Both Sam Mamet and Larry Sarner acutely remember the moment that the Taxpayer’s Bill of Rights Act was amended to the Colorado Constitution. The difference: One man hated the amendment’s restrictions, while the other saw them as democratically vital.
Friday marked exactly 25 years since the election in which the amendment was added to the state constitution — Nov. 3, 1992. The measure took effect Dec. 31, 1992, and serves as a way to limit the growth of government by requiring increases in overall revenue from taxes not exceed the rates of inflation and population growth.
