Term limits

The South Dakota legislature is one of 15 state legislatures with term limits. Voters enacted the South Dakota Term Limits Act in 1992. That initiative said that South Dakota senators are subject to term limits of no more than four consecutive two-year terms, or eight consecutive years. State senators can run again after they have been out of office for a term.

The South Dakota State Legislature has tried on more than one occasion, each time unsuccessfully, to persuade the state's voters to repeal term limits. The most recent such failed attempt was when Amendment J lost in 2008 by 75-25%.

The first year that the term limits — enacted in 1992 — impacted the ability of incumbents to run for office was in 2000.

Vacancies

Under the state constitution, the Governor is responsible for appointing a replacement in the event a vacancy happens in the senate. There are no deadlines set in the state constitution to when the Governor has to fill the vacancy.
