COFFIN, Senior Circuit Judge.

A Maine company, Auto Europe, LLC, brought this diversity action against Connecticut Indemnity Company ("CI"), seeking a declaratory judgment that the insurance company has a duty to defend Auto Europe in a pending consumer fraud suit. The district court, over CI's objection, concluded that Maine is the proper venue for the coverage dispute, Maine substantive law governs it, and CI has a duty to defend Auto Europe. After careful review of the law and the record, we conclude that CI's challenges to those determinations are unavailing. We also affirm the district court's award of attorney's fees against the insurer.

I. Background

Auto Europe is a defendant in a lawsuit ("the Harter action") filed in June 2001 by four Illinois residents who claim that the Maine company and two other travel businesses "deceptively concealed" an "add-on" to their charges for foreign car rentals. The Harter plaintiffs contend that the defendants calculated foreign sales tax on a car rental base price that included a nontaxable broker's fee, effectively increasing the brokers' fees in the guise of a charge they claimed was a foreign tax. The complaint alleged that the price information given to consumers was "designed to mislead and conceal" the nature of the additional charge, and it accused the defendants of engaging in a "fraudulent scheme of overcharges." The complaint alleged various violations of federal and state law, including both the Maine and Illinois consumer fraud acts.

CI coincidentally insured all three Harter defendants under separate policies, each of which provided the same coverage. Auto Europe's policy promises payment for all sums that the insured becomes obligated to pay because of "any negligent act, error or omission of the 'insured' . . . in the conduct of 'travel agency operations' by the 'named insured.'" The policy excludes coverage, however, for "liability arising out of any act, error or omission which is wilfully dishonest, fraudulent or malicious, or in wilful violation of any penal or criminal statute or ordinances, and is committed (or omitted) by or with the knowledge or consent of the 'insured.'"

Based on the exclusion, CI refused to defend Auto Europe in the Harter action, and Auto Europe thereafter filed this suit. CI filed a counterclaim in the Maine litigation, seeking a declaratory judgment that it had no duty to defend, and it filed suit in Illinois against all three Harter defendants, seeking that same relief. It also filed a motion in Maine to transfer venue of Auto Europe's action to Illinois.

The magistrate judge in Maine denied the transfer motion, determined that Maine law applied to the action, and concluded that CI had a duty to defend Auto Europe. The district court, after a de novo review that included oral argument, affirmed the decision denying transfer of venue and adopted the magistrate judge's recommendation that summary judgment be granted for Auto Europe on the duty to defend. Under Maine law authorizing an award of attorney's fees to an insured when the insurer's duty to defend was "clear," the district court awarded reasonable fees and costs to Auto Europe.

Subsequently, the district court in Illinois also ruled, in the lawsuit filed by CI, that the insurer had a duty to defend in the Harter action. That ruling, applying Illinois law, was not directly applicable to Auto Europe, however, because the Maine company had been dismissed from the Illinois proceedings.

In its appeal of the Maine decision, CI argues that the district court, as reflected in the decisions of both the magistrate judge and district judge, erred on the procedural issues of venue and choice of law as well as in finding a duty to defend under Maine law. The insurer further objects to the imposition of attorney's fees and costs. We address each issue in turn.

II. The Motion to Transfer Venue

The propriety of the venue ruling warrants little discussion. The magistrate judge fully considered and discussed CI's motion and its judgment, particularly when affirmed by the district court, is entitled to considerable deference. See Osband v. Woodford, 290 F.3d 1036, 1041 (9th Cir. 2002) (noting that magistrate judge's pretrial order is reversible by the district court, under 28 U.S.C. § 636(b)(1)(A), only if it is "'clearly erroneous or contrary to law,'" and that same standard applies to appellate review); Phinney v. Wentworth Douglas Hosp., 199 F.3d 1, 4 (lst Cir. 1999) (same); see also Coady v. Ashcraft Gerel, 223 F.3d 1, 11 (lst Cir. 2000) (appellate standard of review for venue motion is abuse of discretion).

