Mitа Copystar of America, Inc. (“Mita”) appeals from the district court’s order granting summary judgment and issuing a permanent injunction in favor of Casas Office Machines, Inc. (“Casas”). The action began when Casas sued Mita and two fictitious defendants, John Doe and Richard Roe, in the Superior Court of Puerto Rico, San Juan Part. Organized under the laws of California and with its principal place of business in New Jersey, Mita removed the action to the United States District Court for the District of Puerto Rico. After removal, Casas, by an amendment to its complaint, replaced the fictitious defendants with two named defendants, Caguas Copy, Inc. and Oficentro J.P., Inc., which, like Casas, are Puerto Rico corporations. Complete diversity of citizenship between the parties was thus destroyed, although this fact was not called to the district court’s attention at the time. The district court proceeded to deny Mita’s motions to dismiss and for summary judgment, and it allowed Casas’s motion for a permanent injunction enjoining Mita from impairing a contract entered into with Casas. Now, for the first time on appeal, Mita points out the jurisdictional problem caused by the addition of the nondiverse parties. Mita asks us to vacate the judgment below and order the district court to remand the action to the Superior Court of Puerto Rico. Mitа also attacks the district court’s decision on the merits, arguing that summary judgment was improper and that the district court erred in granting the permanent injunction.
I.
Incorporated in Puerto Rico, Casas sells and distributes office and photocopying equipment in that Commonwealth. In 1983, Casas entered into an agreement with Mita, a supplier of office and photographic equipment, to distribute Mita products in Puerto Rico. As noted, Mita is a California corporation with its principal place of business in New Jersey. Following a period of strained business relations, Casas and Mita executed a second agreement in 1989 (the “1989 Agreement”) granting Casas the exclusive right to distribute Mita’s products in the “Greater San Juan” area. Paragraph 5 of the 1989 Agreement, however, provided that Casas’s inability to meet or exceed 85% of a set sales quota would result in termination of the exclusivity provisions of the contract. Asserting that Casas had failed to achieve the 85% threshold, Mita terminated Casas’s exclusive distribution rights — but retained Casas as a distributor — and designated two new distributors in the “Greater San Juan” area.
Casas responded on February 1, 1991, by suing Mita, John Doe, and Richard Roe 1 in *671 the Superior Court of Puerto Rico, San Juan Part. Casas alleged that (1) Mita had deprived Casas of its exclusive distribution rights without just cause in violation of P.R.Laws Ann. tit. 10, §§ 278-278d 91976) (referred to in the complaint and hereinafter as “Law 75”), (2) defendants had conspired to deprive Casas of its right to sell and distribute Mita products, (3) Mita had impaired Casas’s exclusive distribution agreement, and (4) defendants had intentionally interfered with Casas’s contractual relationship with Mita. Casas sought preliminary and permanent injunctive relief, as well as monetary damages.
Alleging the existence of diversity jurisdiction, Mita removed the action to the United States District court for the District of Puer-to Rico on March 6,1991. Thereafter, Casas amended its complaint twice. An amendment filed on March 9, 1992, added a fifth count, 2 and eliminated Casas’s request for a preliminary (but not a permanent) injunction. By a second motion to amend, brought on May 14, 1992, Casas sought to replace the fictitious defendants with Caguas Copy, Inc. (“Caguas”) and Ofieentro J.P., Inc. (“Oficen-tro”) — the corporations that Mita had designated as new distributors in the Greater San Juan area upon terminating Casas’s exclusive distribution rights. Paragraph 3 of Casas’s Second Amended Complaint read:
Codefendants Caguas Copy, Inc. and Ofi-centro J.P., Inc. are, upon information and belief, corporate entities organized pursuant to the laws of the Commonwealth of Puerto Rico, with Principal offices located at Suite B-3, Goyco Street #10, Caguas, P.R., and Diamаnte Street # %, Villa Blanca, Caguas, P.R., respectively. Said defendants are the corporate and/or judicial entities who together with MITA have conspired, with knowledge of the contractual relationship between MITA and Casas, to deprive the latter of said contrae-tual relationship, directly and indirectly interfering therewith, causing the damages hereinafter itemized. To plaintiffs best knowledge and understanding, Caguas Copy, Inc. and Ofieentro J.P., Inc. are citizens and residents of the Commonwealth of Puerto Rico and are also liable to plaintiff pursuant to the allegations mentioned hereinafter.
(emphasis added). Four days later, on May 18, 1992, Casas moved the district court for an expedited review of its second motion to amend its complaint. Such review was necessary, said Casas, because Ofieentro was under the protection of the United States Bankruptcy Court for the District of Puerto Rico — which had ordered that all creditors file their proof of claims on or before June 8, 1992 — and Casas could not file a proof of claim until its motion to amend was granted. The district court allowed Casas’s second amendment in early June 1992.
In the meantime, Mita had moved for summary judgment on February 12, 1992. It argued primarily that (1) Mita did not impair its contractual relationship with Casas because it merely enforced its rights under the terms of the 1989 Agreemеnt, (2) even if it were found that Mita impaired its contractual relationship with Casas, Mita had just cause to dó so, and (3) Casas’s suit was barred by the equitable doctrine of laches. On March 16, 1992, Casas opposed Mita’s motion for summary judgment, and brought a cross-motion for partial interlocutory summary judgment on its Law 75 claims (Counts One and Three), renewing its request for a permanent injunction. 3 Mita, in turn, filed, on *672 April 13,1992, an opposition to Casas’s cross-motion for summary judgment in which it maintained, inter alia, that (1) permanent injunctive relief is not available under Law 75, and (2) ordering permanent injunctive relief in this case would be unconstitutional. Finally, in a separate motion, filed on June 4, 1992, Mita sought to dismiss Casas’s complaint on the grounds that Casas had engaged in a fraud upon the court.
