*344Introduction
¶1 In this case1 we are asked to interpret, and ultimately overturn, a rule we established in St. Benedict's Development Co. v. St. Benedict's Hospital .2 In St. Benedict's we held that to prevail on a claim for intentional interference with contract, the plaintiff must show that the defendant interfered through "improper means."3 C.R. England, Inc. (England) argues that St. Benedict's was wrongly decided and should, therefore, be overruled.
¶2 In so arguing, England asserts that the factors for overruling precedent we established in Eldridge v. Johndrow4 -(1) the persuasiveness of the authority and (2) how firmly the precedent has become established in law-weigh in England's favor. We disagree. Because the "improper means" element has become firmly embedded in Utah law since St. Benedict's was decided, and because it remains a good rule, we decline to overturn it.
¶3 Additionally, we are asked to clarify what constitutes improper means for the purposes of a claim for intentional interference with contract. In Leigh , we explained that the element of "improper means is satisfied where the means used to interfere with a party's economic relations are contrary to law, such as violations of statutes, regulations, or recognized common-law rules," or if "they violate an established standard of a trade or profession."5 And in St. Benedict's we applied this definition of improper means to claims involving existing contracts.6 We reaffirm this definition7 and clarify that to constitute an "established standard of a trade or profession," the standard or rule must be an objective one accepted throughout the relevant industry.
Background8
¶4 England is a trucking company. As part of its business, it trains and hires individuals to work as truck drivers. To protect its investment in training individuals to work as truck drivers, England enters into employment contracts wherein the truck drivers agree to work exclusively for England for a nine-month period.9 England alleges that it has previously provided notice of these *345agreements to other trucking companies, and that it also provides notice on an ongoing basis when competing companies seek to hire England drivers who are still within the nine-month period.
¶5 Swift Transportation Company (Swift) is also a trucking company. England alleges that Swift regularly and knowingly induces England's truck drivers to breach their employment contracts with England by offering higher wages and better benefits.
¶6 In response to this activity, England filed suit against Swift, alleging that Swift intentionally interfered with England's contracts with its employees. Swift filed a motion for summary judgment against England on the ground that England failed to provide proof of "improper means"-an allegedly essential element of the tort-to support its claim.10 In its opposition, England argued that "improper means" is not an element of the tort of intentional interference with contract in Utah. Instead, it maintained that it must prove only that (1) Swift had knowledge of England's employment agreements with its truck drivers, (2) Swift recruited the drivers, (3) the drivers went to work with Swift, and (4) England suffered damages as a result, unless the "action causing the breach was done with just cause of excuse."11
¶7 Noting conflicting holdings in the federal district court of Utah regarding the elements of the tort of intentional interference with contract, the federal court requested supplemental briefing from the parties. Upon reviewing the briefing, the court concluded that there appears to be no "clear, controlling Utah law" regarding whether "improper means" is required as part of the tort. Additionally, the court concluded that if improper means is required, there is no clear law regarding what would constitute improper means.
Standard of Review
¶8 This case comes to us by certified question from the federal district court. "A certified question from the federal district court does not present us with a decision to affirm or reverse a lower court's decision; as such, traditional standards of review do not apply."12 Instead, we merely answer the question presented without resolving the underlying dispute.13 We have jurisdiction pursuant to Utah Code section 78A-3-102(1) and article VIII, section 3 of the Utah Constitution.
Analysis
¶9 This case requires us to answer two questions. First, does the tort of intentional interference with contract require proof of "improper means"? And second, if it is required, what constitutes "improper means" in the context of tortious interference with contract?
¶10 England argues that the elements of the tort of intentional interference with contract come from our opinion in Bunnell v. Bills .14 In Bunnell , we adopted the rule that "one who persuades another or conspires with another to breach a contract is guilty of an actionable tort, unless such persuasion or other action causing the breach was done with just cause of excuse."15 England argues that this should still be the law in Utah, and, to the extent subsequent cases have stated a different rule, we should overrule them under the factors for overturning precedent we articulated in Eldridge v. Johndrow .16
¶11 Swift, on the other hand, argues that our decisions in *346Leigh Furniture & Carpet Co. v. Isom17 and St. Benedict's Development Co. v. St. Benedict's Hospital18 govern. According to Swift, Leigh established a three-part test for the tort of intentional interference with economic relations, which includes interference with both existing and prospective contracts. We agree with Swift.
