Plaintiff-appellant Carmen Fragoso de Conway (Fragoso), a citizen of New Jersey, appeals from an order of the district court granting summary judgment in favor of certain defendants, including an insurer, Corporación Insular de Seguros (CIS), which became insolvent during the pen-dency of the appeal. We now conclude (1) that there is no compelling reason, based on either
Erie R.R. Co. v. Tompkins,
I. BACKGROUND
Dr. Maria A. Lopez first treated appellant’s mother, Milagros Rodriguez de Fra- *880 goso, as an outpatient. She diagnosed Mrs. Rodriguez’s condition as transient cer-ebrovascular ischemic activity and referred her to Dr. Mojica for a neurological consultation. On October 13, 1984, Mrs. Rodriguez was admitted to Doctor’s Hospital complaining of numbness in her limbs. Dr. Lopez performed a cardiology evaluation the next day. On October 18, Mrs. Rodriguez complained of tightness in her chest. Dr. Lopez sharply reduced the prescribed medication and ordered an electrocardiogram. Later that evening, Mrs. Rodriguez died of heart failure.
Plaintiff’s cousin, Nilda Fragoso de Rodriguez, suspected medical malpractice. In December 1984, she relayed her suspicions to appellant. On January 16, 1985, appellant contacted Attorney Hector Alvarado-Tizol to explore the possibility of a suit. That same day, appellant hand-delivered a letter to Doctor’s Hospital requesting her mother’s medical records. 1 Appellant then returned to New Jersey, leaving matters in her attorney’s hands.
On April 5, 1989 — over four full years after her mother’s death — appellant invoked diversity jurisdiction, 28 U.S.C. § 1332 (1988), and sued Lopez, CIS, and several other health-care providers in Puer-to Rico’s federal district court. (CIS was joined as a defendant pursuant to Puerto Rico’s direct action statute, P.R.Laws Ann. tit. 26, § 2003 (1990).) Following a lengthy period devoted to discovery and pretrial skirmishing, and marked by settlement of the plaintiff’s differences with other named defendants, Lopez and CIS sought summary judgment. On July 13, 1992, the district court found the suit to be barred by Puerto Rico’s one-year statute of limitations governing negligence actions and granted the defendants’ motion.
II. THE REQUEST TO DISMISS THE APPEAL OR STAY PROCEEDINGS
On December 23, 1992, shortly after this appeal had been assigned for hearing, ap-pellees filed a motion relating that, on December 21, 1992, the Puerto Rico Insurance Commissioner (the Commissioner) had petitioned for the liquidation of CIS; that a superior court judge, discerning a $28,000,-000 capital insufficiency, appointed the Commissioner as liquidator of CIS under P.R.Laws Ann. tit. 26, § 4004 (1976); and that the judge had issued an order remitting all claims against CIS to the claims process demarcated within the liquidation proceedings. 3 Appellees requested that the claim underlying the instant appeal be so forwarded (and the appeal dismissed), or, alternatively, that proceedings herein be stayed pendente lite pursuant to a provision of Puerto Rico’s Insurance Code. 4 We granted an interim stay of proceedings and requested supplemental briefing from the parties and the Commissioner. The briefing period having passed, we now consider appellees’ and the Commissioner’s requests that we remit the underlying claim to the liquidator’s claims process or, at least, stay proceedings in this case pending the expiration of the full cooling-off period stipulated in the Insurance Code.
*881 A. The Erie Doctrine.
We start with bedrock: a state court cannot enjoin federal proceedings.
See General Atomic Co. v. Felter,
The truism, however, does not end the matter. Relying on the Rules of Decision Act,
see
28 U.S.C. § 1652 (1988), and the familiar
Erie
doctrine,
A federal court sitting in diversity is not required automatically to follow all particulars of a state court’s process for dispute resolution. Rather,
Erie
and its progeny identify certain principles that must be used to cull wheat from chaff. The “twin aims” animating the
Erie
doctrine are “discouragement of forum-shopping and avoidance of inequitable administration of the laws.”