The United States magistrate judge reviewed Mita’s motions to dismiss and for summary judgment, as well as Casas’s cross-motion for summary judgment. In a report and recommendation issued on September 2, 1993, the magistrate judge concluded that (1) Casas had not committed fraud on the court, (2) Casas was not barred by the doctrine of laches from pursuing its claims under Law 75, (3) Mita did not have just cause under Law 75 to terminate Casas’s exclusive distribution rights because it failed to demonstrate that the quota provision in the 1989 Agreement was reasonable at the time of Casas’s nonperformance, (4) a permanent injunction may be ordered under Law 75, and (5) Mita had impaired its contractual relationship with Casas. Consequently, the magistrate judge recommended that the district court deny Mita’s motions to dismiss and for summary judgment, and grant Casas’s cross-motion for summary judgment.
In its opinion and order filed on November 18, 1993, the district court adopted all of the magistrate judge’s recommendations, thereby granting Casas’s cross-motion for summary judgment on its Law 75 claims (Counts One and Three).

Casas Office Machines v. Mita Copystar Machines,
II.
Before we reach the issue of subject matter jurisdiction, we respond to Casas’s challenge to our appellate jurisdiction. Casas maintains that, under
Carson v. American Brands, Inc.,
The Supreme Court has said that § 1292(a)(1) provides appellate jurisdiction over two types of orders: those “that grant or deny injunctions and [those] that have the practical effect of granting or denying injunctions and have ‘serious, perhaps irreparable, consequence[s].’ ”
Gulfstream Aerospace Corp. v. Mayacamas Corp.,
Here, the district сourt’s order expressly granted Casas’s motion for an injunction barring Mita from impairing the 1989 Agreement without just cause.
Casas,
III.
Mita argues that there is no subject matter jurisdiction in federal court because complete diversity of citizenship was destroyed when the fictitious defendants were replaced with Caguas and Oficentro after removal. Although Mita raises this issue for the first time on appeal, we are obliged to address it because a defense of lack of jurisdiction over the subject matter is expressly preserved against waiver by Fed.R.Civ.P. 12(h)(3).
E.g., Halleran v. Hoffman,
A.
This case involves no federal question. Jurisdiction stands or falls upon diversity of citizenship. It has long been settled that a “lack of ‘complete diversity’ between the parties deprives the fеderal courts of jurisdiction over the lawsuit.”
Sweeney v. Westvaco Co.,
Casas argues that as diversity jurisdiction was established at the commencement of the proceeding, it was not later defeated by the mere naming of the fictitious parties, who were dispensable, not indispensable.
*674
E.g., Freeport-McMoRan Inc. v. K N Energy, Inc.,
As part of the Judicial Improvements and Access to Justice Act of 1988, Pub.L. No. 100-702, 102 Stat. 4669 (1988), Congress enacted 28 U.S.C. § 1447(e) (1988), which provides:
If after removal the plaintiff seeks to join additional defendants whose joinder would destroy subject matter jurisdiction, the court may deny joinder, or permit joinder and remand the action to the State court.
Although this provision relates expressly to joinder, the legislative history to the Judicial Improvements and Access to Justice Act of 1988 indicates that § 1447(e) applies also to the identification of fictitious defendants after removal. H.R.Rep. No. 889,100th Cong., 2d Sess. 72-73 (1988), reprinted i n 1988 U.S.C.C.A.N. 5982, 6033 (“Th[e] provision also helps to identify the consequences that may follow removal of a case with unidentified fictitious defendants.”); e.g., Lisa Combs Foster, Note, Section IW(e) ’s Discretionary Joinder and Remand: Speedy Justice or Docket Clearing?, 1990 Duke L.J. 118, 121, 132 (“[I]f after removal the plaintiff identifies the Doe defendant as a nondiverse party, then pursuant to section 1447(e) the court may either deny joinder or permit joinder and remand.”).
Federal courts and commentators have concluded that, under § 1447(e), the joinder or substitution of nondiverse defendants after removal destroys diversity jurisdiction,
regardless
whether such defendants are dispensable or indispensable to the action.
E.g., Yniques v. Cabral,
Section 1447(e)’s legislative history supports this conclusion. In enacting § 1447(e), Congress considered a proposal that would have allowed the joinder of certain nondi-verse parties and, at the same time, permitted the district court, in its discretion, to keep the ease and decide it on the merits. H.R.Rep. No. 889, 100th Cong., 2d Sess. 72-73 (1988), reprinted in 1988 U.S.C.C.A.N. 5982, 6033-34 (“The most obvious alternative [to § 1447(e) ] would be to provide that ‘the court may deny joinder, dismiss the action, or permit joinder and either remand to the state court or retain jurisdiction.’ ”); see David D. Siegel, Commentary on 1988 Revision of Section 1W, in 28 U.S.C.A. § 1447 (1994); Foster, Note, supra, at 137-38. Congress rejected the proposal, however, because it would have represented a “departure from the traditional requirement of complete diversity,” and “provide[d] a small enlargement of diversity jurisdiction.” H.R.Rep. No. 889, 100th Cong., 2d Sess. 72-73 (1988), reprinted in 1988 U.S.C.C.A.N. 5982, 6033-34. We think that, had Congress decided that federal courts could retain jurisdiction over cases in which plaintiffs joined or substituted dispensable, nondiverse defendants after removal, it would have made that plain in § 1447(e).
