Missouri — Amendment 9 (1996)

Overview

Missouri voters adopted Amendment 9 (1996), a statewide constitutional amendment directing Members of Congress to support a constitutional amendment establishing congressional term limits and authorizing informational ballot statements concerning candidate compliance with that instruction.

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

Amendment 9 created a system of voter instruction directed to Members of Congress and required informational statements on election ballots identifying candidates who did not comply with those instructions.

Missouri’s ballot information architecture later produced the litigation that resulted in Cook v. Gralike (2001), which invalidated the ballot-statement system and effectively foreclosed the ballot-instruction pathway that had previously been used during the movement for the Seventeenth Amendment.

  • Adoption method: Citizen initiative constitutional amendment

  • Election date: November 5, 1996

Ballot Language

Amendment 9 added provisions to the Missouri Constitution instructing Members of Congress to support a constitutional amendment establishing congressional term limits.

The amendment required election officials to place informational statements on ballots identifying candidates who failed to comply with voter instruction.

The constitutional text authorized ballot statements including:

  • “DISREGARDED VOTERS’ INSTRUCTION ON TERM LIMITS”

  • “DECLINED TO PLEDGE TO SUPPORT TERM LIMITS.”

These statements were printed adjacent to candidate names on election ballots.

Institutional Architecture

Voter Instruction Mechanism

The amendment instructed Missouri’s Members of Congress to support a constitutional amendment establishing term limits.

The instruction was embedded in the state constitution and expressed as a directive from Missouri voters.

Ballot Information Architecture

The amendment required election officials to attach informational statements to the names of certain candidates on election ballots.

The informational statements indicated whether candidates complied with the voter instruction.

Candidate Declaration / Pledge Mechanism

The amendment permitted candidates to sign a pledge supporting a congressional term-limits amendment.

Candidates declining to sign the pledge were identified on the ballot using informational statements.

Election Administration and Implementation

Missouri election officials implemented the informational statement system in congressional elections following adoption of Amendment 9. The statements were printed on ballots adjacent to candidate names as specified in the constitutional amendment.

Implementation of this system generated litigation challenging the constitutionality of the ballot statements.

Litigation History

The amendment’s ballot-statement provisions were challenged in federal court and ultimately reviewed by the United States Supreme Court in Cook v. Gralike.

The Court held that the ballot statements exceeded the authority granted to states under the Elections Clause because they were designed to influence voter choice rather than regulate the mechanics of congressional elections.

The decision invalidated Missouri’s ballot-statement provisions and effectively ended the ballot-instruction architecture adopted in multiple states during the late 1990s.

Relationship to Cook v. Gralike

The litigation culminating in Cook v. Gralike arose directly from Missouri’s implementation of the ballot informational statement system created by Amendment 9.

Following the decision, the informational statement system was invalidated.

Institutional Design Observations

  • Missouri’s amendment combined three elements that were common in the 1996 ballot-instruction initiatives:

  • voter instruction directing members of Congress to support a congressional term-limits amendment

  • candidate pledge provisions for congressional candidates
    informational ballot statements identifying candidates who declined to support the instruction

These informational statements were intended to communicate to voters whether candidates supported congressional term limits.
