The text

Constitution of the State of Colorado, Article V, Section 1. General assembly - initiative and referendumSection page →

(1) The legislative power of the state shall be vested in the general assembly consisting of a senate and house of representatives, both to be elected by the people, but the people reserve to themselves the power to propose laws and amendments to the constitution and to enact or reject the same at the polls independent of the general assembly and also reserve power at their own option to approve or reject at the polls any act or item, section, or part of any act of the general assembly.

(2) The first power hereby reserved by the people is the initiative, and signatures by registered electors in an amount equal to at least five percent of the total number of votes cast for all candidates for the office of secretary of state at the previous general election shall be required to propose any measure by petition, and every such petition shall include the full text of the measure so proposed. Initiative petitions for state legislation and amendments to the constitution, in such form as may be prescribed pursuant to law, shall be addressed to and filed with the secretary of state at least three months before the general election at which they are to be voted upon.

(2.5) In order to make it more difficult to amend this constitution, a petition for an initiated constitutional amendment shall be signed by registered electors who reside in each state senate district in Colorado in an amount equal to at least two percent of the total registered electors in the senate district provided that the total number of signatures of registered electors on the petition shall at least equal the number of signatures required by subsection (2) of this section. For purposes of this subsection (2.5), the number and boundaries of the senate districts and the number of registered electors in the senate districts shall be those in effect at the time the form of the petition has been approved for circulation as provided by law.

(3) The second power hereby reserved is the referendum, and it may be ordered, except as to laws necessary for the immediate preservation of the public peace, health, or safety, and appropriations for the support and maintenance of the departments of state and state institutions, against any act or item, section, or part of any act of the general assembly, either by a petition signed by registered electors in an amount equal to at least five percent of the total number of votes cast for all candidates for the office of the secretary of state at the previous general election or by the general assembly. Referendum petitions, in such form as may be prescribed pursuant to law, shall be addressed to and filed with the secretary of state not more than ninety days after the final adjournment of the session of the general assembly that passed the bill on which the referendum is demanded. The filing of a referendum petition against any item, section, or part of any act shall not delay the remainder of the act from becoming operative.

(4) (a) The veto power of the governor shall not extend to measures initiated by or referred to the people. All elections on measures initiated by or referred to the people of the state shall be held at the biennial regular general election, and all such measures shall become the law or a part of the constitution, when approved by a majority of the votes cast thereon or, if applicable the number of votes required pursuant to paragraph (b) of this subsection (4), and not otherwise, and shall take effect from and after the date of the official declaration of the vote thereon by proclamation of the governor, but not later than thirty days after the vote has been canvassed. This section shall not be construed to deprive the general assembly of the power to enact any measure.

(b) In order to make it more difficult to amend this constitution, an initiated constitutional amendment shall not become part of this constitution unless the amendment is approved by at least fifty-five percent of the votes cast thereon; except that this paragraph (b) shall not apply to an initiated constitutional amendment that is limited to repealing, in whole or in part, any provision of this constitution.

(5) The original draft of the text of proposed initiated constitutional amendments and initiated laws shall be submitted to the legislative research and drafting offices of the general assembly for review and comment. No later than two weeks after submission of the original draft, unless withdrawn by the proponents, the legislative research and drafting offices of the general assembly shall render their comments to the proponents of the proposed measure at a meeting open to the public, which shall be held only after full and timely notice to the public. Such meeting shall be held prior to the fixing of a ballot title. Neither the general assembly nor its committees or agencies shall have any power to require the amendment, modification, or other alteration of the text of any such proposed measure or to establish deadlines for the submission of the original draft of the text of any proposed measure.

(5.5) No measure shall be proposed by petition containing more than one subject, which shall be clearly expressed in its title; but if any subject shall be embraced in any measure which shall not be expressed in the title, such measure shall be void only as to so much thereof as shall not be so expressed. If a measure contains more than one subject, such that a ballot title cannot be fixed that clearly expresses a single subject, no title shall be set and the measure shall not be submitted to the people for adoption or rejection at the polls. In such circumstance, however, the measure may be revised and resubmitted for the fixing of a proper title without the necessity of review and comment on the revised measure in accordance with subsection (5) of this section, unless the revisions involve more than the elimination of provisions to achieve a single subject, or unless the official or officials responsible for the fixing of a title determine that the revisions are so substantial that such review and comment is in the public interest. The revision and resubmission of a measure in accordance with this subsection (5.5) shall not operate to alter or extend any filing deadline applicable to the measure.

