Eugene A. CEMER, Plaintiff-Appellant, v. MARATHON OIL COMPANY, Defendant-AppelleeEugene A. CEMER, Plaintiff-Appellant, v. MARATHON OIL COMPANY, Defendant-Appellee
Plаintiff Cerner, a former employee of Marathon Oil Company, was discharged on July 9, 1971. He first filed suit in the United States District Court for the Northern District of Ohio, alleging that his termination violated the Age Discrimination in Employment Act,
Shortly thereaftеr Cerner filed a second action in Michigan state court, claiming that his discharge cоnstituted a breach of his employment contract. Invoking diversity jurisdiction, Marathon removеd the case to the United States District Court for the Eastern District of Michigan and moved the district court to dismiss the second suit on the ground that it was barred by res judica-ta. The district court, ruling that the judgment in the Northеrn District of Ohio constituted “a prior final adjudication on the merits on the same causе of action between these parties”, entered judgment for Marathon. We affirm.
The sole issue presented in this appeal is whether state or federal law governs the splitting of a cause of action.
Appellant urges that the
Erie
doctrine requires the application of Michigаn law in adjudicating the contract claim, citing
McConnell v. Travelers Indemnity Co.,
Unlike the cases above, however, the district court here was obliged to consider the effect of a prior judgment issued by the federal district court in Ohio. As the Second Circuit observed in
Kern v. Hettinger,
One of the strongest policies a court can have is that of determining the scope оf its own judgments. Cf.
Byrd v. Blue Ridge Rural Electric Cooperative, Inc.,
1958,
Unless the court in its order for dismissal otherwise specifies, a dismissal under this subdivision and any dismissаl not provided for in this rule, other than a dismissal for lack of jurisdiction, for improper venue, or for failure to join a party under Rule 19, operates as an adjudication upon the merits.
The order of the district court in the first suit did not provide that the judgment was not on the merits. Absеnt such limiting language, the judgment operates as an adjudication on the merits under
Where two successive suits seek recovery for the same injury, a judgment on the merits operatеs as a bar to the later suit, even though a different legal theory of recovery is advanced in the second suit.
Baltimore S.S. Co. v. Phillips,
Affirmed.
Notes
. Cerner argues in effect that the Ohio suit should have bеen dismissed for lack of jurisdiction under
. The Ohio district court would have been obligated to accept jurisdiction over the contract claim had it been joined in the first suit. Sеe
