Colorado — Amendment 12 (1996)


Overview

Colorado voters adopted Amendment 12 (1996), establishing a system of voter instruction concerning congressional term limits and requiring certain candidates to declare support for a constitutional amendment imposing term limits on Members of Congress.

The amendment directed Colorado’s congressional delegation to support the proposed amendment and created procedures for recording candidate declarations regarding the instruction.

The measure formed part of the ballot-instruction phase of congressional term-limits reform that followed U.S. Term Limits, Inc. v. Thornton (1995).

Measure Identification

  • Measure name: Amendment 12

  • Year: 1996

  • Adoption method: Citizen initiative constitutional amendment

  • Election date: November 5, 1996

  • Result: Approved

Ballot Language

Amendment 12 amended the Colorado Constitution to instruct Colorado’s Members of Congress to support a constitutional amendment establishing congressional term limits.

The measure also created procedures allowing congressional candidates to declare their position regarding the voter instruction.

Institutional Architecture

Voter Instruction Mechanism

The amendment instructed Colorado’s Members of Congress to support a constitutional amendment imposing term limits of:

  • three terms for Members of the House of Representatives

  • two terms for Members of the Senate

The instruction was expressed as a directive from Colorado voters to their federal representatives.

Ballot Information Architecture

Unlike several other 1996 initiatives, Colorado’s measure did not primarily rely on ballot informational statements attached to candidate names.

Instead, the system relied on candidate declarations recorded through election administration procedures.

This produced an informational system based on recorded candidate declarations rather than mandatory ballot statements attached to candidate names.

Candidate Declaration / Pledge Mechanism

The amendment created a mechanism allowing congressional candidates to declare whether they supported the voter instruction regarding term limits.

Candidates who declined to support the proposed amendment could be identified through the declaration system established by the measure.

The declarations were recorded through election administration processes and served as the primary mechanism for communicating candidate positions regarding the instruction.

Election Administration

Ballot Implementation

Colorado’s system relied primarily on the recording of candidate declarations rather than mandatory informational statements printed on ballots.

Election officials were responsible for administering the declaration procedures created by the amendment.

Administrative History

The declaration system remained part of Colorado’s constitutional framework following adoption of Amendment 12.

The declaration system remained part of Colorado’s constitutional framework following adoption of Amendment 12. Litigation concerning the administration of the instruction system later arose in Morrissey v. Colorado.

Litigation History

Colorado’s instruction measure became involved in litigation concerning the administration of ballot informational systems related to congressional term limits.

Relevant litigation included:

Morrissey v. Colorado

The case addressed aspects of Colorado’s implementation of the instruction and declaration system established by Amendment 12.

Relationship to Cook v. Gralike (2001)

The Supreme Court’s decision in Cook v. Gralike addressed ballot informational statements used to favor or disfavor candidates based on policy positions.

Colorado’s system differed structurally from Missouri’s ballot informational statement architecture because it relied primarily on recorded candidate declarations rather than mandatory ballot statements attached to candidate names.

Institutional Design Observations

Colorado’s measure illustrates an alternative design within the Ballot Instruction Phase.

Instead of attaching informational statements directly to candidate names on election ballots, the amendment relied on a candidate declaration system to communicate positions regarding the voter instruction.

This structure distinguished Colorado’s measure from several other instruction-phase initiatives adopted in 1996.