¶12 Although the court in Leigh did not clearly state whether its three-part test applied to the tort of intentional interference with contract, the court in St. Benedict's later interpreted Leigh as having done so.19 And following St. Benedict's , Utah courts have regularly stated that the element of "improper means" is part of the prima facie case for intentional interference with contracts.20 Because the rule established in St. Benedict's has become firmly established in Utah caselaw, and the reasoning behind it remains persuasive, we decline to overturn it.
I. We Decline to Overturn St. Benedict's and We Hold that "Improper Means" is an Element of the Tort of Intentional Interference with Contract
¶13 We first consider whether "improper means" is an element of the tort of intentional interference with contract. England argues that we should disavow any language from our decision in St. Benedict's Development Co. v. St. Benedict's Hospital21 that includes the element of "improper means" as part of the tort of intentional interference with contract. The court in St. Benedict's based its decision on language in Leigh Furniture & Carpet Co. v. Isom .22 But, according to England, the language in Leigh applied only to the related, but distinct, tort of intentional interference with prospective economic relations. For this reason, England argues that St. Benedict's interpretation of Leigh -as including the "improper means" element in the torts of intentional interference with contracts and prospective contracts-is incorrect.
¶14 Swift disagrees with England's reading of our caselaw. According to Swift, our decision in Leigh established elements for the tort of interference with economic relations, which "protects both existing contractual relationships and those not yet reduced to formal contract or not expected to be."
¶15 Although Leigh is best read as having applied only to the tort of intentional interference with prospective contracts, St. Benedict's clearly extended the Leigh test so that it applied to claims involving existing contracts as well as prospective ones. Because this resulted in a sound rule that has become firmly embedded in Utah law, we decline to overturn it.23
A. Before Leigh, the tort of intentional interference with contract required some showing of improper or unprivileged conduct by defendant
¶16 Due to the debate surrounding the development of the tort of intentional interference with economic relations, we first consider the origins of the legal theory in Utah. Specifically, it should be noted that Utah's caselaw has always held that a defendant could not be found liable for intentionally interfering with an existing contract absent proof that the interference was unexcused or unjustified. And, based on a review of the caselaw from other jurisdictions, it appears that an unexcused or unjustified interference is widely viewed as the functional equivalent *347of interference by an "improper means" or an "improper purpose."24
¶17 In Utah, the tort of intentional interference with contract has always required some proof that the alleged interference was done with some level of impropriety. In Bunnell v. Bills , the case on which England's entire argument relies, the court held that "one who persuades another or conspires with another to breach a contract is guilty of an actionable tort, unless such persuasion or other action causing the breach was done with just cause of excuse ."25 It also explained that "even though a defendant's action brings about a breach of contract, he is not liable where the breach was caused by the doing of an act which he had a legal right to do."26 The court then explained that "[w]here persons have merely pursued their own ends without any desire or intention of causing another to breach his contract, they should not be held liable for the other's breach."27 So under Bunnell , a person could be held liable for the tort of intentional interference with contract only if the person interfered in a way in which the person was not legally entitled to have interfered. Bunnell's inclusion of an "unexcused conduct" component was consistent with the approach followed in other jurisdictions at that time and since.
¶18 The court in Bunnell purported to ground its decision in "generally recognized [law] in a majority of jurisdictions."28 Because Bunnell was decided in 1962-twenty-three years after the first Restatement was published and seventeen years before the second Restatement was published, the first and second Restatements act as helpful bookends in our survey of the "generally recognized [law] in a majority of jurisdictions" at the time.29 Accordingly, we look to the Restatements of Torts, and cases in other jurisdictions that have interpreted the Restatements' language, as persuasive authority.