(6) The petition shall consist of sheets having such general form printed or written at the top thereof as shall be designated or prescribed by the secretary of state; such petition shall be signed by registered electors in their own proper persons only, to which shall be attached the residence address of such person and the date of signing the same. To each of such petitions, which may consist of one or more sheets, shall be attached an affidavit of some registered elector that each signature thereon is the signature of the person whose name it purports to be and that, to the best of the knowledge and belief of the affiant, each of the persons signing said petition was, at the time of signing, a registered elector. Such petition so verified shall be prima facie evidence that the signatures thereon are genuine and true and that the persons signing the same are registered electors.

(7) The secretary of state shall submit all measures initiated by or referred to the people for adoption or rejection at the polls, in compliance with this section. In submitting the same and in all matters pertaining to the form of all petitions, the secretary of state and all other officers shall be guided by the general laws.

(7.3) Before any election at which the voters of the entire state will vote on any initiated or referred constitutional amendment or legislation, the nonpartisan research staff of the general assembly shall cause to be published the text and title of every such measure. Such publication shall be made at least one time in at least one legal publication of general circulation in each county of the state and shall be made at least fifteen days prior to the final date of voter registration for the election. The form and manner of publication shall be as prescribed by law and shall ensure a reasonable opportunity for the voters statewide to become informed about the text and title of each measure.

(7.5) (a) Before any election at which the voters of the entire state will vote on any initiated or referred constitutional amendment or legislation, the nonpartisan research staff of the general assembly shall prepare and make available to the public the following information in the form of a ballot information booklet:

(I) The text and title of each measure to be voted on; (II) A fair and impartial analysis of each measure, which shall include a summary and the major arguments both for and against the measure, and which may include any other information that would assist understanding the purpose and effect of the measure. Any person may file written comments for consideration by the research staff during the preparation of such analysis. (b) At least thirty days before the election, the research staff shall cause the ballot information booklet to be distributed to active registered voters statewide. (c) If any measure to be voted on by the voters of the entire state includes matters arising under section 20 of article X of this constitution, the ballot information booklet shall include the information and the titled notice required by section 20 (3)(b) of article X, and the mailing of such information pursuant to section 20 (3)(b) of article X is not required. (d) The general assembly shall provide sufficient appropriations for the preparation and distribution of the ballot information booklet pursuant to this subsection (7.5) at no charge to recipients. (8) The style of all laws adopted by the people through the initiative shall be, "Be it Enacted by the People of the State of Colorado". (9) The initiative and referendum powers reserved to the people by this section are hereby further reserved to the registered electors of every city, town, and municipality as to all local, special, and municipal legislation of every character in or for their respective municipalities. The manner of exercising said powers shall be prescribed by general laws; except that cities, towns, and municipalities may provide for the manner of exercising the initiative and referendum powers as to their municipal legislation. Not more than ten percent of the registered electors may be required to order the referendum, nor more than fifteen percent to propose any measure by the initiative in any city, town, or municipality. (10) This section of the constitution shall be in all respects self-executing; except that the form of the initiative or referendum petition may be prescribed pursuant to law.

Constitution of the State of Colorado, Article XIX, Section 2. Amendments to constitution - how adoptedSection page →

(1) (a) Any amendment or amendments to this constitution may be proposed in either house of the general assembly, and, if the same shall be voted for by two-thirds of all the members elected to each house, such proposed amendment or amendments, together with the ayes and noes of each house thereon, shall be entered in full on their respective journals. The proposed amendment or amendments shall be published with the laws of that session of the general assembly. At the next general election for members of the general assembly, the said amendment or amendments shall be submitted to the registered electors of the state for their approval or rejection, and such as are approved by a majority of those voting thereon or, if applicable the number of votes required pursuant to paragraph (b) of this subsection (1), shall become part of this constitution.

(b) In order to make it more difficult to amend this constitution, a constitutional amendment shall not become part of this constitution unless the amendment is approved by at least fifty-five percent of the votes cast thereon; except that this paragraph (b) shall not apply to a constitutional amendment that is limited to repealing, in whole or in part, any provision of this constitution.

(2) If more than one amendment be submitted at any general election, each of said amendments shall be voted upon separately and votes thereon cast shall be separately counted the same as though but one amendment was submitted; but each general assembly shall have no power to propose amendments to more than six articles of this constitution.

(3) No measure proposing an amendment or amendments to this constitution shall be submitted by the general assembly to the registered electors of the state containing more than one subject, which shall be clearly expressed in its title; but if any subject shall be embraced in any measure which shall not be expressed in the title, such measure shall be void only as to so much thereof as shall not be so expressed.

