This appeal involves a relatively small, but important issue. In 1957 defendant-appellant Commerce Oil Refining Corp., a Delaware corporation, brought a diversity action in the United States District Court for the District of Rhode Island against plaintiffs-appellees Miner et al., residents of the island of Conanicut, Rhode Island, hereinafter collectively Miner. The complaint sought damages for conspiracy and an injunction preventing Miner from interfering with Commerce’s proposed erection of an oil refinery upon the island pursuant to a license from the local authorities. Miner filed a counterclaim asking for a declaration that the license was invalid and for .an injunction against the erection of the refinery as a potential nuisance. The case was reached for trial in March 1958, at which time Commerce abandoned its complaint without offering evidence, the complaint was dismissed with prejudice, and the trial proceeded upon the counterclaim. Thereafter the court made determinations in favor of Miner. These were reversed in this court, and the counterclaim was dismissed. Commerce Oil Refining Corp. v. Miner, D.C.R.I., 1959,
Commerce’s motion to dismiss, so far as the statute of limitations was concerned, hinged upon the applicability of Rhode Island Gen.Laws § 9-1-14 (1956), which limits to two years actions for “injuries to the person.” 1 Whether this statute is applicable to a suit for malicious use of process has never been considered by the Rhode Island courts. The district court correctly pointed out that courts elsewhere, interpreting similar statutes, are divided. Under the circumstances the district court’s decision as to local law was at best, as the court stated, an “informed prophecy” as to which line the Rhode Island court would adopt.
Promptly after the denial of its motion to dismiss herein, Commerce brought an action for a declaratory judgment in the Rhode Island Superior Court, alleging the controversy between it and Miner *127 as to the meaning of the statute and the novelty and importance of the question and requesting an “authoritative decision.” Thereafter it moved in the district court for a stay pending the outcome of the state proceedings. Miner countered by asking the district court not only to deny the stay but to enjoin the state action. The court acceded to Miner’s requests. After reciting that Miner was “entitled to have the Orders and Judgments of this Court reviewed by the normal procedures for review and ought not to be subjected to litigation in other courts in connection with a ease which is being tried in this Court,” it denied Commerce’s motion and enjoined it from proceeding in the state court. 2 Commerce appeals from the injunction. 28 U.S.C. § 1292(a).
Commonly two purely in person-am suits between the same parties for the same cause of action may not be maintained in the same jurisdiction. Sutcliffe Storage & Warehouse Co. v. United States, 1 Cir., 1947,
In only one respect has Congress disapproved of a broad application of the doctrine of comity. In Toucey v. New York Life Ins. Co., 1941,
“A court of the United States may not grant an injunction to stay proceedings in a State court except as expressly authorized by Act of Congress, or where necessary in aid of its jurisdiction, or to protect or effectuate its judgments.” (28 U.S.C. § 2283) (matter italicized new.) 3
Miner exaggerates the effect of this amendment. We find no suggestion that it was meant to overrule cases such as-Kline. The added exception has two aspects. To generalize a judgment is to be “protected” from action which would frustrate it, and it is to be “effectuated” when, in the language of the Reviser’s Note, the further action would mean “relitigation of cases and controversies fully adjudicated.” 4 It will be seen, on *128 analysis, that any broader interpretation would not merely restrict comity, it would mean competition.
The present case involves neither protection nor effectuation. The former means protection against the loss of substantial rights. On occasion protectible rights may be conferred by something short of a final judgment. Cf. Sperry Rand Corp. v. Rothlein, 2 Cir., 1961,
Furthermore, in this particular situation, in view of the paramount authority of state law, the district court’s decision would be subject to change even after it became final within the conventional sense and was pending on appeal. A decision on pertinent state law is to be welcomed at any time. Vandenbark v. Owens-Illinois Glass Co., 1941,
Possibly the court was misled by certain cases holding it erroneous for a federal court to stay its own hand in order to await a state court decision. Cf. Meredith v. City of Winter Haven, 1943,
Nor do we mean that it is necessary wrong for a district court to await an anticipated decision by a state court on a determinative matter. The present issue does not, like the Harvard College case, involve a question of the application of various principles of law to possibly disputed facts, but is
one
of interpretation of a single state statute which may be dispositive of the entire action, Whether in a particular instance a federal court should stay its hand pending state court action seems to us a highly individual question in which all factors should be considered, the possibly delay,
*129
the relative difficulty of estimating what the state court would decide, the importance to the ease of a state court determination, the relative burden on the parties of a possibly long case in the federal court as against a short one in the state court, and perhaps other matters. The mere prospect of delay is not determinative. United Gas Pipe Line Co. v. Ideal Cement Co., 1962,
There is presently no appeal before us with relation to the district court’s refusal to stay its own action. We leave it to that court whether it may wish to reconsider that matter in the light of this opinion.
Judgment will be entered directing the district court to vacate the injunction; mandate to issue forthwith.
Notes
. Miner’s present cause accrued in March 1958 when Commerce’s complaint was dismissed with prejudice, or, possibly, an issue not before us, never accrued at all because the disposition of the counterclaim negatives lack of probable cause.
. Additionally, the court said that had Commerce requested it in time, it would have certified its order denying the motion to dismiss as appropriate for an immediate appeal under 28 U.S.C. § 1292 (b). It said that in the present posture its ruling was the law of the case.
. The clause immediately preceding was also newly added to this particular statute, hut it previously existed elsewhere. It is, quite properly, not relied upon in the case at bar. Cf. Kline, supra. See 1 Moore, Federal Practice ¶ 0.225 (2d ed. 1960).
. We find no recorded history except the Note, but this is explicit.
“The exceptions specifically include the words ‘to protect or effectuate its judgments,’ for lack of which the Supreme Court held that the Federal courts are without power to enjoin relitigation of cases and controversies fully adjudicated by such courts. (See Toucey v. New York Life Insurance Co.,314 U.S. 118 , *12862 S.Ct. 139 ,86 L.Ed. 100 . A vigorous dissenting opinion (62 S.Ct. 148 ) notes that at the time of the 1911 revision of the Judicial Code, the power of the courts of the United States to protect their judgments was unquestioned and that the revisers of that code noted no change and Congress intended no change). Therefore the revised section restores the basis law as generally understood and interpreted prior to the Toueey decision.”
. Miner’s brief is regrettably full of ad hominem appeals to a federal court’s supposed confidence and pride in its “ability” to determine state law. Our decisions are based on necessity, not superior ability.