*348¶19 These sources suggest that the unexcused or unjustified conduct element discussed in Bunnell is synonymous with the "improper" interference element adopted in Leigh and St. Benedict's . For example, even though the first Restatement describes the tort as an interference done by "one ... without a privilege to do so"30 and the second Restatement describes it as an interference done by "[o]ne who intentionally and improperly interferes,"31 the factors provided by the first and second Restatements for determining whether an interference was actionable-i.e . lacked privilege or was improper-are substantially similar.32 So between the first and second Restatements there is no substantive difference between an unexcused interference and an improper one.33
¶20 The same is true in other jurisdictions.34 For example, in RAN Corp. v. Hudesman , the Supreme Court of Alaska noted a discrepancy in the terminology used in previous cases.35 Alaska's prima facie intentional interference with contract case required the plaintiff to prove that "the defendant's conduct was not privileged or justified."36 On the other hand, it noted that the second Restatement "speaks not in terms of 'privilege,' but requires that the actor's conduct not be 'improper,' " while "[o]ther authorities use the catch word 'malice.' "37 Ultimately, the court concluded that "[r]egardless of the phrase that is used, the critical question is what conduct is not 'privileged' or 'improper' or 'malicious.' "38 In other words, the Hudesman court concluded that even though different authorities use different terms, each authority is attempting to identify certain conduct that is improper in the context of the tort of intentional interference with contract.
¶21 As these additional authorities suggest, there is little substantive difference between requiring the plaintiff to prove that an intentional interference with a contract was without justification and requiring the plaintiff to prove that it was improper. So even though the court in Bunnell used the "without justification" terminology in describing the elements of the tort, it is clear that even under that decision some intentional interferences with a contract do not rise to the level of tortious conduct. So before a plaintiff prevails on an intentional interference with contract claim, the trial court must decide whether the interference was unexcused or improper.
*349B. It is unclear if Bunnell decided the question of whether a showing of improper conduct is part of the prima facie case or whether the lack of improper conduct is an affirmative defense
¶22 Although it is clear that Bunnell included an unexcused or improper conduct component in the tort of intentional interference with contract, this does not answer the key question in this case. This is so because it is unclear whether Bunnell placed the burden for showing that an alleged interference occurred without an excuse on the plaintiff, as part of the prima facie case, or on the defendant, as an affirmative defense. In other words, although Bunnell suggests that a defendant is not liable for intentionally interfering with a contract unless the defendant's conduct was unexcused or improper, this does not necessarily mean that "improper means" is an element of a plaintiff's prima facie case. Instead, Bunnell could be interpreted as adopting what is called the prima facie approach. Under this approach, "the plaintiff need only prove ... that the defendant intentionally interfered with his [contractual] relations and caused him injury."39 Once this is proven, "the burden ... then shifts to the defendant to demonstrate as an affirmative defense that under the circumstances his conduct, otherwise culpable, was justified and therefore privileged."40
¶23 Even though Bunnell does not clearly state who has the burden of showing that an interference was improper (or proper in the case of the defendant), dicta in Leigh suggests that Bunnell placed the burden on the defendant.41 While the court in Leigh considered which elements to include in the related tort of intentional interference with prospective economic relations, it mentioned that Bunnell had "assumed" the prima facie approach in the context of the tort of intentional interference with contract. But the Leigh court does not explain why it believed that Bunnell followed the prima facie approach, and the court in Leigh may have erred on this point.42
¶24 After stating that Bunnell assumed the prima facie approach for the tort of intentional interference with contract, the court in Leigh declined to apply the prima facie approach for the tort of interference with prospective economic relations because it "requires too little of the plaintiff."43 And after considering and rejecting a second approach to the tort,44 the Leigh court decided to adopt a third approach that had been established in Oregon.
¶25 Under this third approach, the plaintiff "must prove (1) that the defendant intentionally interfered with the plaintiff's existing or potential economic relations, (2) for an improper purpose or by improper means, (3) causing injury to the plaintiff."45 Significantly, the court announced this test as part of what it considered to be Utah's first instance of formally recognizing the "common-law cause of action for intentional interference with prospective economic relations."46 For this reason, it appears the Leigh court's standard was meant to apply only to the tort of intentional interference with prospective economic relations, and not to the already-existing tort of intentional interference with contract.
