In the bill of exceptions transmitted to this court only Napier is named as defendant in error and he has made a motion to dismiss the writ of error in this court on the ground, among others, that an essential party has not been named as defendant in error and served with a copy of the bill of exceptions. Under the facts outlined above, it is clear that Co-Op Cab Co., the defendant in the main suit, has a substantial interest in upholding the judgment of the trial court and is, therefore, a necessary party in this court.
The loan receipt signed by Lydick in this case is identical in wording with the loan receipt in Lowance v. Dempsey, 99 Ga. App. 592 (109 SE2d 318). In that case, it was held in effect that the attorney for the insurance company was not authorized to bring a suit on behalf of the insured solely on the authority of such a loan receipt. In fact, the loan receipt does not in any sense purport to convey authority to the insurance company to bring suit on behalf of the insured against the parties responsible, but obligates the insured to bring the suit himself. In that case, it was held that the record demanded the finding of the superior court that the attorney acting for the insurance company in bringing suit in the name of the insured was without authority and that the plaintiff should be relieved of the consequences of his actions. The motion in this case was a direct attack on the authority of the attorney who purported to represent Lydick and was clearly brought under the terms of Code § 9-603. Under the facts appearing in the record in this case, the trial court erred in denying Lydick’s motion.
Judgment reversed.