Although it may have been more efficient to determine CI's duty to defend with respect to all three Harter defendants in the same forum, we do not agree that the district court was obliged to transfer the case to Illinois. Its reasons for declining to do so were sound and appropriate, focusing on the weight accorded to plaintiff's choice of the forum in which it is located, the unlikelihood of any witness inconvenience because of the probability of a document-based determination of the duty to defend, and the absence of any compelling reason related to judicial economy. We therefore find no error in the court's denial of the transfer motion.

III. Choice of Law

CI next challenges the district court's decision to apply Maine law to the coverage dispute. A federal court sitting in diversity jurisdiction must employ the choice-of-law principles of the forum state, Klaxon Co. v. Stentor Elec. Mfg. Co., 313 U.S. 487, 491, 61 S.Ct. 1020, 85 L.Ed. 1477 (1941); Crellin Techs., Inc. v. Equipmentlease Corp., 18 F.3d 1, 4 (lst Cir. 1994), and the district court's choice of law pursuant to the state framework is reviewed de novo, Crellin Techs., 18 F.3d at 4.

Under Maine law, when an insurance contract does not specify the jurisdiction that should govern disputes arising under it,

the rights and duties of the parties . . . are to be determined at the forum level by the local law of the state which, with respect to that particular issue, has the most significant relationship to the transaction and the parties. Specifically, in a casualty insurance contract . . . the validity of the contract and the rights and duties created thereby, are to be determined . . . by the local law of the state which the parties understood was to be the principal location of the insured risk during the term of the policy, unless with respect to the particular issue involved, some state has a more significant relationship to the transaction and the parties. . . . Baybutt Constr. Corp. v. Commercial Union Ins. Co., 455 A.2d 914, 918 (Me. 1983), overruled on other grounds, Peerless Ins. Co. v. Brennon, 564 A.2d 383 (Me. 1989) (adopting Restatement (Second) of the Law, Conflict of Laws 2d (1971) [hereinafter "Restatement"], §§ 188, 193).

As with the venue ruling, the magistrate judge offered a thoughtful assessment of the choice of law question. Noting that the underlying complaint purported to assert the claims of a nationwide class against Auto Europe, he rejected the relevance of the location of the named plaintiffs' individual transactions because "an unknown number of plaintiffs in an unknown number of locations may have claims that fit within the purported class." He also noted that the complaint alleged that Auto Europe's principal place of business was in Portland, Maine, and because no other business location is identified, "[b]y terms of the complaint Auto Europe could only have acted in Maine." Recommended Decision at 7. The magistrate judge thus viewed Maine as "the principal location of the insured risk," and ruled that, under Baybutt, Maine law should apply.

CI contends that the law of either Florida or Illinois would be more appropriate than Maine law because both "would appear to have more significant interests in this coverage litigation and greater contacts with the transactions underlying the dispute than does Maine." According to CI, Florida is significant because the contract that provides the insurance coverage at issue in this case was negotiated and delivered there to Auto Europe's corporate parent. The policy insured more than two dozen affiliates or subsidiaries in a variety of locations, and Auto Europe apparently was the only one located in Maine. CI also cites Illinois' central importance to this case as the home state of the named plaintiffs in the Harter litigation. The two plaintiffs who did business with Auto Europe booked their rental cars through local travel agents in Chicago, and Illinois is also where the underlying lawsuit is pending.

We can easily eliminate the law of Florida as more appropriate than Maine law for resolving the coverage issue. Our reading of the authorities indicates that a policy covering numerous related companies located in different states would be deemed a multiple risk policy that, for Maine choice of law purposes, would be viewed in a particular case as if a separate policy had been issued to cover each entity. See Baybutt, 455 A.2d at 919; Restatement, § 193, comment f. Because Florida's status stems only from its role with respect to the overall policy, its significance in this case thus drops away, and the question becomes whether Maine — Auto Europe's principal location — should provide the substantive legal principles, or whether, "with respect to the particular issue involved, [Illinois] has a more significant relationship to the transaction and the parties," Baybutt, 455 A.2d at 918.

