This is аn appeal from a summary judgment entered in favor of the defendants on grounds of res judicata. The appellant FDIC brought this action to enforce an agreement between the defendants and a bank whose assets it had acquired. The FDIC had brought a previous action in the Court of Common Pleas of Cuyahoga County, Ohio, against these same dеfendants to foreclose a mortgage. Since both the present action and the mortgage foreclosure action involved the same underlying debt, and since the Ohio State court action was decided in favor of the defendants, the district court held that the present action was barred by the doctrine of res judicata. We reverse and remand for further proceedings.
I
On November 5, 1974, the Northern Ohio Bank (the Bank) loaned $55,000 to Joseph E. Wurstner, Inc. (Wurstner). Appellee Robert G. Eckhardt was the president of Wurstner. On thаt same day, Mr. Eckhardt and his wife, Joanne, also a codefendant, signed a standard Bank form entitled “Agreement To Be Bound.” Basically, this document provided that the Eckhardts would bе personally and primarily obligated to pay “any and all loans [then] made or [thereafter] to be made” to Wurstner by the Bank. The loan to Wurstner was evidenced by a prоmissory note signed by Robert Eckhardt on behalf of Wurstner.
In addition, the Eckhardts signed a real estate mortgage for their residential property with the Bank as mortgagee. The mortgаge agreement was signed on November 5, 1974, and was recorded on December 12. However, the Eckhardts did not sign a promissory note in their individual capacity as stated in the mortgage agreement.- The only promissory note that was signed was the note executed by Mr. Eckhardt on behalf of Wurstner.
In February 1975, appellant FDIC was appointed recеiver for the assets of the Bank. When Wurstner defaulted on the loan, the FDIC recovered a judgment on the promissory note against Wurstner for $60,641.49 ($55,000 plus interest).
After the FDIC had failed to reаlize any recovery from the judgment against Wurstner, it brought an action in the Court of Common Pleas of Cuyahoga County, Ohio, to foreclose on the mortgage signed by the Eckhardts. The Ohio State Court entered judgment in favor of the Eckhardts. The State court found that, contrary to the terms of the mortgage document, the Eckhardts never executed a promissоry note for $55,000 individually. Therefore, the court held that there was no consideration for the mortgage. The State court rendered judgment for the defendant Eckhardts on June 20, 1978.
The FDIC then brought the present action in the district court. Jurisdiction was *247 based upon 12 U.S.C. § 1819. In this action the FDIC seeks to enforce the terms of the “Agreement To Be Bound” described above and to recover a judgment against the Eckhardts personally in the amount of the judgment against Wurstner, plus interest.
In separate answers, the Eckhardts set forth several affirmative defenses, including the defenses of res judicata and collateral estoppel based upon the prior State court judgment in favor of the defendants. The Eckhardts and FDIC both filed motions for summary judgment.
The district court granted summary judgment for the defendants and dismissed the FDIC’s complaint with prejudice. The court held that the doctrine of res judicata prohibited thе FDIC from maintaining the present action on the Agreement To Be Bound because a recovery based upon the Agreement and a recovery based upon the mortgage were “two different means to the same end, rather than distinctly separate causes of action.” Relying upon the
Restatement of Judgments
§ 65(1) (1942), and
Cerner v. Marathon Oil Co.,
II
The parties agree that the law of Ohio controls on the question of what res judicata effect should be given the prior judgment in the Court of Common Pleas of Cuyahoga County, Ohio. To support its assertion that Ohio law controls, FDIC cites
Wright v. Georgia Railroad & Banking Co.,
FDIC also relies upon the language of 28 U.S.C. § 1738, implementing the Full Faith And Credit Clause of Article IV, § 1 of the United States Constitution. This statute provides that state judgments “shall have the
same
full faith and credit in every court within the United States and its Territories and Possеssions as they have by law or usage in the courts of such State, Territory, or Possession from which they are taken.” (Emphasis added.) Some commentators and courts have stated that a federal court sometimes may apply a federal rule of res judicata and give a
greater
preclusive effect to a state court judgment than accorded by the state’s law.
Lynn Carol Fashions, Inc. v. Cranston Print Works, Co.,
It appears that the emerging rule is that the preclusive effect of a valid judgment is to be determined by thе law of the system which rendered the judgment.
See
Degnan,
Federalized Res Judicata,
85 Yale L.J. 741, 773 (1976);
Restatement (Second) of Conflict of Laws,
§ 95, comment g (1969). See
also General Foods Corp. v. Massachusetts Dept. of Public Health,
Whether a federal rule of res judicata should ever be aрplied to determine the preclusive effect of a state court judgment on issues of state law need not be decided in the present case. We agree with the parties that Ohio law of res judicata applies here.
*248 III
The leading decision of the Ohio Supreme Court which appears to control on the res judicata questiоn presented here is
Norwood v. McDonald,
The Ohio rule, as stated in
Norwood, supra,
In Norwood, supra, the Ohio Supreme Court held that plaintiff could bring a suit alleging that he was entitled to certain property by virtue of his having inherited it from the decedent who was his common law wife, even though he brought a previous action in which he had sued and lost on the theory that the property had been held by the decedent in trust for him and the decedent during her lifetime and passed to him upon her death. The Ohio court found that the action as heir-at-law was a separate cause of actiоn from the action as beneficiary of a trust. The court stated:
The rule that a judgment is conclusive, not only as to what was determined in an action but as to all issues of fact which properly might have been determined therein, is limited to cases involving a single cause of action.... Of course, one cannot split a single cause of action .. ., but when the second action is upon a differеnt claim, or demand, or cause of action, the judgment in the first suit operates as an estoppel only as to the points or questions actually litigated and determined, and not as to other matters which might have been but were not litigated and determined herein.142 Ohio St. at 312-13 ,52 N.E.2d at 74 . (Citations omitted). (Emphasis in original.)
In the present case, we conclude that the cause of action based uрon the “Agreement To Be Bound” is different from the cause of action based upon the mortgage agreement, under the test applied in
Norwood, supra.
The court in
Norwood
stated the test of whether there is a single or two distinct causes of action for res judicata purposes as follows: “Whether different proofs are required to sustain the two actions is said to be the mоst accurate test in determining whether the former action is a bar.”
While the Supreme Court of Ohio has demonstrated a tendency to liberalize its rules of res judicata and сollateral estoppel,
see, e.g., Johnson’s Island, supra,
The decision of the district court is reversed and remanded for further proceedings. We express no opinion as to the merits of the FDIC’s claim or Eckhardts’ other affirmative defenses. No costs are taxed. The parties will bear their own costs on this appeal.