*350C. St. Benedict's interpreted Leigh as holding that a showing of improper means is part of the plaintiff's prima facie case for claims involving existing contracts as well as prospective ones
¶26 Although it appears that the court in Leigh was not attempting to alter the elements for the tort of intentional interference with contract, this court later interpreted Leigh as if it had.47 In St. Benedict's Development Co. v. St. Benedict's Hospital , we noted that Leigh was the first case to "recognize[ ] the tort of intentional interference with economic relations."48 And we explained that the "tort protects both existing contractual relationships and prospective relationships of economic advantage not yet reduced to a formal contract."49 We then announced that the three-part test first articulated in Leigh , including the improper means element, applied to situations involving existing contracts.50 So following St. Benedict's , a showing of improper means became part of the plaintiff's prima facie case for claims involving existing contracts as well as prospective ones. This rule has never been questioned by a Utah state court.
D. Under the factors established in Eldridge, we decline to overrule St. Benedict's
¶27 Because St. Benedict's clearly extended Leigh's three-part test to claims involving existing contracts, England asks us to overrule it. England argues that the court in St. Benedict's misread Leigh , and therefore the rule set out in St. Benedict's should be disavowed. Although we agree that the court in St. Benedict's misread Leigh , we do not believe-under the test for overturning precedent we established in Eldridge -that this error warrants overturning the law St. Benedict's established.
¶28 In Eldridge ,51 we established two factors to consider before overturning an earlier case: "(1) the persuasiveness of the authority and reasoning on which the precedent was originally based, and (2) how firmly the precedent has become established in the law since it was handed down." Neither of these factors weighs in favor of overturning the rule established in St. Benedict's .
¶29 First, the rule St. Benedict's established rests on a firm legal footing. Although St. Benedict's application of Leigh's three-part test to alleged interferences with existing contracts appears to have been the result of a misreading of the Leigh opinion, England fails to present a compelling reason for getting rid of it.
¶30 As our discussion of Bunnell illustrates, even before Leigh and St. Benedict's , Utah law most likely required a plaintiff to show that a defendant had interfered in an improper or inexcusable way to prevail on a claim for intentional interference with contract. So even if the St. Benedict's court erred by attributing the inclusion of the "improper means" element to Leigh , it was nevertheless correct in requiring the plaintiff to prove that the defendant had interfered with the contract through something akin to improper means.
¶31 What is more, by requiring a plaintiff to prove some form of improper, wrongful, unexcused, or unjustified conduct as part of its prima facie case, St. Benedict's merely adopted the approach followed in the vast majority of jurisdictions that recognize the tort of intentional interference with contract.52 So even if the court in St. Benedict's *351based its rule on an incorrect reading of Leigh , it nevertheless articulated a sound rule53 with which the majority of other jurisdictions agree.54
¶32 The second Eldridge factor also weighs in favor of reaffirming St. Benedict's . In determining how firmly precedent has become established in the law, we typically consider "the age of the precedent, how well it has worked in practice, its consistency with other legal principles, and the extent to which people's reliance on the precedent would create injustice or hardship if it were overturned."55 These factors support reaffirming St. Benedict's .
¶33 First, we decided St. Benedict's approximately twenty-eight years ago, and since that time, Utah appellate courts have consistently noted that "improper means" is an element of a claim for intentional interference with contract.56
¶34 For example, in Jones & Trevor Marketing, Inc. v. Lowry , the court of appeals dismissed the plaintiff's claim because of a lack of evidence of an improper means or purpose.57 In that case, the district court had granted summary judgment against the plaintiff due to insufficient evidence supporting its claim for intentional interference with contract. The court of appeals affirmed the district court because the evidence that allegedly supported the plaintiff's claim was inadmissible, and even if it were admissible, it "d[id] not demonstrate an improper purpose or means."58 Accordingly, the court of appeals applied Leigh's three-part test to a claim for interference with an existing contract and affirmed summary judgment for a lack of evidence supporting the improper means prong. So Jones (as well as the other cited cases) suggests that the element of "improper means" has been consistently applied since we decided St. Benedict's .59
*352¶35 Second, as we have already stated, the rule established in St. Benedict's is a sound one that works well in practice.60 It is clear and straightforward, and it ensures that a party will not be found liable for engaging in conduct in which the party was legally entitled to engage. For these reasons, the rule is one on which people can reasonably rely. Because the rule established in St. Benedict's has been applied consistently for twenty-eight years, and is one on which people can reasonably rely, we conclude that it has become firmly established in Utah law.
