History
HB 1271 was introduced by Representative Andera for the 2026 Regular Session of the South Dakota Legislature (101st Legislative Session). The bill has been filed but has no recorded legislative history yet, meaning it has not been assigned to a committee or received any hearings or votes.
South Dakota's 2026 session convened on January 13, 2026, with crossover scheduled for February 24, 2026. For a bill to remain viable, it typically must pass its chamber of origin before crossover. Given that no action has been recorded, the bill is in its earliest procedural stage, awaiting committee assignment. South Dakota operates annual sessions with relatively short windows, so bills must move quickly to advance.
