Leading South Dakota Decisions
- Earll v. Farmers Mutual Insurance Co. of Nebraska, 2025 S.D. 20 — UIM owned-but-not-insured exclusion and public policy.

- Phen v. Progressive Northern Insurance Co., 2003 S.D. 133 — UM coverage and bad-faith standards.
South Dakota’s comparative-negligence doctrine is unusual and should not be reduced to a simple percentage rule. Check current statutes, later cases and the actual policy language for each claim.
