478 P.3d 415
Okla.2020Background
- Thurston held three separate six‑month State Farm auto policies (each with UM coverage) and paid separate UM premiums for each vehicle.
- In 2014 the Oklahoma Legislature amended 36 O.S. § 3636(B) (effective Nov. 1, 2014) to prohibit stacking of UM limits unless an insurer "expressly" provides for stacking.
- In 2015–2016 State Farm mailed renewal notices and an "Important Notice" and issued Amendatory Endorsement 6128AP stating UM limits from multiple State Farm policies would not be added together.
- Thurston was injured in a June 9, 2016 accident; State Farm paid only up to the single highest policy limit across his policies and denied further UM benefits.
- Thurston sued claiming State Farm had "expressly" provided for stacking by charging and accepting separate UM premiums (and relied on earlier statements that policies would stack); State Farm asserted its endorsement and notices unambiguously precluded stacking.
- The district court granted summary adjudication for State Farm; the Oklahoma Supreme Court reviewed whether charging separate premiums alone constitutes an "express" provision for stacking under § 3636(B).
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether charging and accepting separate UM premiums on multiple policies constitutes an "express" provision to allow stacking under 36 O.S. Supp. 2014 § 3636(B) | Charging separate premiums for separate UM coverages is an express provision that the coverages stack; it is unjust for insurer to charge for coverage it will not provide | "Expressly provided" requires clear, direct policy language or other unmistakable communication; mere payment/acceptance of premiums does not meet that standard; State Farm issued Endorsement 6128AP and renewal notices disclaiming stacking | Charging/accepting separate premiums alone is insufficient; insurer did not expressly provide for stacking, and endorsement precluded stacking as a matter of law |
| Whether pre‑amendment representations (2012) that policies would stack bind the post‑amendment policies issued/renewed after Nov. 1, 2014 | Past oral/agent statements created an expectation and should control | Policies and statute in effect at issuance/renewal govern; insurers have no affirmative duty to explain UM terms; pre‑amendment statements do not alter later written policy language | Pre‑amendment statements do not control post‑amendment policies; insurer not bound by earlier representations |
| Whether the reasonable‑expectations doctrine requires stacking despite unambiguous policy language | Thurston expected stacking based on earlier discussions and payments | Reasonable‑expectations doctrine applies only when policy terms are ambiguous; here the policy and endorsement were clear and unambiguous | Doctrine inapplicable because policy language and endorsement are unambiguous |