Hanna v. Plumer,
For one thing, it is inconceivable that a defendant’s differential ability, depending upon whether the suit is brought in a federal or in a commonwealth court, to invoke Puerto Rico’s procedural law anent insolvent insurers after trial and entry of judgment will influence a litigant’s choice of forum. When a plaintiff selects a forum at the commencement of litigation, she is unlikely to weigh the possibility that a defendant’s insurer might become insolvent years later, thus influencing the procedural status of pending appeals. We think, too, that the uncertainty as to how a Puerto Rico appellate court might apply the laws in question would stymie attempted forum-shopping. Although the Commissioner maintains that a commonwealth court would dismiss the appeal against CIS, the forecasted result is by no means certain. The Insurance Code directs a six-month stay of all proceedings against the insolvent insurer. See P.R.Laws Ann. tit. 26, § 3818, quoted supra note 4. While the Commissioner assumes that P.R.Laws Ann. tit. 26, § 4021(1) mandates dismissal of the appeal, 5 he neither suggests how to reconcile this provision with section 3818 nor explains how an appellate proceeding filed against the insurer before the issuance of a liquidation order comes within the contemplation of section 4021. The first Erie consideration, then, does not favor application of Puerto Rico’s Insurance Code provisions to the instant appeal.
For another thing, declining to apply the Commonwealth’s procedural laws here will not advantage Fragoso as compared with similarly, situated, non-diverse plaintiffs.
Cf. Erie,
What is more, Puerto Rico’s insolvent insurers’ liquidation provisions do not bear in the slightest on the substantive outcome of the appeal. These laws provide a procedure through which claims against the insurer can be resolved and its assets equitably distributed. They do not absolve the insurer of any substantive liability. There is no basis for concluding that this court will reach a result regarding the underlying merits of Fragoso’s appeal that is any different from the result that a Puerto Rico court would reach, had it stayed the action, or that the liquidator’s forum would reach, had the action been forwarded there.
Thus, we reject the Commissioner’s argument that the Erie doctrine compels us to dismiss the appeal against CIS and stay the proceeding against Lopez.
B. Relevancy of Burford Abstention.
In the alternative, the Commissioner urges that we abstain from hearing the instant appeal under the rule of
Burford v. Sun Oil Co.,
(1) when there are ‘difficult questions of state law bearing on policy problems of substantial public import whose importance transcends the result in the case then at bar’; or (2) where the ‘exercise of federal review of the question in a case and in similar cases would be disruptive of state efforts to establish a coherent policy with respect to a matter of substantial public concern.’
Id.
at 361,
In light of this recent characterization of
Burford
abstention, we have three reasons for questioning whether the doctrine is at all relevant here. In the first place,
Burford
commands federal courts “sitting in equity” to abjure interference with certain state fora.
NOPSI,
*883
In the second place,
NOPSI
characterizes
Burford
abstention as a doctrine shielding “state administrative agencies” from federal court interference.
Id.
While Puerto Rico’s tailored revision of the Rehabilitation and Liquidation Model Act,
see
P.R.Laws Ann. tit. 26, §§ 4001-4054, sets in place a “comprehensive framework for the liquidation of insolvent insurance companies and the resolution of claims against them,”
Gonzalez v. Media Elements, Inc.,
In the third place,
Burford
abstention is implicated when the federal courts are asked to interfere with state processes by
reviewing
the proceedings or orders of state administrative agencies, ergo, the requirement of “timely and adequate state-court review.”
NOPSI,
C. Applying Burford Abstention.
Even assuming, for argument’s sake, that Burford remains relevant to this genre of litigation, the current situation affords no occasion for abstention. We explain briefly.
This appeal frames no “difficult question[ ] of state law” bearing on significant public policy issues such as would prompt abstention.
NOPSI,
We turn, then, to the second roadway to
Burford
abstention: when federal review will disrupt “state efforts to establish a
*884
coherent policy with respect to a matter of substantial public concern.”
NOPSI,
Be that as it may, we do not believe, in general, that federal court deci-sionmaking of the kind that exists alongside state insurance liquidation proceedings so significantly disrupts state regulatory frameworks to call for abstention. After
NOPSI, Burford
abstention is only appropriate where federal decisionmaking demands “significant familiarity with ... distinctively local regulatory facts or policies.”
NOPSI,
We believe, therefore, that the circuit court cases favoring abstention in insurer insolvency matters are suspect in light of
NOPSI.
