delivered the opinion of the court:
■ This is an appeal from an order granting summary judgment in favor of the defendant Prestige Insurance Group and against the plaintiffs Mary F. Marsh and Juanita Artis. Marsh was an owner of an automobile insured by the defendant. While she was driving and Artis was a passenger she became involved in an accident with two other vehicles. One of the vehicles was an unknown hit-and-run car and the other vehicle was driven by Tommie Lindsay, Jr., who was insured by another insurance company. The plaintiffs brought this action to compel arbitration under the uninsured motorist provision of the policy issued by Prestige.
The defendant moved for a summary judgment on the ground that the plaintiffs had entered into a settlement and executed releases in favor of Lindsay. The defendant contends that that settlement violated two provisions of the contract of insurance.
The defendant’s first contention is based on a provision in the policy reciting that the company shall be subrogated to all of the insured’s rights to recovery and “The insured shall do nothing after loss to prejudice such rights.” The defendant argues that the release of one joint tort-feasor, Lindsay, also released the uninsured motorist and thereby prejudiced the subrogation claim against the uninsured motorist.
To be entitled to a motion for summary judgment under section 57 of the Civil Practice Act (Ill. Rev. Stat. 1975, ch. 110, par. 57) the defendant here must prove that there “is no genuine issue as to any material fact.” A summary judgment will not be granted unless the moving party’s right to that judgment is clear and free from doubt. (Ruby v. Wayman (1968),
The defendant also contends that coverage should be denied under the exclusions provision which provides that the policy does not apply under the uninsured motorist coverage if the insured makes any settlement with anyone who may be legally liable “* # ” without written consent of the company, * * The defendant relies on the case of Tuthill v. State Farm Insurance Co. (1974),
In the recent case of M.F.A. Mutual Insurance Co. v. Cheek (1977),
In the case at bar the exclusion under consideration applies specifically to uninsured motorist coverage. The apparent purpose of such a provision is to protect the subrogation rights of the insurer. Unless those rights are jeopardized we do not believe that the insurer should be allowed to be relieved of its responsibility under the contract. We believe the appropriate rule to be applied in this situation is the same as that which was applied in M.F.A. Mutual Insurance Co., that is, the insurer must show that the alleged breach substantially prejudiced the insurer. On this motion for summary judgment there is a genuine issue of material fact as to whether the defendant has been prejudiced in its subrogation rights by the plaintiff’s settlement without the written consent of the company.
For the reasons stated, the judgment of the circuit court of Cook County is reversed and the cause is remanded for such further proceedings as may be consistent with this opinion.
Reversed and remanded.
McNAMARA and SIMON, JJ., concur.