This is not to say that it is unimportant whether a nondiverse defendant whom a plaintiff seeks to join or substitute after removal is dispensable or indispensable to the action. If the defendant is indispensable, the district court’s choices arfe limited to denying joinder and dismissing the action pursuant to Fed.R.Civ.P. 19, or else allowing joinder and remanding the case to the state court pursuant to § 1447(e).
See Yniques,
B.
Although diversity jurisdiction was defeated when Caguas and Oficentro were substituted for the fictitious defendants after removal, jurisdiction could be restored retroactively in appropriate circumstances, if Caguas and Oficentro were dispensable parties, by dismissing them from the action. In
Newman-Green, Inc. v. Alfonzo-Larrain,
Courts may not, of course, dismiss indispensable parties from an action in order to preserve federal jurisdiction. But, contrary to Mita’s assertions, we conclude that Caguas and Oficentro are dispensable parties. Mita’s principal contention is that Casas is *676 barred by the doctrine of judicial estoppel from asserting that Caguas and Oficentro are dispensable parties because Casas, in a motion requesting relief from the automatic stay, represented to the United States Bankruptcy Court for the District of Puerto Rico that Oficentro is an indispensable party. In that motion, Casas argued in the bankruptcy court that:
2. Creditor CASAS wishes to duly serve process, litigate and try the above mentioned lawsuit in the U.S. District Court against Debtor [ (Oficentro) ], and the other defendants [ (Mita and Caguas) ] before a jury. If CASAS is not allowed to serve process and litigate its claims against Debtor, CASAS would be effectively precluded from obtaining recovery under its tortious interference and contract in prejudice of third party’s claims, due to a lack of an indispensable party. Concomitantly, CASAS’ constitutional right to have a trial by jury on all its legally tenable claims would be impaired.
(emphasis added).
While this assertion is manifestly at odds with Casas’s present position, we are disinclined under all the circumstances to find that it created an estoppel. Judicial estoppel is a judge-made doctrine designed to prevent a party who plays “fast and loose with the courts” from gaming unfair advantage through the deliberate adoption of inconsistent positions in successive suits.
See Scarano v. Central R.R. Co.,
Mita next argues that Caguas and Oficentro are indispensable parties under a Federal Rules of Civil Procedure 19(b) analysis. It submits that, because the permanent injunction compels it to resume an exclusive distribution relationship with Casas in the Greater San Juan area, Caguas’s and Ofieentro’s contractual rights to distribute Mita products in that area are necessarily canceled. Moreover, Mita points out that Casas is seeking a declaratory judgment decreeing Mita’s distribution agreements with Caguas and Oficentro null and void. Under these circumstances, says Mita, this action cannot “in equity and good conscience” proceed without Caguas and Oficentro, which are entitled to protect their contractual interests. We are not persuaded. A leading commentator writes:
When a person is not a party to the contract in litigation and has no rights or obligations under that contract, even though he may have obligated himself to abide by the result of the pending action by another contract that is not at issue, he will not be regarded as an indispensable party in a suit to determine obligations under the disputed contract, although he may be a Rule 19(a) party to be joined if feasible.
7 Charles A. Wright et al.,
Federal Practice and Procedure
§ 1613, at 199-200 (1986) (footnotes omitted) (citing cases);
see Ferrofluidics Corp. v. Advanced Vacuum Components, Inc.,
Although the only claims before us on appeal are those alleging violation of Law 75, we note that Caguas and Oficentro are similarly dispensable parties with respect to the remaining claims. In each of the remaining claims, the defendants are alleged to be joint tortfeasors or co-conspirators and are thus jointly and severally liable. It is well-established that joint tortfeasors and co-conspirators are generally not indispensable parties.
See Goldman, Antonetti, Ferraiuoli, Axtmayer & Hetlell v. Medfit Int'l,
That Caguas and Oficentro are dispensable to this action does not, in and of itself, compel their dismissal. While the Supreme Court held in
Newman-Green
that “the courts of appeals have the authority to dismiss a dispensable nondiverse party,”
Thus, neither Casas nor Mita gained a significant tactical advantage by the presence of Caguas and Oficentro in the lawsuit. Nevertheless, we are concerned that Caguas and Oficentro could themselves face prejudice if dismissed from this suit. Caguas and Ofi-centro, while initially characterized as John Doe and Richard Roe, were contemplated as parties to this litigation from the start, and have actively participated in it since June of 1992, when they were substituted for the fictitious defendants. Had the jurisdictional defect been called to the district court’s attention at that point, the district court would have either dismissed Caguas and Oficentro from this action, thereby requiring Casas to sue them separately in the commonwealth court, or joined them to this action, thereby remanding the entire case to the commonwealth court. Either way, Caguas and Ofi-centro would have had their liability determined in a single proceeding. Instead, because of the jurisdictional oversight, dismissal of Caguas and Oficentro at this stage could subject them to a new lawsuit before a new judge in the Superior Court of Puerto Rico.
In
Newman-Green,
there was a similar difficulty. The problem there was remedied by terminating the litigation against the dismissed defendant with prejudice.
Accordingly, we dismiss Caguas and Oficentro from this action to preserve jurisdiction but direct the district court, on remand, to determine whether the injury to Caguas and Oficentro from being dismissed from this proceeding is such that their dismissal should be ordered to be with prejudice to any further suit by Casas. Caguas and Oficentro having been dismissed, complete diversity is restored per Newmanr-Green, and we retain subject matter jurisdiction over the claims between Casas and Mita.