We think the district court got it right. Auto Europe, a Maine business with offices only in Maine, is alleged to have committed consumer fraud by its conduct in Maine. Although the named plaintiffs live in Illinois, and presumably for that reason found it convenient to file their lawsuit there, Illinois cannot be said to have a more significant relationship to the parties and transaction than does Maine. To be sure, the plaintiffs' home state has a substantial interest in ensuring that its citizens are not defrauded by out-of-state companies operating through local agents. Under Maine's choice of law principles, however, its own substantial interests take precedence because, as Auto Europe's home base, Maine is "the principal location of the insured risk." The district court therefore correctly ruled that Maine law governs the coverage dispute.

IV. Duty to Defend

Under Maine law, the duty to defend is determined by means of the comparison test: the complaint in the underlying lawsuit is compared with the insurance policy to ascertain if "'there exists any legal or factual basis which could be developed at trial which would obligate the insurers to pay under the policy.'" United Bank v. Chicago Title Ins. Co., 168 F.3d 37, 39 (lst Cir. 1999) (quoting NE Props., Inc. v. Chicago Title Ins. Co., 660 A.2d 926, 927 (Me. 1995)); see also Me. Mut. Fire Ins. Co. v. Gervais, 715 A.2d 938, 940 (Me. 1998).

If the complaint shows even a possibility that the events giving rise to it are within the policy coverage, the insurer must defend the suit. Any ambiguity must be resolved in favor of a duty to defend.

Mass. Bay Ins. Co. v. Ferraiolo Constr. Co., 584 A.2d 608, 609 (Me. 1990); see also York Ins. Group of Maine v. Lambert, 740 A.2d 984, 985 (Me. 1999).

The magistrate judge, affirmed by the district court, found a duty to defend based on the possibility that the proof at trial would establish a non-intentional violation of the Maine Unfair Trade Practices Act (UTPA), Me. Rev. St. Ann. tit. 5, §§ 205-A-214 (West 2002). CI contends that the district court erred because the Harter complaint alleges only intentional fraud, bringing it within the policy exclusion for willfully dishonest or fraudulent acts. CI cites caselaw from Illinois and Florida for the proposition that coverage is unavailable under exclusions similar to the one here when the complaint is limited to allegations of intentional conduct, even if the facts would have permitted recovery based on theories not covered by the exclusion. See, e.g., Fed. Ins. Co. v. Applestein, 377 So.2d 229, 231 (Fla.App. 1979) (holding that, notwithstanding policy coverage for libel and slander generally, allegations that comments were made "'with malice'" and "in a specific 'attempt to discredit'" the underlying plaintiff "completely negate coverage by conclusively establishing that the exclusion applies"); United Fire Cas. Co. v. Jim Maloof Realty, Inc., 105 Ill.App.3d 1048, 61 Ill.Dec. 799, 435 N.E.2d 496, 498-99 (1982) ("[S]ince the factual allegations of the complaint are premised upon only one theory of recovery, that of intentional fraud, and do not fall within the potential coverage of the insurance policy, United has no duty to defend its insureds."). CI argues that the Maine comparison test requires the same result, although it notes that no Maine cases have explicitly addressed the circumstance of a complaint alleging only intentional conduct where recovery based on less-than-intentional conduct also could have been sought.

Although we doubt that CI could prevail even under the law of Florida or Illinois where, as here, the relevant cause of action does not require intentional conduct for recovery, we are certain that, under Maine law, CI's argument is without merit. We simply note, in passing, that some of the cases relied upon by CI are distinguishable because they involved either underlying causes of action limited to intentional conduct, see, e.g., Ill. Farmers Ins. Co. v. Preston, 153 Ill.App.3d 644, 106 Ill.Dec. 552, 505 N.E.2d 1343, 1347 (1987) (noting that the claim assertedly within the policy's coverage was based on 42 U.S.C. § 1983, which offers "no remedy . . . based upon the mere negligence of the defendant"); Jim Maloof Realty, Inc., 61 Ill. Dec. 799, 435 N.E.2d at 498-99 (observing that underlying complaint "essentially states one cause of action, that of intentional fraud"), or factual situations that foreclosed the possibility of unintentional conduct, see, e.g., Rubloff, Inc. v. Am. Nat'l Fire Ins. Co., 1997 WL 264327, at *6 (N.D.Ill.) ("negligent conduct is not even a theoretical possibility under [the] complaint"). In other words, in these cases, the theory of relief chosen by the underlying plaintiff depended upon a showing of deliberate conduct, placing any possible recovery outside the policy's coverage, and leaving the insurer with no duty to defend.

