Ganey, Freedman and Seitz, Circuit Judges.
Plaintiff appeals from a judgment entered against her in the district court without trial after we had reversed an earlier judgment for defendant and directed that a new trial be granted. Ratay v. Lincoln National Life Insurance Co., 378 F.2d 209 (3 Cir.), cert denied, 389 U.S. 973, 88 S. Ct. 472, 19 L. Ed. 2d 465 (1967). The appeal deals with the procedure on remand and the quality of evidence required in Pennsylvania where fraud is alleged.
Plaintiff is the beneficiary under a contract between her husband and defendant insurance company insuring the life of her husband. She brought a diversity action governed by Pennsylvania law in the district court which entered judgment in favor of the company after a trial in which a jury returned answers to special interrogatories. On plaintiff's appeal we rejected her contention that she was entitled to judgment in her favor, but awarded her a new trial because the district court had erred in its charge to the jury on the degree of proof by which the company was required to establish its claim that the insured had obtained the insurance fraudulently by giving false answers to questions regarding the present state of his health and his medical history. The district judge had charged the jury that the burden was on the company to prove the elements of fraud by a "fair preponderance of the credible evidence". We held that the burden was on the company to prove the fraud by evidence which was "clear, precise and indubitable" and that the error was a fundamental one which required a new trial even though no proper objection was made. Ratay v. Lincoln National Life Insurance Co., supra. Our opinion was filed on May 16, 1967, and we denied the company's petition for rehearing by the court en banc on June 15, 1967. The Supreme Court of the United States denied certiorari on December 4, 1967.
A few days after the receipt of our mandate in the district court the company filed with it "a motion for an order regarding a new trial". It claimed that on November 14, 1967, four months after our decision, the Supreme Court of Pennsylvania had ruled in Greenberg v. Aetna Insurance Co., 427 Pa. 494, 235 A.2d 582 (1967), that an instruction that fraud need be proven only by a fair preponderance of the evidence was correct under Pennsylvania law and that on the retrial of this case the district court would be required to repeat its earlier charge.
The district court, agreeing with these views, ordered the proceedings stayed, and certified pursuant to 28 U.S.C. § 1292(b) that its order involved a controlling question of law as to which there was substantial ground for difference of opinion and that an immediate appeal from its order might materially advance the ultimate determination of the litigation. The order also directed that if an application for appeal under § 1292(b) was not made within ten days final judgment should be entered for the company. We denied an application for leave to appeal because the order had merely certified the case for appeal without making an authoritative disposition of the controversy. We directed, however, that our denial of leave to appeal should be "without prejudice to the right of the trial court to enter whatever dispositive order is in its judgment mandated by authoritative judicial decision." Thereupon the district court entered an order directing the entry of judgment in favor of the company. It is from the judgment thus entered that the present appeal has been taken.
The principle upon which the district court relied would indeed require it to apply on retrial the changed Pennsylvania law, notwithstanding our determination to the contrary at a previous stage of the same proceeding. United States v. Schooner Peggy, 5 U.S. (1 Cranch) 103, 110, 2 L. Ed. 49 (1801); Vandenbark v. Owens-Illinois Glass Co., 311 U.S. 538, 543, 61 S. Ct. 347, 85 L. Ed. 327 (1941); Lennig v. New York Life Ins. Co., 130 F.2d 580, 581 (3 Cir. 1942). In the Vandenbark case the Supreme Court said:
"While not insensible to possible complications, we are of the view that, until such time as a case is no longer sub judice, the duty rests upon federal courts to apply state law under the Rules of Decision statute in accordance with the then controlling decision of the highest state court. Any other conclusion would but perpetuate the confusion and injustices arising from inconsistent federal and state interpretations of state law." (p. 543, 61 S. Ct. p. 350.)
This principle, however, is but the recognition of a necessary exception to the general requirement that a trial court must comply strictly with the mandate directed to it by the reviewing court.*fn1 The exception must be confined within its appropriate limits. It is only where there has been clear-cut change in the state law after the federal appellate decision, which clearly compels a different conclusion, that a federal trial court may disregard the mandate it has received. The regular flow of state court decisions on the subject matter of a diversity case does not authorize a general re-examination of a federal appellate court's decision on remand. The appellate decision ordinarily marks the end of a stage of the dispute by declaring the law of the case and does not serve as a threshold for fresh contention on the law. A later state court decision which merely applies settled principles to new factual circumstances and is not a declaration of a new and overruling legal principle may not be exploited as a springboard for repetition of the argument which had been unsuccessfully made on appeal. Such a state court decision may in some cases clarify the unsuccessful party's position and even supply it added strength, but so long as it does not amount to a clear pronouncement that the state law rule is different from what had been declared by the federal appellate court, the district court must carry out the mandate.
In the Lennig case where we recognized the right of a trial court to depart from the strict command of our mandate in the exceptional situation where a subsequent decision of the state supreme court had altered the law we had followed, we made it plain that the change in state law must be clearly apparent from the state court decision. We there found that the later Pennsylvania Supreme Court decision on which the trial court had relied in not following our mandate did not lay down a rule different from what we had taken to be the law of Pennsylvania and we therefore reversed the trial court's judgment. Judge Jones speaking for the Court said:
"If, as the learned trial judge apprehended, the later decision [of the Pennsylvania Supreme Court] * * * interpreted the law of Pennsylvania differently than we had perceived it to be in our earlier opinion, then the court below was quite right in applying to the retrial of this case the rule if and as made plain subsequently by binding state court decision. This is necessarily so. The duty resting upon a federal court, in appropriate circumstances, is to ascertain and apply local law and not to make it. But, where a federal court of appeals in a given case has ascertained and applied what it apprehends to be the pertinent state law, such ascertainment of the local law is binding upon the trial court at the retrial of the case unless it is clearly made to appear by subsequent statute, no more than declaratory, or by binding state court decision that the law of the state was other than what the federal appellate court had understood it to be."*fn2
The question, therefore, is whether, as the district court thought, the Greenberg case announced a new rule of Pennsylvania law which precluded it from applying our prior decision on the retrial.
In Greenberg, a fire insurance company defended its insured's claim for a fire loss on the ground that the fire resulted from incendiarism in which the insured had participated. The insured conceded that the fire was incendiary, but denied any knowledge of the arson. In his charge the trial judge instructed the jury that the burden was on the company to establish "by evidence that is clear, precise and indubitable" its allegation that the insured had instigated the fire in order to defraud the company through the presentation of a false claim. The Supreme Court of Pennsylvania reversed a judgement for the insured on the ground that too heavy a burden of proof had been placed on the company. It held that in a civil action for recovery on a fire insurance policy the defense of arson, even though imputing a crime to the insured, need only be established by a fair preponderance of the evidence. Mr. Justice Eagen, speaking for a unanimous Court, said: "This was the rule adopted in Pennsylvania nearly a century ago in a ...