IV.
Having disposed of the jurisdictional issues, we come to the merits of Mita’s appeal. This appeal, of course, is interlocutory, see note 6, supra, being taken solely from the granting of the injunction against Mita. But the injunction can stand only if the court properly awarded summary judgment. We accordingly confront the merits of that ruling.
On summary judgment, we review the district court’s decision
de novo. Velez-Gomez v. SMA Life Assur., Co.,
Mita’s primary argument is that genuine issues of material fact preclude the granting of summary judgment to Casas on its Law 75 claims. Specifically, Mita argues that genuine issues exist as to: (1) whether Mita impaired its contract with Casas and (2) whether Mita had “just cause” to do so. To understand these arguments, we will need to step back and take a look at the applicable law.
Law 75 protects Puerto Rico-based dealers from summary cancellation of their dealership contracts by their principal suppliers after the dealers have established a favorable market for the principal’s goods.
See Warner Lambert Co. v. Superior Court of Puerto Rico,
101 P.R.Dec. 378, 387 (1973),
translated in,
1 Official Translations 527, 541 (1973). The stated purpose of the law is to protect local dealers from abusive practices by suppliers who are financially stronger than they are.
See Medina & Medina v. Country Pride Foods, Ltd.,
88 J.T.S. 6162, 6168 (1988),
translated in,
Notwithstanding the existence in a dealer’s contract of a clause reserving to the parties the unilateral right to terminate the existing relationship, no principal or grant- or may directly or indirectly perform any act detrimental to the established relationship or refuse to renew said contract on its normal expirаtion, except for just cause.
P.R. Laws Ann. tit. 10, § 278a.
Law 75 establishes a rebuttable presumption of impairment when a supplier appoints another dealer in violation of its exclusive dealership agreement with its original dealer:
For the purposes of this Act ... it shall be presumed, but for evidence to the contrary, that a principal or grantor has impaired the existing relationship ... when the principal or grantor establishes a distribution relationship with one or more additional dealers for the area of Puerto Rico, or any part of said area in conflict with the contract existing between the parties.
P.R. Laws Ann. tit. 10, § 278a-l(b)(2). The district court adopted the magistrate’s determination that this presumption applied to Mita. Mita disputes this holding on appeal. However, Mita did not dispute impairment before the district court and, therefore, waived its right to make the argument on appeal. Even without the presumption,
*679
moreover, Casas presented ample evidence of impairment of the exclusive dealership through Mita’s appointment of Caguas and Oficentro, evidence which Mita did not dispute.
See, e.g., Draft-Line Corp. v. Hon Co.,
Law 75’s “just cause” limitation applies even where a contract includes a clause prоviding for termination under specified circumstances. Because many such termination clauses were tied to distribution quotas or goals, amendments to Law 75 in 1988 clarified what “just cause” meant in the context of contracts that contain such clauses:
The violation or nonperformance by the dealer of any provision included in the dealer’s contract fixing rules of conduct or distribution quotas or goals because it does not adjust to the realities of the Puerto Rican market at the time of the violation or nonperformance by the dealer shall not be deemed just cause. The burden of proof to show the reasonableness of the rule of conduct or of the quota or goal fixed shall rest on the principal or grantor.
P.R. Laws Ann. tit. 10, § 278a-l(c) (1988). Thus failure to meet a distribution quota will only constitute just cause for impairment under Law 75 if that quota is shown to be “reasonable” given the state of the Puerto Rican market at the time of the alleged violation.
See Newell Puerto Rico Ltd. v. Rubbermaid, Inc.,
The contract between Mita and Casas granted Casas an exclusive dealership in the greater San Juan area, so long as Casas met 85% of a specific performance quota.
11
Mita terminated the exclusive dealership when, it alleges, Casas failed to meet 85% of the quota. Under Law 75, however, Mita could not impair its contract without just cause. Under the above provisions of Law 75, Mita had “just cause” to terminate the exclusivity provision only if the quota was adjusted to the realities of the Puerto Rican market at the time of Casas’s failure to meet the quota. Moreover, Law 75 places on Mita’s shoulders the burden of proving the reasonableness of the quota. Thus, once Casas moved for summary judgment and alleged an absence of evidence showing that the quota provision was reasonable, Mita was required to come forth with such evidence in order to survive summary judgment.
Celotex,
Mita contends that it submitted evidence sufficient to raise a genuine issue of material fact as to the reasonableness of the quota. It points to letters between its counsel and Casas’s counsel, and a declaration by Masa-haru Ishidoya, vice president of Mita’s international division, describing the negotiation of the quota. Ishidoya’s declaration indicated that Casas itself requested that the exclusivity provision be conditioned upon a yearly performance goal. At his deposition, Ishido-ya indicated that the 300 copier quota in the contrаct was a negotiated reduction from a quota of 500 copiers first proposed by Mita. The 1989 contract contained express language in which Casas “acknowledges that the annual quotas ... adjust to the realities of the market” in Puerto Rico.- Ishidoya states in his declaration that he relied upon Casas’s representations to that effect. Mita also submitted a copy of the letter it sent to Casas, terminating the exclusive dealership with Ca-sas. In that letter, Mita stated it was terminating the exclusivity provision in the contract because Casas had failed to meet the quota percentages set forth in the contract.