Here, by contrast, not only does the cause of action at issue — the Maine UTPA — permit liability in the absence of an intent to deceive, but Maine law also broadly extends the duty to defend to claims that could be developed either legally or factually at trial so as to fall within the policy's coverage. Like the district court, we think it certainly possible in this case that the facts as developed at trial would reveal an improper practice that was unaccompanied by an intent to deceive. Thus, even if a jury rejected the Harter plaintiffs' precise theory of deliberate misrepresentation, they would retain the possibility of recovery under the UTPA. CI consequently is obliged to defend the Harter lawsuit. See, e.g., Me. Mut. Fire Ins. Co., 715 A.2d at 942 ("[B]ecause [the underlying defendant] may be found to have intentionally inflicted emotional distress without subjectively intending or foreseeing the alleged distress suffered by [the plaintiff], the exclusion for intended or expected bodily injury is inapplicable.").

In sum, when the cause of action alleged as the basis for liability does not include elements that would foreclose coverage, and where the events giving rise to the complaint may be shown at trial to fall within the policy's coverage, Maine law entitles the insured to a defense. See id. Indeed, we suspect that Maine's inclusive approach to the duty to defend is designed precisely for circumstances such as these — where a narrow reading of the complaint's factual allegations might preclude coverage, but the alleged cause of action is sufficiently broad that a modified version of the facts could be developed at trial to show liability.

The district court therefore properly ruled that CI has a duty to defend the Harter lawsuit.

V. Attorney's Fees

Auto Europe sought reimbursement of the attorney's fees incurred in pursuing this declaratory judgment action, and following the district court's grant of that request, the parties stipulated to the amount of $42,675.91. Maine law authorizes an award of attorney's fees against an insurer when its "duty to defend is clear from the policy and the pleadings," Maine Mut. Fire Ins. Co. v. Gervais, 745 A.2d 360, 362 (1999) (internal citation omitted).

To determine whether a duty to defend is "clear" for purposes of awarding attorney fees, a court must evaluate state law regarding an insurer's duty to defend as it existed at the time the insurer initiated the declaratory judgment action.

Id. Our review of the district court's decision is de novo. Id.

Without elaborating, the district court concluded that Auto Europe was entitled to fees "because the duty to defend was and is clear." We agree with that conclusion. Although CI might legitimately have entertained some doubts about whether the comparison test inevitably required a defense in all three relevant jurisdictions, the case law in each is unequivocal in directing that any lack of clarity must be resolved in favor of the insured. See Ferraiolo Const. Co., 584 A.2d at 609 ("Any ambiguity must be resolved in favor of a duty to defend.") (Maine law); Wilkin Insulation Co., 161 Ill.Dec. 280, 578 N.E.2d at 930 ("All doubts and ambiguities must be resolved in favor of the insured.") (Illinois law); Lime Tree Vill. Cmty. Club Ass'n, 980 F.2d at 1405 ("If the allegations of the complaint leave any doubt as to the duty to defend, the question must be resolved in favor of the insured.") (Florida law). Regardless of which of the three state's laws applied, the potential for coverage existed at the time CI refused to defend Auto Europe. The duty to defend was therefore "clear" and, accordingly, the district court properly awarded attorney's fees.

VI. Conclusion

The district court properly concluded that this insurance coverage dispute should be heard in Maine and resolved pursuant to Maine law. Because CI's duty to defend was clear, the district court properly awarded attorney's fees to Auto Europe.

The judgment of the district court is therefore affirmed.
