South Dakota voters approved a constitutional amendment in 1992 that included term limitations for members of the United States House of Representatives and United States Senate.

  • United States House of Representatives

  • United States Senate

Term-Limit Rule

Unit of limitation: Elections (consecutive service)

Under the 1992 constitutional amendment:

  • U.S. House:
    A person may not be elected to the U.S. House more than six consecutive two-year terms (12 years).

  • U.S. Senate:
    A person may not be elected to the U.S. Senate more than two consecutive six-year terms (12 years).

Counting method:
Election-based counting of consecutive elections won by the same individual for the same federal office.

Eligibility Architecture

Stint-Permission Regime
(Constitutional · Consecutive-Service · Office-Specific)

South Dakota’s design limited consecutive service but did not impose a lifetime bar. After a break in service, eligibility to run again would be restored.

Enforcement Layer

Election eligibility constraint (nomination / election layer)

The amendment operated by restricting election eligibility after specified consecutive terms in Congress. It did not:

  • regulate ballot printing or ballot labeling, or

  • impose an office-holding disqualification after election.

Governing Text

South Dakota Constitution, Article III, § 32 — Term limitations for United States congressmen.

“Commencing with the 1992 election, no person may be elected to more than two consecutive terms in the United States Senate or more than six consecutive terms in the United States House of Representatives.”

Federal Foreclosure

In U.S. Term Limits, Inc. v. Thornton (1995), the U.S. Supreme Court held that states are prohibited from imposing additional qualifications (including term limits) on Members of Congress beyond those enumerated in the U.S. Constitution. As a result, South Dakota’s congressional term limits have no operative effect for federal office.

Structural Significance

South Dakota’s 1992 constitutional amendment illustrates a state-initiated congressional term-limit regime that applied consecutive-service caps on federal legislative offices at the election-eligibility layer. Structurally, the system treated elections as the operative unit of service aggregation while preserving long-run permission after a hiatus in service.

However, these provisions were categorically foreclosed by U.S. Term Limits, Inc. v. Thornton (1995), demonstrating the federal constitutional boundary restricting states from adding qualifications for Members of Congress.
