How South Dakota’s Government Works

South Dakota holds a place in American political history as the first state to adopt the citizen initiative and referendum, in 1898 — pioneering the direct-democracy tools that spread across the country. A part-time Legislature meets on one of the shortest calendars anywhere, beneath a plural executive, in a small, citizen-run government.

The Executive Branch — Who Runs the State

South Dakota has a plural executive of statewide elected officials: the Governor, the Lieutenant Governor, the Secretary of State, the Attorney General, the State Treasurer, the State Auditor, the Commissioner of School and Public Lands, and the three-member Public Utilities Commission. Since the 1970s the Governor and Lieutenant Governor have run together as a single ticket; most of the others are elected independently, though a few down-ballot officers are chosen at party conventions before facing voters.

With several officers elected on their own, the Governor leads the executive branch but shares authority with colleagues who answer to the voters. The Governor appoints the heads of the executive agencies that aren’t separately elected.

The Legislature — Who Writes the Laws

The South Dakota Legislature is bicameral: a 35-seat State Senate and a 70-seat House of Representatives, with all members serving two-year terms and limited to four consecutive terms (eight years) per chamber. It is a part-time, citizen legislature, with low pay ($16,348 a year for the 2025 session, plus a per diem), so members generally hold other jobs.

The defining feature is the calendar. South Dakota’s session is among the shortest in the country: the constitution provides for roughly 40 legislative days in odd-numbered years and about 35 in even years, convening each January. Everything, including the budget, must be done in that brief window, which keeps the body firmly part-time and citizen-run.

How a Bill Becomes Law

A bill is introduced, referred to committee, and — if it advances — voted on the floor of each chamber within the short session, with differences reconciled before final passage. The Governor can sign a bill, veto it, or let it become law, and holds a line-item veto over appropriations; a veto override takes two-thirds of each chamber. South Dakota also gives its governor an unusual "amendatory" or style-and-form veto, allowing the governor to return a bill with recommended changes for the Legislature to consider.

South Dakota’s signature contribution to American government is direct democracy itself: in 1898 it became the first state in the nation to adopt the citizen initiative and referendum, letting voters write their own statutes and repeal laws passed by the Legislature. The tools South Dakota pioneered then spread across the West and beyond, and South Dakotans still use them regularly today.

What the Governor Can (and Can’t) Do

The Governor appoints the heads of the non-elected agencies, proposes the budget, can call special sessions, holds emergency powers, wields a line-item veto plus the amendatory veto, and holds the clemency power (with a Board of Pardons and Paroles advising). Because the Legislature meets so briefly, the Governor’s control of administration the rest of the year gives the office substantial practical reach.

The main internal checks are the independently elected Attorney General, Secretary of State, Treasurer, Auditor, and other down-ballot officers, the two-thirds override, and — fittingly for the state that invented them — the citizen initiative and referendum, which let voters act when the Legislature will not.

The Courts

South Dakota uses merit selection plus retention for its Supreme Court and elections for its trial courts. The Governor appoints Supreme Court justices from a Judicial Qualifications Commission’s list, and those justices then face periodic up-or-down retention votes; Circuit Court judges are elected in nonpartisan races. The Supreme Court of South Dakota sits at the top, above the trial-level Circuit Courts; the state has no separate intermediate appeals court, so the Supreme Court hears appeals directly.

What makes South Dakota’s government distinctive

  • The first state in the nation to adopt the citizen initiative and referendum, in 1898 — pioneering tools that spread nationwide.
  • One of the shortest legislative sessions in the country — roughly 40 days in odd years and 35 in even years.
  • The governor holds an unusual amendatory veto, able to return a bill with recommended changes.
  • A small, low-paid, citizen legislature ($16,348 a year for the 2025 session) with eight-year per-chamber term limits.
  • A plural executive that includes an elected Commissioner of School and Public Lands and an elected Public Utilities Commission.

Frequently asked questions

Was South Dakota really the first state with ballot initiatives?

Yes. In 1898 South Dakota became the first state in the country to adopt the citizen initiative and referendum, allowing voters to write their own statutes and to repeal laws passed by the Legislature. It was a landmark of the Progressive and Populist movements, and the direct-democracy tools South Dakota pioneered soon spread to many other states, especially in the West.

How long is the South Dakota legislative session?

Very short — among the shortest in the country. The Legislature meets about 40 legislative days in odd-numbered years and roughly 35 in even years, convening each January. Everything, including the budget, must be finished in that brief window, which keeps South Dakota’s a part-time, citizen legislature.

What is South Dakota’s amendatory veto?

It is an unusual power, called a "style-and-form" veto, that lets the governor return a bill to the Legislature with recommended changes rather than simply signing or rejecting it. The Legislature can then accept the governor’s revisions by a simple majority or reject them. South Dakota’s Legislative Research Council describes this style-and-form veto as unique to South Dakota — no other state has adopted it. (A handful of other states give their governors a broader "amendatory" veto, but not this specific style-and-form form.)

Can South Dakota voters pass their own laws?

Yes — and the state takes special pride in it as the birthplace of the practice. Citizens can enact statutes and propose constitutional amendments by initiative and overturn laws by referendum, each by gathering enough valid signatures and winning a majority at the ballot. South Dakotans still use these tools regularly.

Are there term limits in the South Dakota legislature?

Yes. Members are limited to four consecutive terms — eight years — in a single chamber, after which they must leave that chamber, though many move to the other one or return after a break.
