms. General legislative elections are held on the first Tuesday after the first Monday in November in each even-numbered year. The entire House is elected in each general election. Senators are elected in two classes such that, as nearly as possible, one-half of the senators are elected in each general election. House members are term limit, limited to four consecutive terms in office, and state senators are limited to two consecutive terms. However, term-limited former members of both houses can run again after a four-year break. The vast majority of members of the General Assembly who are ultimately elected (in excess of 90% of members ultimately elected in all recent sessions) are nominated through a major political party caucus process that places candidates on a primary ballot for the position sought in their political party, which generally requires 30% support from delegates to the relevant nominating body of the political party. It is also possible for individuals who have been registered to vote and affiliated with the political party in question for at least a year to gain access to a partisan primary ballot by petition. Minor party candidates can gain access to the general election ballot through a minor party caucus process. Unaffiliated candidates can gain access to the general election ballot by petition. Vacancies in legislative offices are generally filled by political party vacancy committees, rather than by-elections. Vacancy appointees who fill the first half of a state senators term must stand for election at the next even year November election for the remainder of the state senate term for the seat to which the state senator was appointed. The state auditor is appointed by the General Assembly, as are many members of independent boards and commissions. Currently, the Colorado General Assembly is controlled by the Democratic Party. Democrats also hold the Governor's office. The Colorado General Assembly was the first state legislature to welcome women as elected members, with Clara Cressingham, Carrie C. Holly and Frances S. Klock all being elected to the State House of Representatives in 1894 and Helen Ring Robinson, Helen Robinson being elected to the State Senate in 1912 (the second state upper house in the country to welcome women as members).

Procedure and powers

With the notable exceptions listed below, the Colorado General Assembly operates in a manner quite similar to the United States Congress.How a Bill Becomes Colorado Law
, Office of Legislative Legal Services, October 2001 (accessed April 29, 2013)
Regular sessions are held annually and begin no later than the second Wednesday in January. Regular sessions last no more than 120 days. Special sessions may be called at any time by the governor of Colorado, Governor or upon written request of two-thirds of the members of each house, but are infrequent. Some committees of the General Assembly work between sessions and have limited power to take action without General Assembly approval between legislative sessions. Joint procedural rules of the two chambers require most legislation to be introduced very early in the legislative session each year, and to meet strict deadlines for completion of each step of the legislative process. Joint procedural rules also limit each legislator to introducing five bills per year, subject to certain exceptions for non-binding resolutions, uniform acts, interim committee bills and appropriations bills. Most members of the General Assembly decide which bills they will introduce during the legislative session (or most of them) prior to its commencement, limiting the ability of members to introduce new bills at constituent request once the legislative session has begun. Image:ColoradoStateCapitolSenateChamber gobeirne.jpg, 350px, Senate Chamber Most bills adopted by the General Assembly include a "safety clause" (i.e. a legislative declaration that the bill concerns an urgent matter) and take effect on July 1 following the legislative session unless otherwise provided. Some bills are enacted without a "safety clause" which makes it possible to petition to subject those bills to a referendum before they take effect, and have an effective date in August following the legislative session unless otherwise provided. Colorado's legislature does not have an analog to the filibuster in the United States Senate requiring a supermajority for approval of any matter. The Lieutenant Governor does not have the power to preside or break tie votes in either house of the General Assembly. All new executive branch rules are reviewed annually by the legislature and the legislature routinely invalidates some of them each year. The General Assembly does not have a role in the appointment or retention of state judges, although it must authorize the creation of each judgeship. Many state agencies and programs are subject to "sunset review" and are automatically abolished if the General Assembly does not reauthorize them.

The state budget process

The governor submits a proposed budget to the Joint Budget Committee each year in advance of the year's legislative session. Colorado's fiscal year is from July 1 to June 30. All bills introduced in the General Assembly are evaluated by the non-partisan state legislative services body for their fiscal impact and must be provided for in appropriations legislation if there is a fiscal impact. A state budget, called the "Long Bill" is prepared each year by the Joint Budget Committee of the General Assembly. Unlike many legislative initiatives, the Long Bill is neither an acronym nor named after an individual with significant influence. The Long Bill is simply a lengthy bill that contains many appropriations. The House and the Senate alternate the job of introducing the long bill and making a first committee review of it. Colorado's state legislature is required to obtain voter approval in order to incur significant debt, to raise taxes, or to increase state constitutional spending limitations. It is also required to comply with a state constitutional spending mandate for K-12 education. The Governor has line item veto power over appropriations.

Legislative staff

The Colorado General Assembly is staffed by approximately 230-year-round staff and 115 session-only staff. Staffing levels and expenditures have decreased since 2003. Similarly to Congressional staffers, legislative staff in Colorado fall into five broad categories: Legislative staff in Colorado#Member staff, member staff, Legislative staff in Colorado#Administrative staff, administrative staff, Legislative staff in Colorado#Committee staff, committee staff, Legislative staff in Colorado#Communications and leadership staff, communications and leadership staff, and Legislative staff in Colorado#Legal service staff, legal service staff. With the exception of those working in communications and leadership, employees of the General Assembly are non-partisan staffers.

Current makeup

Based on the 2010 census, each House member represents about 77,372 Electoral district, constituents and each Senator 143,691. The 2018 Colorado elections resulted in Democrats extending their control in the House (41 Democrats; 24 Republicans) and capturing the Senate majority. The current Senate makeup is 20 Democrats and 15 Republicans. There are 65 House Members and 35 Senate Members making up the 100 seats in Colorado General Assembly.
