Accident Care and Treatment Center v. Csaa General Insurance Co.

Summary

The Supreme Court of Oklahoma held that the settlement release signed by the injured party contained no assignment of lien‑challenging rights to the insurer, that the parol‑evidence rule bars any extrinsic evidence to create such an assignment, and that summary judgment for the medical providers was proper. The Court vacated the Court of Civil Appeals, affirmed the trial court, and remanded for further proceedings consistent with this opinion.