¶36 England argues, however, that St. Benedict's has not become firmly embedded in Utah law because three cases, decided after St. Benedict's , cited Bunnell without discussing St. Benedict's three-part test.61 But upon closer scrutiny, none of those cases supports England's position. For example, in Retherford , we cited Leigh and Bunnell for the proposition that to prevail on its "claim of malicious interference with contractual relations," the plaintiff had to prove that the defendant "intentionally and improperly persuaded [a contract party] to breach its implied employment contract with [the plaintiff]."62 By citing Leigh for the proposition that a claim for interference with an existing contract required proof that a defendant had "improperly" interfered with the contract, Retherford supports, rather than contradicts, St. Benedict's reading of Leigh . And the same is true of the other two cases England cites.63
¶37 England also argues that St. Benedict's is not firmly embedded because "in subsequent years ... courts applying Utah law have adopted various approaches to the relationship between the two interference torts." But England is able to cite only federal district court cases for this proposition. And, once again, those cases do not stand for what England claims they do. For example, only one of the cases England cites stands for the assertion that "a claim of tortious interference with contract does not require proof of improper means."64 But that assertion is based solely on a Tenth Circuit case that was decided five years before our decision in St. Benedict's .65
¶38 The other cases England cites provide even less support for its position. Although the cases appear to make some distinction between the tort of intentional interference with contract and the tort of intentional interference with prospective contracts rather than using the umbrella term "intentional interference with economic relations," each of the cases nevertheless requires a defendant to have interfered "improperly" before liability for interference with a contract is found.66
*353So even in the instances where federal courts did not adopt St. Benedict's formula verbatim, they have required plaintiffs to plead and to prove something roughly equivalent to "improper means."
¶39 Because the weight of authority supports St. Benedict's adoption of the "improper means" element for the tort of intentional interference with contract, and because this element has become firmly embedded in Utah law, we reaffirm it.67
II. We Hold that "Improper Means" Requires Proof that an Action was Contrary to a Statute, Regulation, Common Law Rule, or an Established Standard of a Trade or Profession
¶40 Next, we must determine what constitutes "improper means." England argues that inducement of a breach of an existing contract constitutes improper means. Swift, on the other hand, argues that improper means is conduct "contrary to law, such as violations of statutes, regulations, ... recognized common-law rules" or "the violation of an established standard of a trade or profession." We agree with Swift.
¶41 Since Bunnell v. Bills , we have recognized that a defendant should not be liable for interfering with a contract where the interference was caused by the defendant's "doing of an act which he had a legal right to do."68 In Leigh Furniture & Carpet Co. v. Isom69 and St. Benedict's Development Co. v. St. Benedict's Hospital ,70 we followed this principle by including the element of "improper means" as part of a claim for tortious interference with economic relations-either with existing contracts or merely prospective economic relationships. In Leigh we acknowledged that "[i]n the rough and tumble of the marketplace, competitors inevitably damage one another in the struggle for personal advantage," but we explained that "[t]he law offers no remedy for those damages-even if intentional-because they are an inevitable byproduct of competition."71 For this reason, it was necessary to limit the scope of actionable conduct, by including an improper purpose or means element, to conduct in which the defendant did not have a recognized legal right to engage.