Constitution of the State of Colorado, Article XXI, Section 1. State officers may be recalledSection page →

Every elective public officer of the state of Colorado may be recalled from office at any time by the registered electors entitled to vote for a successor of such incumbent through the procedure and in the manner herein provided for, which procedure shall be known as the recall, and shall be in addition to and without excluding any other method of removal provided by law.

The procedure hereunder to effect the recall of an elective public officer shall be as follows:

A petition signed by registered electors entitled to vote for a successor of the incumbent sought to be recalled, equal in number to twenty-five percent of the entire vote cast at the last preceding election for all candidates for the position which the incumbent sought to be recalled occupies, demanding an election of the successor to the officer named in said petition, shall be filed in the office in which petitions for nominations to office held by the incumbent sought to be recalled are required to be filed; provided, if more than one person is required by law to be elected to fill the office of which the person sought to be recalled is an incumbent, then the said petition shall be signed by registered electors entitled to vote for a successor to the incumbent sought to be recalled equal in number to twenty-five percent of the entire vote cast at the last preceding general election for all candidates for the office, to which the incumbent sought to be recalled was elected as one of the officers thereof, said entire vote being divided by the number of all officers elected to such office, at the last preceding general election; and such petition shall contain a general statement, in not more than two hundred words, of the ground or grounds on which such recall is sought, which statement is intended for the information of the registered electors, and the registered electors shall be the sole and exclusive judges of the legality, reasonableness and sufficiency of such ground or grounds assigned for such recall, and said ground or grounds shall not be open to review.

Constitution of the State of Colorado, Article X, Section 20. The Taxpayer's Bill of RightsSection page →

(1) General provisions. This section takes effect December 31, 1992 or as stated. Its preferred interpretation shall reasonably restrain most the growth of government. All provisions are self-executing and severable and supersede conflicting state constitutional, state statutory, charter, or other state or local provisions. Other limits on district revenue, spending, and debt may be weakened only by future voter approval. Individual or class action enforcement suits may be filed and shall have the highest civil priority of resolution. Successful plaintiffs are allowed costs and reasonable attorney fees, but a district is not unless a suit against it be ruled frivolous. Revenue collected, kept, or spent illegally since four full fiscal years before a suit is filed shall be refunded with 10% annual simple interest from the initial conduct. Subject to judicial review, districts may use any reasonable method for refunds under this section, including temporary tax credits or rate reductions. Refunds need not be proportional when prior payments are impractical to identify or return. When annual district revenue is less than annual payments on general obligation bonds, pensions, and final court judgments, (4)(a) and (7) shall be suspended to provide for the deficiency.

(2) Term definitions. Within this section: (a) "Ballot issue" means a non-recall petition or referred measure in an election. (b) "District" means the state or any local government, excluding enterprises. (c) "Emergency" excludes economic conditions, revenue shortfalls, or district salary or fringe benefit increases. (d) "Enterprise" means a government-owned business authorized to issue its own revenue bonds and receiving under 10% of annual revenue in grants from all Colorado state and local governments combined. (e) "Fiscal year spending" means all district expenditures and reserve increases except, as to both, those for refunds made in the current or next fiscal year or those from gifts, federal funds, collections for another government, pension contributions by employees and pension fund earnings, reserve transfers or expenditures, damage awards, or property sales. (f) "Inflation" means the percentage change in the United States Bureau of Labor Statistics Consumer Price Index for Denver-Boulder, all items, all urban consumers, or its successor index. (g) "Local growth" for a non-school district means a net percentage change in actual value of all real property in a district from construction of taxable real property improvements, minus destruction of similar improvements, and additions to, minus deletions from, taxable real property. For a school district, it means the percentage change in its student enrollment. (3) Election provisions. (a) Ballot issues shall be decided in a state general election, biennial local district election, or on the first Tuesday in November of odd-numbered years. Except for petitions, bonded debt, or charter or constitutional provisions, districts may consolidate ballot issues and voters may approve a delay of up to four years in voting on ballot issues. District actions taken during such a delay shall not extend beyond that period. (b) At least 30 days before a ballot issue election, districts shall mail at the least cost, and as a package where districts with ballot issues overlap, a titled notice or set of notices addressed to "All Registered Voters" at each address of one or more active registered electors. The districts may coordinate the mailing required by this paragraph (b) with the distribution of the ballot information booklet required by section 1 (7.5) of article V of this constitution in order to save mailing costs. Titles shall have this order of preference: "NOTICE OF ELECTION TO INCREASE TAXES/TO INCREASE DEBT/ON A CITIZEN PETITION/ON A

REFERRED MEASURE. " Except for district voter-approved additions, notices shall include only:

(i) The election date, hours, ballot title, text, and local election office address and telephone number.