Mita further submitted the declaration of Rafael Martinez Margarida, the Managing Partner and Partner-in-Charge of Manage *680 ment Consulting Services at Price Water-house. Mita retained Martinez as an expert witness to testify as to the reasonableness of the contract quota. In his declaration, Martinez stated that he examined Puerto. Rico’s External Trade Statistics (“PRETS”) for imports of copy machines to Puerto Rico for the period of 1985-1990. The declaration included the following table:
YEAR QTY. IMPORTED VALUE GROWTH OVER PRIOR YEAR
1985 3,054 3,427,143 N/A
1986 4,170 6,058,273 77%
1987 7,375 8,103,991 34%
1988 6,026 8,148,662 1%
1989 7,056 9,259,856 14%
1990 8,983 10,032,200 8%
Martinez noted that the value of imports increased every year between 1985 and 1990. Martinez also noted that the quota in the contract was a projection based оn Casas’s actual sales figures in 1985 (279 units), 1986 (153 units) and 1987 (230 units). Finally, Martinez noted that Casas’s sales for 1989 (80 units) and 1990 (110 units) decreased significantly, while the overall number of imports increased during that same period. Martinez concluded that the quota was reasonable given the historical trend, that Casas “failed to capitalize on the opportunities available in a growing market,” and that its failure to meet the quota “cannot be attributable to the conditions of the Puerto Rico market for photocopying machines!”
Casas points to various alleged flaws in Martinez’s methodology, and argues that these flaws require that his declaration be completely excluded as unprobative and incompetent. Casas argues that, in failing to deduct from the import figures the number of copiers exported from Puerto Rico, Martinez based his conclusions on an inaccurate picture of the internal copier market. Casas also argues that these same import figures include imports of all categories of copiers, not just the categories of copiers that Casas sold as part of its exclusive dealership agreement, and thus do not accurately reflect the precise market in which Casas was operating. 12 Casas also argues that the quota, although based on historical sales figurеs, unreasonably required Casas to double its market share in 13 months. Finally, Casas argues that Martinez failed to consider various relevant factors in his analysis, including the effect of increased intrabrand competition, changes in the number of dealers in the market, the effect of Hurricane Hugo, and the impact of the local economic recession. Accordingly, Casas argues, Martinez’s declaration must be excluded, and Mita’s remaining evidence is insufficient to raise a genuine issue of fact.
The district court found that Mita had failed to present evidence sufficient to raise a genuine issue as to the reasonableness of the quota. The court stated: *681 sas’ failure to meet the quota could not be attributed to market conditions.
*680 The magistrate found, and we agree, that the quota provision was unreasonable at the time of Casas’ nonperformance. In support of its claim that the quota was reasonable, Mita presented an unsworn 13 declaration by Rafael Martinez Margarida, a certified public accountant (CPA). In this declaration the CPA asserted that his examination of the Puerto Rico External Trade’s [sic] Statistics (PRETS) reflected a growing market for photocopying machine imports from the period of 1985 to 1990, inclusive. Thus, he concluded, Ca-
*681 As the magistrate found, Casаs proved that Mita’s argument was based on erroneous statistics. Among the factors cited by the magistrate which we find most convincing, the CPA’s report failed to take into account essential aspects of the Puerto Ri-can market such as the effects of Hurricane Hugo and the recession on the economy. The CPA’s report also failed to take into account the effect of intrabrand rivalry on Casas’s market share, a rivalry fostered by Mita’s impairment of Casas’ exclusive distributorship.
Additionally, Mita’s data as to the market for copying machines in Puerto Rico erroneously included types of copying apparatus that were not machines manufactured by Mita and sold to Casas. Thus, Mita’s evidence exaggerated the size of the market by including within it devices such as thermocopying mechanisms, which were not among those apparatuses made and sold to Casas by Mita, and minimized market conditions by failing to include negative factors such as Hurricane Hugo, the recession, the intrabrand rivalry etc. Clearly, Mita’s evidence fails to create a sufficient question to prevent the entry of summary judgment in Casas’ favor since Mita has the burden of proving that the quota’s [sic] were reasonable at the time of Casas’ nonperformance, given the legal presumption that they were not unreasonable.
Thus, it was “unreliable, lacked probative value, and does not constitute competent evidence.” [Citing Magistrate’s Report.] Mita claims now that its failure to submit more probative evidence was due to its lack of time in which to gather and present it. We find this excuse pathetic and unconvincing.
Casas,
Casas responds that the district court did not weigh Martinez’s declaration, but instead properly excluded it under Fed. R.Civ.P. 56(e)
14
. Under Rule 56(e), affidavits supporting or opposing summary judgment must set forth facts that would be admissible in evidence. A district court may exclude expert testimony where it finds that the testimony has no foundation or rests on obviously incorrect assumptions or speculative evidence.
Quinones-Pacheco v. American Airlines, Inc.,
A. Martinez’s Declaration was not Excludable
It is not clear that the district court meant to treat Martinez’s declaration as excludable under Fed.R.Civ.P. 56(e). The court nowhere articulated such a ruling. But if we assume the court meant to exclude the declaration as incompetent for summary judgment purposes, we think it went too far. We may accept that Martinez’s opinion, standing alone, was worth little more than the infer- *682 enees a fact finder might reasonably draw from the factual data stated in his declaration. Martinez was not said to have had some special familiarity with, or expertise in, the Puerto Rico copier market, apart from the data he presented and sought to interpret. However, that data, including the PRETS and Casas’s past sales figures, was admissible and, examined in a light most favorable to Mita, tends to support Martinez’s conclusion that the quota was reasonable. We see no basis under Fed.R.Civ.P. 56(e) for excluding the entire declaration altogether.
