Under Amendment One, also known as the Taxpayer’s Bill of Rights (TABOR) passed by the voters of Colorado in 1992, a constitutional limit was placed on both revenues and expenditures of state and local governments. Without voter approval, both are limited to the increase in inflation plus the population growth rate. TABOR & Referendum C
