*344Introduction
¶1 In this case
¶2 In so arguing, England asserts that the factors for overruling precedent we established in Eldridge v. Johndrow
¶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."
Background
¶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.
¶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.
¶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."
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 .
¶11 Swift, on the other hand, argues that our decisions in *346Leigh Furniture & Carpet Co. v. Isom
¶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.
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 Hospital
¶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.
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."
¶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 ."
¶18 The court in Bunnell purported to ground its decision in "generally recognized [law] in a majority of jurisdictions."
*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"
¶20 The same is true in other jurisdictions.
¶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."
¶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.
¶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."
¶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."
*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.
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 ,
¶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.
¶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."
¶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.
¶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.
*352¶35 Second, as we have already stated, the rule established in St. Benedict's is a sound one that works well in practice.
¶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.
¶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."
¶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.
*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.
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."
¶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."
*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.
¶44 More recently, in Eldridge v. Johndrow ,
¶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.
¶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.
¶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.
¶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.
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.
This case comes to us as a certified question from the Federal District Court, District of Utah.
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.
Leigh ,
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 .

See Eldridge ,
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 ,
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,
Id. at 603. In support, the court in Bunnell cites Gammon v. 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."

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."
Importantly, neither Restatement describes who has the burden of proving, or disproving, the wrongful nature of the interference.
See, e.g. , WaveDivision Holdings, LLC v. Highland Capital Mgmt., L.P. ,
Leigh ,
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. ,
Leigh ,
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
St. Benedict's ,
Ventas, Inc. v. Health Care Prop. Inv'rs, Inc. ,
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 ,
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 .,

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.

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.