Under Rule 56(e), an affidavit must meet three requirements. It:
[1] shall be made on personal knowledge, [2] shall set forth such facts as would be admissible in evidence, and [3] shall show affirmatively that the affiant is competent to testify to the matters stated therein.
Fed.R.Civ.P. 56(e). Unless a party moves to strike an affidavit under Rule 56(e), any objections are deemed waived and a court may consider the affidavit.
See Davis v. Sears, Roebuck & Co.,
In moving below to strike the Martinez deposition under Rule 56(e), Casas made much the same arguments it now makes on appeal. Casas did not argue under the first clause in Rule 56(e) that Martinez lacked personal knowledge sufficient to testify as to the PRETS and sales figures. Nor did Ca-sas argue under the third clause that Martinez was incompetent to provide his expert interpretation of these. Rather, Casas argued, under the second clause of Rule 56(e), that the fаcts contained in the declaration were not admissible in evidence because, in essence, they were simply not sufficiently material to, and probative of, the reasonableness of the quota.
The district court characterized the declaration as containing “erroneous statistics.”
Casas,
But the increase in copier imports between 1989 and 1990, as reflected in the PRETS, implicitly rebutted Casas’s evidence that the hurricane and the local recession had had a materially adverse effect on the Puerto Rican copier market. In finding thаt the declaration failed to consider these “essential aspects” of the market, the district court overlooked the relevant inference that could be drawn from the rise in copier imports shown in the PRETS figures.
15
See Adickes v. S.H. Kress & Co.,
Casas’s argument that the PRETS and other data did not account for the impact of intrabrand competition is more troubling. See infra. While the PRETS figures suggest that the market grew in spite of the hurricane and recession, they indicate nothing directly about the possible impact of increased intrabrand competition. However, it is one thing to note this silence of the evidence, another to exclude the PRETS figures because of it. Evidence may be relevant and admissible even though, standing alone, it fails to address every issue raised in a case. As noted below, Mita presented other evidence that arguably bolsters its position that the quota was reasonable. Given the unlikelihood of ever unearthing irrefutable statistical evidence, we do not think the PRETS and other statistics, and accompanying inferences, were so weak that they should be rejected as material evidence in this case.
The district court found that the PRETS figures were also “erroneous” because they included other categories of copying machines that were not the types of machines sold by Casas.
Casas,
We conclude that the reasons set forth by the district court were insufficient bases for rеjecting the Martinez declaration altogether, assuming this was what the court intended to do. Nor do we find Casas’s additional arguments sufficient for its outright exclusion. Casas complains: that Martinez failed to deduct export figures from the import figures in order to obtain a true measure of the internal copier market; that Martinez failed to consider the fact that the quota, according to Casas, required Casas to double its market share within thirteen months; that Martinez failed to consider the fact that during the period of the contract, Casas had a smaller region of exclusive dealership than before.
While these additional arguments are not without force, a party may not exclude, on summary judgment, relevant and otherwise admissible factual evidence solely on the ground that the evidence leaves a number of unanswered questions or that it appears somewhat less persuasive than the movant’s evidence offered in rebuttal. If there are genuine issues of fact, the nonmovant is entitled to have these resolved in the trial forum, where the fact finder hears live witnesses and can better assess all the facts.
We conclude — if the district court intended to do so — that it did not have sufficient grounds for excluding Mita’s declaration under Fed.R.Civ.P. 56(e).
B. Sufficiency of Mita’s Evidence to Raise Issue of Fact
Having found no adequate basis to exclude from consideration Martinez’s declaration, we next consider whether that declaration and Mita’s other evidence were sufficient to raise a genuine issue of fact as to the reasonableness of the quota in light of the Puerto Rico market. 16 ■
*684
It is instructive first to review the summary judgment standard. “By its very terms, this standard provides that the mere existence of some alleged factual dispute between the parties will not defeat an otherwise properly supported motion for summary judgment, the requirement is that there is no
genuine
issue of
material
fact.”
Anderson v. Liberty Lobby, Inc.,
Viewing Mita’s evidence in its most favorable light, we think that, although the question is close, Mita’s evidence and the reasonable inferences therefrom are sufficient to raise a genuine issue as to the reasonableness of the quota. First, the contract executed by the parties contains a clause in which Casas expressly agreed that the quota was reasonable in light of the realities of the Puerto Rico market. We do not suggest that such a clause was binding, since public policy would presumably not permit the provisions of Law 75 to be contracted away. 17 However, we think Casas’s express agreement in the contract that the quota was reasonable is admissible evidence tending to establish the reasonableness of the quota at the time Casas signed the contract. Bolstering the weight of Casas’s concession were the letters from Mita’s attorneys and Ishidoya’s testimony showing that Casas had been successful in renegotiating the quota downward from 500 to 300 copiers. Its ability to do so suggests a degree of parity in the parties’ bargaining positions, making it more likely that Casas really believed the quota to be reasonable at the time it signed the contract. 18
In addition, inferences from the PRETS and historical sales figures contained in Martinez’s declaration suggest that if the quota was reasonable when the contract was signed, it remained so during the term of the contract. The contract required Casas to sell 255 copiers (85% of 300) during a 13-month period in order to retain its exclusive dealership. This figure was not grossly out of line with Casas’s historical 12-month sales figures: (297 in 1985, 153 in 1986, and 230 in 1987). The PRETS figures indicate that the market for copiers actually increased during the term of the contract (from 7,056 in 1989 to 8,983 in 1990). If the quota was based roughly on past sales, and if the market for *685 copiers did not suffer any decrease, it could be inferred from this evidence that the quota was reasonable in light of the Puerto Rico market.