¶42 In doing so, we defined improper means narrowly to include only those actions that "are contrary to law, such as violations of statutes, regulations, or recognized common-law rules," or actions that violate "an established standard of a trade or profession."72 After defining improper means in this way, the court in Leigh provided a non-exhaustive list of conduct that would constitute improper means: "violence, threats or other intimidation, deceit or misrepresentation, bribery, unfounded litigation, defamation, or disparaging falsehood[s]."73 And we noted that because "[s]uch acts are illegal or tortious in themselves" they "are clearly 'improper' means of interferences."74
*354¶43 When we expanded the Leigh test to apply to interference with existing contracts in St. Benedict's , we also adopted the Leigh standard for what constitutes improper means.75 Following our decision in St. Benedict's , courts have consistently interpreted the "improper means" element in accordance with the definition outlined in Leigh and St. Benedict's .76
¶44 More recently, in Eldridge v. Johndrow ,77 we emphasized once again that a person is not liable for intentional interference where the person engaged only in conduct in which he or she was legally entitled to engage. In that case we disavowed the "improper purpose" prong that had previously been part of the Leigh standard because it "allow[ed] juries to find even the most commonplace commercial conduct tortious."78 We noted that this was problematic because "such a tort would interfere with 'much competitive commercial activity, such as a businessman's efforts to forestall a competitor in order to further his own long-range economic interests.' "79 So by eliminating the improper purpose prong, Eldridge furthered our expressed goal of limiting the scope of actionable conduct to that conduct in which the defendant did not have a legally recognized right to engage.80
¶45 Accordingly, from Bunnell to Eldridge , we have been careful to limit the scope of actionable conduct within the tortious interference context to those situations where a defendant employs a means that is independently tortious or wrongful.81 We see no reason to depart from this approach.
¶46 As a final note, Swift asks us to clarify what would constitute a violation of an established standard of a trade or profession. Specifically, Swift argues that our standard is the equivalent of the standard adopted in California, which specifies that only violations of rules or standards that "provide for, or give rise to, a sanction or means of enforcement for a violation " should suffice for improper means.82 But California's standard is more limited than any standard ever applied in a Utah appellate court. Instead, Utah appellate courts typically require only that the industry standard or rule "be an external and *355objective one, rather than the individual judgment, good or bad, of the particular actor."83
¶47 For example, in Walker v. Anderson-Oliver Title Insurance Agency, Inc., the court of appeals affirmed summary judgment against a plaintiff's tortious interference claim because "the evidence [the plaintiff] offer[ed] [was] legally insufficient to establish a title insurance industry standard," and, therefore, the plaintiff could not prove improper means.84 In doing so, the court explained that "[e]stablishing an industry standard requires more than evidence of a particular company's rules and policies."85 Instead, the court explained that the plaintiff needed to provide evidence "to establish the existence of an industry-wide standard."86 This could be done, according to the court, in the same way an industry standard is established in the negligence context.87 We adopt Walker's approach to this issue.
¶48 In sum, we reaffirm our definition for improper means as conduct contrary to law-such as violations of statutes, regulations, or recognized common-law rules-or the violation of an established standard of a trade or profession.88 Additionally, in regards to established standard of a trade or profession, we adopt the approach followed in Walker, and hold that the violation of an objective, industry-wide standard or rule may constitute improper means. And under the Walker approach, the existence of an objective, industry-wide standard may be established in the same way it is established in the negligence context (through expert testimony regarding industry-wide customs or practices, uniform codes, industry-specific regulations, etc.).
Conclusion
¶49 Because the element of improper means is firmly established in Utah law, and rests upon a firm legal footing, we decline to overturn St. Benedict's Development Co. v. St. Benedict's Hospital.89 We also reaffirm the definition of improper means provided in Leigh Furniture & Carpet Co. v. Isom90 and St. Benedict's . And we clarify that to prove the element of improper means based on an alleged violation of an established industry rule or standard, the plaintiff must provide evidence of an objective , industry-wide standard.
This case comes to us as a certified question from the Federal District Court, District of Utah.
811 P.2d 194 (Utah 1991).
The court in St. Benedict's actually held that the plaintiff must show that the defendant interfered through improper means or with an improper purpose , but our decision in Eldridge v. Johndrow subsequently eliminated the improper purpose prong. 2015 UT 21, ¶ 14, 345 P.3d 553. For this reason, we do not refer to the improper purpose prong when discussing St. Benedict's or Leigh Furniture & Carpet Co. v. Isom , 657 P.2d 293 (Utah 1982), the case upon which our decision in St. Benedict's relied.