9
At any rate, they are distinguishable from the instant case for a number of reasons. First, in nearly all of those cases,
*885
insolvency intervened before the trial court had entered final judgment. Ordinarily, the more embryonic a case, the more significant an interference with the state framework for handling insurance liquidation if the federal tribunal does not yield. A case such as Fragoso’s, where a trial is complete and solely legal questions suitable for federal appellate resolution are pending on appeal, is a very weak candidate for abstention. As we have remarked before, abstention serves “the interests not only of federalism, but of comity and judicial efficiency.”
Medical Malpractice Joint Underwriting Ass’n v. Pfeiffer,
Second, the concerns animating abstention in
Media Elements,
the one case cited
supra
where the
Burford
issue became relevant only on appeal and the court nevertheless abstained, do not apply here. The appeal in
Media Elements
involved a coverage issue and, therefore, the court reasoned that abstention would lessen the risk of inconsistent coverage interpretations.
See Media Elements,
The
Media Elements
panel also observed that compliance with Puerto Rico’s process would reduce the funds which the insurer would have to spend on litigation.
See
We need go no further.
NOPSI
makes clear that
Burford
abstention requires more than a desire to avoid every inconvenience to, or disruption of, a state’s regulatory systems. Otherwise, abstention would be proper “in any instance where a matter was within an administrative body’s jurisdiction.” Chemerinsky,
supra,
at 112. That cannot be the rule. It follows, then, that the mere existence of state procedures, or even the existence of a complex state apparatus designed to handle a specific class of problems, does not necessarily justify abstention.
See Melahn v. Pennock Ins., Inc.,
111. THE ENTRY OF SUMMARY JUDGMENT
The merits of the appeal need not detain us. Summary judgment is appropriate when “the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to judgment as a matter of law.” Fed.R.Civ.P. 56(c). The rule’s mechanics are well known. Once the movant demonstrates “an absence of evidence to support the nonmoving party’s case,”
Celotex Corp. v. Catrett,
In this diversity action, the substantive law of Puerto Rico controls.
See Erie,
In this case, Fragoso admittedly knew of the injury — her mother’s demise— and she was informed shortly thereafter of the possible link between the injury and medical malpractice. She treated this information as credible and acted upon it, promptly retaining an attorney to explore that very nexus. The question in this case, then, is whether appellant’s failure to acquire notice of the person or persons who caused the injury tolled the limitations period.
We, like other courts, recognize that it is unfair, by and large, to bar a tort action by the mere passage of time if a plaintiff, exercising due diligence, cannot ascertain the tortfeasor’s identity. Because self-induced ignorance of the tortfea-sor’s identity will not interrupt the limitations period, “[t]he key inquiry under this prong of the ‘knowledge’ requirement is whether plaintiff knew or ‘with the degree of diligence required by law’ would have known whom to sue.”
Kaiser v. Armstrong World Indus., Inc.,
Under Puerto Rico law, if a plaintiff sues in tort more than a year after the injury took place, she bears the devoir of persuasion with respect to proving that she lacked the knowledge which would have enabled her to sue within the prescriptive period.
See Kaiser,
Moreover, the delay was never credibly explained. Although appellant argued before the district court that difficulties in procuring the hospital record caused the delay, her argument was based on freestanding allegations and was, therefore, appropriately rejected. We have made it crystal clear that, in opposing summary judgment, a litigant “may not rest upon mere allegations in, say, an unverified complaint or lawyer’s brief, but must produce evidence which would be admissible at trial to make out the requisite issue of material fact.”
Kelly v. United States,
The only material of evidentiary weight produced in plaintiff’s opposition to the summary judgment motion was a partial transcript of her deposition — a deposition in which she acknowledged the passage of time but failed to explain it away. Hér counsel’s arguments, contained in a memorandum filed with the district court, did not suffice to bridge this chasm; after all, proffers that depend not on verified facts but “on arrant speculation, optimistic surmise, or farfetched inference” cannot forestall summary judgment.