Casas, to be sure, presented much persuasive evidence in opposition. Summary judgment, however, is not a substitute for trial. We do not think Casas’s evidence so undermined Mita’s case that Mita can be said to have failed to raise a genuine issue of fact concerning the reasonableness of the quota. At most, it indicated that many issues of fact remained to be resolved at trial. Casas presented a declaration by its president, stating that he thought the quota unreasonable and that Mita had imposed the quota unilaterally by threatening to cancel their preexisting distribution relationship. Mita’s vice president, however, asserted that he “relied on Casas’ representations that the performance goal and the related percentages were reasonable for the relevant market.” Mita’s evidence tends to suggest that the quota was arrived at through bargaining, Casas having persuaded Mita to lower the quota from 500 to 300 copiers. The Casas declaration also states that Hurricane Hugo and the local recession had an effect on the copier market. As we have previously said, however, Mita’s PRETS figures minimized these effects by showing that the copier market increased during the term of the contract.
Casas’s strongest argument is that Mita’s statistical evidence of market growth and of past sales fails to account for the fact that, prior to 1988, Casas was the only distributor of Mita products for all of Puerto Rico (even though its contract then was nonexclusive). By contrast, during the term of the contract, Casas argues, it faced stiff intrabrand competition. Its exclusive dealership covered only a portion of Puerto Rico, the greater San Juan area. While it could also sell Mita products elsewhere in Puerto Rico on a nonexclusive basis, it now faced competition from two other authorized Mita dealers outside the exclusive San Juan area as wеll as from alleged unauthorized sales of Mita’s copiers by Caguas and Oficentro. According to Ca-sas, its competitors sold 327 Mita copiers during the 13-month period of the contract. Casas argues that Mita’s past sales figures simply do not address the issue of this increased intrabrand competition, hence they say nothing as to the quota’s reasonableness during the relevant period.
But we do not think that this argument so undermines Mita’s case as to eliminate any contested factual issue. It is unclear how to assess the effects of intrabrand competition in calculating the reasonableness of the quota. The fact that other nonexclusive dealers were able to sell 327 Mita copiers during the relevant period outside of San Juan is a double-edged sword. While, to be sure, these sales suggest that Casas faced stern competition, it also indicates the existence of a strong demand for Mita copiers on which Casas was presumably free to capitalize to the extent it was capable. It is unclear, moreover, in measuring quota reasonableness, how intrabrand competition is to be distinguished from the effects of competition from copiers made by other manufacturers. Such interbrand competition would have existed earlier as well as in 1989-90. While the new factor оf intrabrand competition doubtless weakens the predictive value of Casas’s earlier sales figures, it does not totally vitiate their relevance to quota reasonableness. Ca-sas knew when it signed the contract that its exclusivity would be limited to the San Juan area, and presumably also knew of the intra-brand competition it faced elsewhere. The evidence permits an inference that in Casas’s then judgment the quota was reasonable despite the anticipated interbrand and intra-brand competition. Thereafter, the overall trend in copier imports was up suggesting— at least, as one possible interpretation of the data — that Casas’s poor performance was due not to lack of opportunity but to some fault of its own.
We conclude that Mita presented evidence sufficient to raise a genuine issue as to the reasonableness of the quota. Particularly where the standard here, “reasonableness,” is so amorphous, and “hard” evidence to prove “reasonableness” so obviously difficult to come by and subject to multiple interpretations, we are disinclined to deny Mita its day in court by raising the threshold barrier of proof too high.
See Rogen,
Throughout its brief, Casas repeatedly asserts that Mita has faded to satisfy its burden of proving that the quota is reasonable. This misapprehends the burden Mita faces at summary judgment. Mita is not required to prove that the quota was reasonable. Rather it was only required to present evidence sufficient to raise a genuine issue of fact as to reasonableness. The burden is one of producing enough evidence to show that it is entitled to a trial, not that it wdl necessarily be successful at trial.
See First Nat’l Bank of Arizona v. Cities Serv. Co.,
V.
In accordance with this opinion, we hereby dismiss Caguas and Oficentro from this suit and remand to the district court to determine whether the dismissal of Caguas and Oficen-tro should be with or without prejudice. Having determined that the district court erred in granting Casas’s motion for partial summary judgment, we vacate the court’s order granting Casas a permanent injunction. The parties’ claims will proceed in the district court consistently with this opinion. 20
So ordered. Each party shall bear its own costs.
Notes
. Paragraph 3 of Casas's complaint said:
Codefendants John Doe and Richard Roe are fictitious names used ’ to refer to defendants whose names are unknown at present. Said defendants are the natural persons and/or corporate and/or judicial entities who together with MITA have conspired, with knowledge of the contractual relationship between MITA and *671 Casas, to deprive the latter of said contractual relationship, directly and indirectly interfering therewith, causing the damages hereinafter itemized. To plaintiff s best knowledge and understanding, John Doe and Richard Roe are citizens and residents of the Commonwealth of Puerto Rico and are also liable to plaintiff pursuant to the allegations mentiоned hereinafter.
(emphasis added).
. Count Five alleged that defendants had illicitly and tortiously contracted for the distribution of Mita products in Puerto Rican territories in which Mita had granted Casas the exclusive right to distribute its products.