We note, however, that we have defined improper means by referring to a non-exhaustive list. In other words, by reaffirming the language in Leigh we are not suggesting that the improper means prong of the tort could not be satisfied by improper conduct that does not fit squarely in one of the categories set out in Leigh .

Swift argues that the elements of the tort of intentional interference with contract are found in St. Benedict's Development Co. v. St. Benedict's Hospital , 811 P.2d 194 (Utah 1991). Under St. Benedict's , the elements of the tort are "(1) that the defendant intentionally interfered with the plaintiff's existing or potential economic relations (2) ... by improper means, (3) causing injury to the plaintiff."

We also note that it is possible that "improper means" would be part of Utah law even in St. Benedict's absence. This is so because dicta in Leigh , which stated that under previous cases something equivalent to a lack of improper conduct was an affirmative defense rather than part of the plaintiff's prima facie case, appears to have incorrectly stated the law in Utah. In other words, the cases decided before Leigh also arguably required some showing of improper conduct as part of the plaintiff's prima facie intentional interference with contract claim.
See Elgin v. Montgomery Cty. Farm Bureau , 549 So.2d 486, 488-89 (Ala. 1989) (explaining that the plaintiff could not prove lack of justification because the insurance company acted pursuant to its contractual right); Waldroup v. Lindman , 28 P.3d 293, 296-97 (Alaska 2001) (holding that the plaintiff had to show that the defendant's actions were motivated by spite rather than economic interest to fulfill "lack of justification" requirement); Wells Fargo Bank v. Ariz. Laborers, Teamsters & Cement Masons Local No. 395 Pension Tr. Fund , 201 Ariz. 474, 38 P.3d 12, 31-32 (2002) (stating that the most important factors in the improper conduct test are the nature of the conduct and the motive). A statement in Leigh clearly shows that a lack of justification is the equivalent to "improper means" or "improper purpose." See Leigh , 657 P.2d at 305. In Leigh , the jury instructions only required the jury to find that the defendant's action was "[w]ithout justification." Id. Although the court in Leigh determined that improper means or purpose must be found, it affirmed the jury's finding of liability because "[u]nder the trial court's definition of 'justification,' the jury had to find that the Corporation's conduct was 'wrongful or malicious' before they could find for [the plaintiff]," and according to the court "[t]hose terms are functionally equivalent to 'improper means or improper purpose.' " Id.
Additionally, we note that many of the cases we cite in this opinion refer to "spite," "motive," or some other analog to the element of "improper purpose." Although the "improper purpose" prong is no longer part of the tort in Utah, see generally Eldridge v. Johndrow, 2015 UT 21, 345 P.3d 553, we nevertheless rely on these cases for the proposition that those courts require some level of impropriety, even where the operative language in their caselaw calls for a showing of a lack of justification or excuse. In citing these cases we in no way suggest that proof of an improper purpose is an element of the tort in Utah.

Federated Milk Producers Ass'n , which states that "there is no liability for procuring a breach of contract where the breach is caused by the exercise of an absolute right-that is, an act which a person has a definite legal right to do without any qualification." 360 P.2d 1018, 1022 (Utah 1961). And Gammon , in turn, cites the American Law Reports, which states that "a party to a contract, whether of employment or otherwise, has a right of action against a person who has procured a breach of such contract by the other party thereto otherwise than in the legitimate exercise of his own rights " and "it is universally recognized that an action will lie for inducing breach of contract by resort to means in themselves unlawful ."

Restatement (First) of Torts § 766 ( Am. Law Inst. 1939).
Restatement (Second) of Torts § 766 ( Am. Law Inst. 1979).
For example, the first Restatement lists five factors for determining whether an interference lacked privilege: "(a) the nature of the actor's conduct, (b) the nature of the expectancy with which his conduct interferes, (c) the relations between the parties, (d) the interest sought to be advanced by the actor and (e) the social interests in protecting the expectancy on the one hand and the actor's freedom of action on the other hand." Restatement (First) of Torts § 767 ( Am. Law Inst. 1939). And the second Restatement lists all of the same factors for determining whether an interference is improper. Restatement (Second) of Torts § 767 ( Am. Law Inst. 1979). The second Restatement also adds two other factors: "the actor's motive" and "the proximity or remoteness of the actor's conduct to the interference." Id.