Kelly,
IV. THE REFUSAL TO RETRACT
In a last-ditch effort to salvage her case, appellant assigns error to the lower court’s denial of her motion for reconsideration. In this instance, the motion for reconsideration added one new ingredient to the mix: a sworn statement from appellant’s cousin, Nilda Fragoso de Rodriguez. The affidavit relates that Nilda accompanied appellant to the lawyer’s office in December, 1984; that the lawyer wanted the decedent’s medical records so that he could have them scrutinized by an expert; that Nilda requested the records from Doctor’s Hospital in January of 1985; that she returned twice more to the hospital (on unspecified dates) before receiving the record on her third trip (the date of which is also unspecified); that she took the record to the attorney; that, later, on a date again unspecified, she returned to the hospital to get “a certified copy of the full record”; that, after a few telephone inquires on unspecified dates, she received the complete record; and that she delivered it to the lawyer the same day (date unspecified). Bereft, as it is, of even approximate dates, this affidavit is manifestly insufficient to *888 turn the tide. It shows, at most, desultory-efforts inadequate to demonstrate diligence in obtaining the records; and, moreover, it wholly fails to suggest any good reason why appellant and her attorney sat complacently by for so long a period of time.
Where, as here, a motion for summary judgment has been granted, “the district court has substantial discretion in deciding whether to reopen the proceediiigs in order to allow the unsuccessful party to introduce new material or argue a new theory.”
Mackin v. City of Boston,
The provisional stay is dissolved, the appellees’ motion for dismissal of the appeal, a statutory stay, or related relief is denied, and the judgment below is affirmed. Costs to appellees.
Notes
. In her deposition, Fragoso speculated that the letter may have been delivered during the spring of 1985. She now concedes that it was delivered on January 16,' 1985.
. When summary judgment was entered, Lopez and CIS were the sole remaining defendants. They are, therefore, the sole appellees.
. The original order was soon amended and we refer herein to the amended version as the Liquidation Order. Paragraph 25 of the Liquidation Order provides that "any claims against [CIS] or its insurers under an insurance policy or any[ ] other kind of claim, be remitted to the Liquidator....”
.The statute provides in pertinent part:
Judicial proceedings [to] which [an] insolvent insurer is an interested party or in which [it] is bound to represent a party in a court of competent jurisdiction in Puerto Rico shall be temporarily suspended for six (6) months or that period in addition to the six (6) months granted by a court with-jurisdiction, from the date the insolvency was determined to permit the [liquidator] an adequate defense of all causes pending action.
P.R.Laws Ann. tit. 26, § 3818 (Supp.1989).
. The language upon which the Commissioner relies states in pertinent part that “no action at law or equity shall be brought against the insurer or liquidator, whether in Puerto Rico or elsewhere, nor shall any such existing actions be maintained or further presented after issuance [of a liquidation order].”
. Prior to
NOPSI,
the Third Circuit considered whether
Burford
abstention is appropriate when a "court is not being asked to provide equitable relief.”
Lac D’Amiante Du Quebec v. American
*883
Home Assurance Co.,
. The estates of insolvent insurance companies are exempt from the operation of the federal bankruptcy laws. See 11 U.S.C. § 109(b)(2) (1988). Thus, the Puerto Rico Insurance Code fashions a format for regulating insurers’ insolvencies, rehabilitations, and liquidations, centralizing proceedings into a single court analogous to a federal bankruptcy court wherein the Commissioner, as an agent of the court, functions as a receiver. See P.R.Laws Ann. tit. 26, § 4008 (1976).
. In Media Elements, no one opposed the request for abstention. We granted it by summary order, without extensive analysis.
. This view is neither original nor exclusive to us.
See
Erwin Chemerinsky,
Federal Jurisdiction
111-12 (Supp.1990) (concluding that
NOPSI
reins in "several ... lower court decisions expansively interpreting
Burford
abstention”). One decision specially mentioned by Professor Chemerinsky is
Lac DAmiante,
. We note in passing that, while Media Elements was decided after NOPSI, the order for abstention neither cited NOPSI nor acknowledged its suzerainty.
. Neither the Commissioner nor the appellees have contended that any idiosyncracy in Puerto Rico’s direct action statute, P.R.Laws Ann. tit. 26, § 2003, compels a different result. Because of this fact, and because of the utter lack of prejudice to the insurer in the posture of this case, we do not reach the question of whether a liquidator of an insolvent Puerto Rico insurance company may have greater rights to insist upon a local forum when the company is a party to the underlying suit solely by virtue of the direct action statute.