(ii) For proposed district tax or bonded debt increases, the estimated or actual total of district fiscal year spending for the current year and each of the past four years, and the overall percentage and dollar change.

(iii) For the first full fiscal year of each proposed district tax increase, district estimates of the maximum dollar amount of each increase and of district fiscal year spending without the increase.

(iv) For proposed district bonded debt, its principal amount and maximum annual and total district repayment cost, and the principal balance of total current district bonded debt and its maximum annual and remaining total district repayment cost.

(v) Two summaries, up to 500 words each, one for and one against the proposal, of written comments filed with the election officer by 45 days before the election. No summary shall mention names of persons or private groups, nor any endorsements of or resolutions against the proposal. Petition representatives following these rules shall write this summary for their petition. The election officer shall maintain and accurately summarize all other relevant written comments. The provisions of this subparagraph (v) do not apply to a statewide ballot issue, which is subject to the provisions of section 1 (7.5) of article V of this constitution.

(c) Except by later voter approval, if a tax increase or fiscal year spending exceeds any estimate in (b)(iii) for the same fiscal year, the tax increase is thereafter reduced up to 100% in proportion to the combined dollar excess, and the combined excess revenue refunded in the next fiscal year. District bonded debt shall not issue on terms that could exceed its share of its maximum repayment costs in (b)(iv). Ballot titles for tax or bonded debt increases shall begin, "SHALL (DISTRICT) TAXES BE INCREASED (first, or if phased in, final, full fiscal year dollar increase) ANNUALLY. . . ?" or "SHALL (DISTRICT) DEBT BE INCREASED (principal amount), WITH A REPAYMENT COST OF (maximum total district cost), . . . ?"

(4) Required elections. Starting November 4, 1992, districts must have voter approval in advance for:

(a) Unless (1) or (6) applies, any new tax, tax rate increase, mill levy above that for the prior year, valuation for assessment ratio increase for a property class, or extension of an expiring tax, or a tax policy change directly causing a net tax revenue gain to any district.

(b) Except for refinancing district bonded debt at a lower interest rate or adding new employees to existing district pension plans, creation of any multiple-fiscal year direct or indirect district debt or other financial obligation whatsoever without adequate present cash reserves pledged irrevocably and held for payments in all future fiscal years.

(5) Emergency reserves. To use for declared emergencies only, each district shall reserve for 1993 1% or more, for 1994 2% or more, and for all later years 3% or more of its fiscal year spending excluding bonded debt service. Unused reserves apply to the next year's reserve.

(6) Emergency taxes. This subsection grants no new taxing power. Emergency property taxes are prohibited. Emergency tax revenue is excluded for purposes of (3)(c) and (7), even if later ratified by voters. Emergency taxes shall also meet all of the following conditions:

(a) A 2/3 majority of the members of each house of the general assembly or of a local district board declares the emergency and imposes the tax by separate recorded roll call votes.

(b) Emergency tax revenue shall be spent only after emergency reserves are depleted, and shall be refunded within 180 days after the emergency ends if not spent on the emergency.

(c) A tax not approved on the next election date 60 days or more after the declaration shall end with that election month.

(7) Spending limits. (a) The maximum annual percentage change in state fiscal year spending equals inflation plus the percentage change in state population in the prior calendar year, adjusted for revenue changes approved by voters after 1991. Population shall be determined by annual federal census estimates and such number shall be adjusted every decade to match the federal census.

(b) The maximum annual percentage change in each local district's fiscal year spending equals inflation in the prior calendar year plus annual local growth, adjusted for revenue changes approved by voters after 1991 and (8)(b) and (9) reductions.

(c) The maximum annual percentage change in each district's property tax revenue equals inflation in the prior calendar year plus annual local growth, adjusted for property tax revenue changes approved by voters after 1991 and (8)(b) and (9) reductions.

(d) If revenue from sources not excluded from fiscal year spending exceeds these limits in dollars for that fiscal year, the excess shall be refunded in the next fiscal year unless voters approve a revenue change as an offset. Initial district bases are current fiscal year spending and 1991 property tax collected in 1992. Qualification or disqualification as an enterprise shall change district bases and future year limits. Future creation of district bonded debt shall increase, and retiring or refinancing district bonded debt shall lower, fiscal year spending and property tax revenue by the annual debt service so funded. Debt service changes, reductions, (1) and (3)(c) refunds, and voter-approved revenue changes are dollar amounts that are exceptions to, and not part of, any district base. Voter-approved revenue changes do not require a tax rate change.

