The South Dakota Supreme Court has issued an advisory opinion affirming that the state's lieutenant governor has the authority to cast tie-breaking votes in the state Senate. Governor Larry Rhoden had requested the court's guidance on the issue, and the court found that relevant articles in the state constitution complement each other to grant the lieutenant governor this power.

Why it matters

This ruling provides clarity on the lieutenant governor's role and helps resolve any ambiguity around the tie-breaking process in the state legislature. It ensures the lieutenant governor can fulfill their constitutional duties as president of the Senate, even in the event of deadlocked votes.

The details

In its advisory opinion, the South Dakota Supreme Court stated that articles in the state constitution granting the lieutenant governor the role of Senate president and allowing the legislature to pass laws by majority vote can be read together. This means the lieutenant governor has the authority to cast a tie-breaking vote when the Senate is deadlocked 18-18.

  • The Supreme Court issued its advisory opinion on Wednesday, February 19, 2026.