. In its original complaint, Casas had requested the district court to
issue a permanent injunction against Mita, ordering it [(1)] to cease and desist from continuing with the acts which constitute impairment of the terms of the distribution relationship existing between it and Casas, ... [ (2) ] to abstain from appointing, choosing, designating or arranging for other additional distributors and/or in substitution of Casasf,] and ... [ (3) ] *672 to abstain from terminating and/or altering the distribution relationship existing between both parties or performing any act or omission whatsoever in impairment thereof, all pursuant to the provisions of Law 75.
. The district court did not decide Counts Two, Four, and Five of Casas’s complaint, and, to our knowledge, they remain unresolved.
. The district court emphasized in its opinion and order that it was not placing Mita in involuntary servitude. According to the district court, Mita could impair its contractual relationship with Casas in the future if it could demonstrate just cause for doing so.
.Section 1292(a)(1) provides in relevant part:
|T]he courts of appeals shall have jurisdiction of appeals from:
(1) Interlocutory orders of the district courts of the United States ..., or of the judges thereof, granting, continuing, modifying, refusing or dissolving injunсtions, or refusing to dissolve or modify injunctions, except where a direct review may be had in the Supreme Court.
. Under 28 U.S.C. § 1367(b), for instance, federal courts, sitting in diversity, “shall not have supplemental jurisdiction ... over claims by plaintiffs against persons made parties under Rule 14, 19, 20, or 24 of the Federal Rules of Civil Procedure ... when exercising supplemental jurisdiction over such claims would be inconsistent with the jurisdictional requirements of section 1332.” This statute, which refers expressly to both compulsory and permissive join-der, "does not allow joinder of additional parties if to do so would defeat the rule of complete diversity.” Charles A. Wright, Law of Federal Courts § 9, at 38 (1994). Thus, where Congress has specifically so provided, the addition of non-diverse, dispensable parties will defeat diversity jurisdiction, even if such jurisdiction has already been established at the start of the federal proceeding.
. “[A] district court, when confronted with an amendment to add a nondiverse nonindispensable party, should use its discretion in deciding whether to allow that party to be added.”
Hensgens v. Deere & Co.,
. We agree with Casas that
International Travelers Cheque Co. v. Bankamerica Corp.,
. Mita baldly asserts that Casas could not have secured under Rule 45 the documents and infer-mation it obtained under Rules 33 and 34. Mita fails, however, to explain why this would be so.
. The quota called for Casas to sell 300 copiers and to generate $450,000 in sales of such copiers during the first 13 months of the contract, between April 1, 1989 and April 30, 1990. Thus, to preserve the exclusivity provision, Casas had to sell 255 copiers (85% of 300). If Casas fell below 255 copiers, it could still retain a nonexclusive dealership unless its sales were 50% below quota, in which event Mita could terminate any relationship whatsoever.
. Casas also argues that the yearly data was irrelevant, since Mita must provide evidence about the market on or about May 1990, when the contract was terminated. This is plainly wrong. Law 75 requires Mita to prove the reasonableness of the quota "at the time of the violation or nonperformance by the dealer.” P.R.Laws Ann. tit. 10, § 278a-l(c). Casas's alleged nonperformance occurred during the period between April 1989 and May 1990. Under the plain terms of Law 75, it is the condition of the market during that period that is relevant, not the condition of the market at the precise point of the contract's impairment by the supplier.
. The unsworn declaration was made under pain and penalties of perjury. 28 U.S.C. § 1746.
. Fed.R.Civ.P. 56(e) provides:
Supporting and opposing affidavits shall be made on personal knowledge, shall set forth such facts as would be admissible in evidence, and shall show affirmatively that the affiant is competent to testify to the matters slated therein.
Fed.R.Civ.P. 56(e).
. The cases that Casas cites in its brief,
Qui-nones-Pacheco
and
Merit Motors,
are distinguishable. In
Quinones-Pacheco,
the expert testimony with respect to damages was based on an assumption that was clearly unsupported by the record, namely that the plaintiff was permanently disabled.
. Casas does not address this issue on appeal. Casas's only argument on appeal is that the district court properly excluded the Martinez declaration. Although this could be interpreted as a *684 concession that summary judgment was improper if the Martinez declaration was admissible, we nevertheless proceed to address the key summary judgment issue.
.
Cf.
P.R. Laws Ann. tit. 31, § 3372 (1991) ("The contracting parties may make the agreement and establish the clauses and conditions which they may deem advisable, provided they arе not in contravention of laws, morals, or public order.");
In re Pagan Ayala,
. Casas argues that any evidence of reasonableness of the quota at a time prior to the period of nonperformance was irrelevant here. However, viewed in the light most favorable to Mita, we think that evidence of reasonableness immediately prior to the term of the contract was material. Combined with Martinez's declaration indicating that the Puerto Rico copier market did not subsequently decrease, but rather grew, this evidence is probative of the continuing reasonableness of the quota between April 1989 and May 1990, the relevant period. See note 12, supra.
. Without making too much of this, we note that Casas in its brief almost concedes that there exist disputed issues of fact. After listing the evidence it presented about the unreasonableness of the quota, it states: "Among others, this evidence raises material questions of fact as to the effect of Hurricane Hugo, the recession, the intrabrand competition of MITA machines, and the manipulation of statistical information by MITA's expert in order to artificially create a 'growing market’." We agree.
. We do not reach Mita’s remaining argument that, even if summary judgment was proper, the district court’s issuance of the permanent injunction was improper.
