Section 20.The Taxpayer's Bill of Rights.(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