Importantly, neither Restatement describes who has the burden of proving, or disproving, the wrongful nature of the interference.

Co. , 109 Ill.App.3d 596, 65 Ill.Dec. 143, 440 N.E.2d 998, 1007-08 (1982) (explaining that the element of "intentional and malicious inducement" is the equivalent of without justification or privilege), abrogated on other grounds by McInerney v.

The Leigh court's reading of Bunnell could be based on an assumption that when the court in Bunnell used the term "justification," it was referring to an affirmative defense. Although it is true that "justification" is typically a term used to describe an affirmative defense, this does not seem to be the case when it is used in the context of the tort of intentional interference with contract. See, e.g., RAN Corp. , 823 P.2d at 648 (explaining that Alaska's prima facie intentional interference with contract case required the plaintiff to prove that "the defendant's conduct was not privileged or justified" (citation omitted) ). So it appears that the dicta in Leigh was based on an incorrect assumption regarding the "lack of justification" component of the tort.
Leigh , 657 P.2d at 303.
The court considered the second Restatement approach, which requires the court to consider several factors before deciding whether the defendant's conduct was "improper." See id. at 303-04.

The rule is sound because it furthers the principle first articulated in Bunnell , and reiterated in Leigh and Eldridge , that a defendant should not be held liable for conduct in which the defendant had a legal right to engage. See Bunnell , 368 P.2d at 602 (explaining that a defendant "is not liable where the breach was caused by the doing of an act which he had a legal right to do"); Leigh , 657 P.2d at 307 (explaining that "[t]he law offers no remedy for" the "inevitabl[e] damage" one competitor causes another "[i]n the rough and tumble of the market place"); Eldridge , 2015 UT 21, ¶ 50, 345 P.3d 553 (disavowing the improper purpose prong of Leigh because it "allow[ed] juries to find even the most commonplace commercial conduct tortious").
We are not bound, of course, by the rules established in other jurisdictions. But the fact that our approach is consistent with the approach followed by a majority of jurisdictions is evidence that we have adopted a rule that works well in practice.

As further evidence that St. Benedict's has been consistently applied, we note that Utah's model jury instruction includes "improper means" as an element for the tort of intentional interference with economic relations, which encompasses claims for interference with existing contracts as well as prospective ones. See Model Utah Jury Instruction 2d CV 1401. Although we do not review our model jury instructions for correctness, and have noted that they may not correctly state the law in Utah, see Jones v. Cyprus Plateau Mining Corp ., 944 P.2d 357, 359 (Utah 1997) (explaining that the model jury instructions "are merely advisory and do not necessarily represent correct statements of Utah law"), the inclusion of the "improper means" element in the model instructions suggests that Utah's district courts regularly apply the "improper means" element to claims involving existing contracts, and that people generally have begun to rely on the rule.

Throughout its brief, England argues that we must eliminate the improper means element for claims involving existing contracts in order to distinguish between interferences with existing contracts and interferences with prospective contracts. But we do not believe that this is necessary, because the nature of a contract already provides such a distinction. This is so for three reasons. First, the existence of a prospective contract will be much more difficult to prove than the existence of an existing contract. Second, causation and damages will also be more difficult to prove for an alleged prospective contract than they will for an existing contract. And third, improper means will be easier to prove with existing contracts than with merely prospective contracts because of the greater protection laws, regulations, and customs provide for existing contracts.

Id. As a result of our decision in Eldridge , a plaintiff must prove that a defendant interfered by using improper means-proof of an improper purpose is no longer sufficient.

To be clear, under our improper means standard the conduct need not constitute illegal conduct under a criminal statute. Instead, it need only be contrary to law in a general sense, such as a violation of a statute, regulation, recognized common-law rule, or an established standard of a trade or profession.
