(After stating the foregoing facts.)
1. The intervenor’s relation to the company is that of a holder of an income certificate. The form of the certificate is as follows: “This certifies that J. B. Porter is the owner of twenty certificates, ef the par value of $100 each, of the American Life & Annuity Company, in consideration whereof the holder of this certificate is ’guaranteed to receive, out of the expense fund of said company, a dividend of not less than eight pe£ Cent, per annum upon said ■amount, to be paid semi-annually on the 15th day of July and January in each year hereafter. Any greater dividend than eight *789per cent, shall be paid as declared by the Board of Directors of said company out of said fund. All claims of the holder hereof shall be inferior to the claims of policyholders as against funds of said company; and after the payment of all claims due policyholders, the holder of this certificate shall be entitled to receive his pro-rata share of the assets of said company.” His original intervention was predicated on the basis that he was a creditor by reason of the ownership of the income certificates, and contained substantially the same allegations and prayed the same relief as that contained in the petition of Parker et al., filed in behalf of other certificate-holders; and there was no necessity for two pleadings setting up the same cause of action. Furthermore, the intervenor was not a creditor by virtue of his contract with the company as expressed in his certificate. Lockridge v. State Mutual Life Insurance Co., 142 Ga. 30, 32 (82 S. E. 131). The amendment seeking personal liability against policyholders, by making some of them parties, was clearly without merit.
2. The amendment most earnestly argued in the brief sets up the intervenor’s contention of his right to a reformation of the contract evidenced by the income certificate, on the ground of mutual mistake of law as to the legal effect of the instrument. Intervenor-alleges that he and the company thought that the legal effect of the income certificate was a contract creating a debt in his favor superior to any claim against the company except expenses of operation and claims for death losses of policyholders, and that the contract should be so reformed as to reflect the real intention of the parties. The contract in terms subordinates the rights of the holder of an income certificate to those of policyholders. It would do violence to plain and unambiguous words of the contract to restrict the superiority of the rights of policyholders to death claims. Lockridge v. State Mutual Life Ins. Co., supra. In many jurisdictions no distinction is recognized between a contract made under mistake of law and one made in ignorance of law, and a mistake as to the legal effect of an instrument which conforms to the agreement of the parties is not relievable in equity. It has been held by this court that where money has been paid under a mistake of law, it is recoverable in cases where the other party can not in good conscience retain the money. "The rationale of the rule allowing a recovery of money paid with knowledge of the facts and *790under a mistake of. law is that the plaintiff is not attempting to throw a. loss on any one. If the plaintiff’s recovery would lead to. a-loss on the -part of the defendant, then, the parties being equally innocent,, that fact of itself is sufficient reason for denying the right, of recovery on the plaintiff’s part.” Whitehurst v. Mason, 140 Ga. 148, 154 (78 S. E. 938). In Dolvin v. American Harrow Co., 125 Ga, 699 (3), 704 (54 S. E. 706, 28 L. R. A. (N. S.) 785), it. was held that “an honest mistake of law,' as to the effect of an instrument, on the part of both contracting parties, when such mistake operates as a gross injustice to one and gives an unconscionable advantage to the. other, may be relieved in equity, or under equitable pleadings, in a proper case.” But we do not think this is-a proper case for the reformation of a contract on the ground of mutual mistake of law. The insurance company was a mutual one. The.holders of the policy contracts are entitled both by contract and by law, as against holders of income certificates, to their unearned premiums and to the reserves on their policies which represent-money paid in by them. The policyholders are not parties to the contract of the holders of the income certificates. If-the holders of income certificates were permitted to reform their contract with the insolvent insurance company, it would be at the loss-of;policyholders, and would take from them a fund, produced by the payment- of premiums by them and apply it to the extinguishment of the income certificates. Such a course would be inequitable.-