(8) Revenue limits. (a) New or increased transfer tax rates on real property are prohibited. No new state real property tax or local district income tax shall be imposed. Neither an income tax rate increase nor a new state definition of taxable income shall apply before the next tax year. Any income tax law change after July 1, 1992 shall also require all taxable net income to be taxed at one rate, excluding refund tax credits or voter-approved tax credits, with no added tax or surcharge.

(b) Each district may enact cumulative uniform exemptions and credits to reduce or end business personal property taxes.

(c) Regardless of reassessment frequency, valuation notices shall be mailed annually and may be appealed annually, with no presumption in favor of any pending valuation. Past or future sales by a lender or government shall also be considered as comparable market sales and their sales prices kept as public records. Actual value shall be stated on all property tax bills and valuation notices and, for residential real property, determined solely by the market approach to appraisal.

(9) State mandates. Except for public education through grade 12 or as required of a local district by federal law, a local district may reduce or end its subsidy to any program delegated to it by the general assembly for administration. For current programs, the state may require 90 days notice and that the adjustment occur in a maximum of three equal annual installments.

Constitution of the State of Colorado, Article II, Section 24. Right to assemble and petitionSection page →

The people have the right peaceably to assemble for the common good, and to apply to those invested with the powers of government for redress of grievances, by petition or remonstrance.

Constitution of the United States, Amendment ISection page →

Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.

Powers the people kept for themselves

Article V, Section 1 vests legislative power in the General Assembly, "but the people reserve to themselves the power to propose laws and amendments to the constitution and to enact or reject the same at the polls independent of the general assembly."

The initiative

  • Signatures equal to 5% of all votes cast for Secretary of State at the last general election are needed to put a statute or amendment on the ballot (Section 1(2)), filed with the Secretary of State at least three months before the general election.
  • Since 2016 (Amendment 71), an initiated constitutional amendment also needs signatures from 2% of registered voters in every state senate district (Section 1(2.5)), and must win at least 55% of the vote unless it only repeals part of the constitution (Section 1(4)(b)).
  • Each measure must contain a single subject clearly expressed in its title (Section 1(5.5)), and drafts get a public review-and-comment meeting with the legislature's nonpartisan staff before a ballot title is set (Section 1(5)).
  • The Governor cannot veto a measure the people adopt (Section 1(4)(a)).

The referendum

Voters may demand a vote on any act of the General Assembly, or any part of one (except laws "necessary for the immediate preservation of the public peace, health, or safety" and appropriations for the support and maintenance of state departments and institutions), by a petition with signatures equal to 5% of the last vote for Secretary of State, filed no more than 90 days after final adjournment of the session that passed the bill; or the legislature may refer a measure itself (Section 1(3)). Constitutional amendments proposed by the legislature need two-thirds of all members elected to each house and the same 55% vote of the people, unless they only repeal (Article XIX, Section 2).

Recall

Article XXI lets voters remove elected state officers, and elected officers of counties, cities and towns, before the end of a term by petition and recall election. To recall a state officer, the petition needs signatures equal to 25% of the entire vote cast for all candidates for that office at the last election (Section 1); for local officers, the procedure is set by law, and the constitution caps the requirement at that same 25% (Section 4). A petition generally cannot be filed until the officer has held office for six months (state legislators may face one five days after the legislature convenes).

The Taxpayer's Bill of Rights

TABOR (Article X, Section 20), adopted by initiative in 1992, requires advance voter approval for new taxes, tax-rate increases, mill levy increases, extensions of expiring taxes and most multi-year government debt (Section 20(4)). It also limits how fast state and local spending may grow (for the state, inflation plus population growth) unless voters approve more, and revenue above the limit is refunded unless voters agree otherwise (Section 20(7)).

Petitioning your officials

Article II, Section 24 protects the right "peaceably to assemble for the common good, and to apply to those invested with the powers of government for redress of grievances, by petition or remonstrance."

  1. Find your legislators. Colorado has 35 state senators and 65 representatives. Christian Vote USA's "My Officials" page finds yours.
  2. Contact them before committee votes. Colorado committees take public testimony in person and remotely; schedules are at leg.colorado.gov.
  3. Read the Blue Book before voting on ballot measures, and read the measure's full text.

Colorado's direct democracy is powerful. Use it carefully: once a measure is in the constitution, only another vote of the people can take it out of the text (though, as Romer v. Evans showed, federal courts can still hold it unenforceable).
