Status detailsGov. Rhoden signed SB 175 into law (House 64-3, Senate 28-6) with emergency clause — in effect immediately for first-time registrants (SOS guidance issued Mar 26, 2026). Existing registered voters unaffected. Applies to state elections only. On Jul 10, 2026 the state Board of Elections declined (5-2) an LWV petition to adopt standardizing implementation rules; document-acceptance practices vary by county. On Aug 24, 2026, LWV of South Dakota and a Sioux Falls voter sued the Secretary of State and Board of Elections in federal court (D.S.D.) over implementation (inaccurate rejection notices, no cure process, and the original-only rule for state and tribal IDs) under the Fourteenth Amendment and the Civil Rights Act materiality provision; the suit does not challenge the proof-of-citizenship requirement itself. The complaint cites about 1,500 federal-only registrants since March 2026. The law remains in effect as of Sep 10, 2026.
