The question presented by this appeal is whether the appellee Bus Company may maintain a tort action against its insurer, appellant, for negligence аnd bad faith in failing to settle a damage suit within the coverage limits of its policy of insurance, where the full amount, of the Bus Company’s liability in excess of such policy was paid to the Bus Company by another *9 insurer under the terms of an excess insurance policy issued by it.
On June 1, 1945, the appellant, American Fidelity and Casualty Company, hereinаfter called the primary insurer, issued a public liability policy to the Bus Company with a maximum coverage of $10,000 for injury to any one person. On the same day, the Security Mutual Casualty Company, hereinafter called the excess insurer, issued to the Bus Company an excess loss policy which referred to .the primary policy and provided coverage for only that part of any loss in excess of $10,000, but not in excess of $100,000 for injury to any one person. By the terms of these policies, the insurers were required to defend all litigation against the Bus Company involving matters covered by the policies.
On July 5, 1945, while the above policies were in full force, a bus operatеd by the Bus Company was involved in an accident in which a passenger, Miss Lorena Lairson, was injured. On August 23, 1945, Miss Lairson filed suit against the Bus Company and the primary insurer, seeking $30,-500 damages for personal injuries. When that case was called for trial, Miss Lair-son’s attorneys offered to settle for $5000, but this offer was refused by the defendant’s attorney at the directiоn of the primary insurer who was in fact conducting this litigation. The case proceeded to trial, and verdict and judgment of $25,000 was rendered in favor of Miss Lairson. The excess insurer took no part whatever in the case. While an appeal from this judgment was pending, the parties compromised the case for $17,500. The Bus Company paid $7,500 of the above settlement, and was reimbursed in like amount by the excess insurer pursuant to the terms of the excess policy. The excess insurer then demanded that the Bus Cоmpany assert a claim against'the primary insurer and this suit was apparently brought in response to that demand. The primary insurer moved to dismiss inter alia on the grounds that the Bus Company was not the real party in interest, having been fully reimbursed for all sums of money it had been required to expend in the settlement of the claim.
The trial court overruled the motion, finding that the primary insurer had been grossly negligent in the investigation and defense of the claim, and that it had been guilty of bad faith in not accepting the original offer of settlement. Judgment was rendered in favor of the Bus Company for $7,500, and this appeal followed.
When an insurance company acts on behalf of the insured in the сonduct of litigation and the settlement of claims, it assumes a fiduciary relationship and is obliged to act in good faith in representing the interests of the insured. American Casualty Co. v. G. A. Nichols Co., 10 Cir.,
Ordinarily when a public liability insurance company fully reimburses its insured for losses within the coverage of the policy, it becomes subrogated to the rights of the insured against third parties whose tortious conduct caused the loss. Travelers Ins. Co. v. Great Lakes Engineering Works Co., 6 Cir.,
We do not believe that a different result is indicated by the Oklahoma statute which provides, “Every action must be prosecuted in the name of the real party in interest * * ' * but this section shall not be deemed to authоrize the assignment of a thing in action, not arising out of contract.” 12 O.S.A. § 221. We are not primarily concerned with the real party in interest portion of the statute, for in this cоurt that question is one of federal law interpreting Rule 17(a). However, in determining who is the real party in interest under federal law, we must first ascertain who has the substantive right of action under state law, McWhirter v. Otis Elevator Co., D.C.,
It has been contended by counsel that subrogation is improper here because the primary and excess insurers were equally at fault, and subrogatiоn is not permitted when equities are equal. Fourth Nat’l Bank of Tulsa v. Board of Com’rs,
We conclude that the tort actiоn against the primary insurer which originally inhered in the Bus Company passed to the excess insurer by subrogation, hence the Bus Company was no longer the real party in interest and is not entitled to prosecute this suit. The judgment is reversed.
