Thomas Rael appeals the district court’s dismissal of his state law tort claims 

as preempted by § 301 of the Labor Management Relations Act (“LMRA”), 

29 U.S.C. § 185(a). Exercising jurisdiction under 28 U.S.C. § 1291, we affirm.

 After examining the briefs and appellate record, this panel has determined 

unanimously to honor the parties’ request for a decision on the briefs without oral 

argument. See Fed. R. App. P. 34(f); 10th Cir. R. 34.1(G). The case is therefore 

submitted without oral argument. This order and judgment is not binding precedent, 

except under the doctrines of law of the case, res judicata, and collateral estoppel. It 

may be cited, however, for its persuasive value consistent with Fed. R. App. P. 32.1

I. Factual Background 

Rael worked for Smith’s Food and Drug Centers as a meat cutter for 25 years 

until he resigned in December 2014. The terms of Rael’s employment were governed 

by a collective bargaining agreement (“CBA”) negotiated between Smith’s and 

Rael’s union. Arturo Suazo became Rael’s immediate supervisor approximately a 

year before he resigned. 

In his operative complaint, Rael alleged that he left his position with Smith’s 

because of continual harassment by Suazo. He claimed that Suazo frequently yelled 

at and “constantly harassed, belittled, and degraded” him. Aplt. App. at 20. More 

specifically, Suazo repeatedly called Rael “old man,” regularly said he “was moving 

too slow,” and told Rael that younger meat cutters could do his job better and get it 

done faster. Id. Rael claimed that, due to a workplace injury, he was unable to work 

as fast as younger employees or as quickly as Suazo demanded. He alleged that he is 

58 years old, while Suazo is “much younger.” Id. 

Rael complained about Suazo’s harassment and mistreatment to several 

assistant store directors and to the local head of human resources for Smith’s. These 

individuals said they would talk to Suazo, but Suazo never modified his conduct. He 

instead told Rael that he could find another job if he did not like the way Suazo 

treated him. Rael ultimately resigned due to “constant pressure” from Suazo, feeling 

that he had been “constructively terminated.” Id. at 21. Rael alleged that Suazo was 

acting within the course and scope of his employment at all material times. 
3 

Rael alleged state law claims for intentional infliction of emotional distress 

(“IIED”) and prima facie tort against both Smith’s and Suazo. Defendants moved to 

dismiss the complaint, arguing that Rael’s claims are preempted by § 301 of the 

LMRA. The district court granted the motion and dismissed Rael’s complaint. 

II. Legal Background 

A. Rael’s State Law Claims

Rael alleged two tort claims under New Mexico law. To prevail on his IIED 

claim, he was required to show that he suffered severe emotional distress caused by 

defendants’ intentional or reckless conduct that was extreme and outrageous under 

the circumstances. See Coates v. Wal-Mart Stores, Inc., 976 P.2d 999, 1009 

(N.M. 1999). The elements of a prima facie tort claim are: “(1) an intentional and 

lawful act; (2) an intent to injure the plaintiff; (3) injury to the plaintiff as a result of 

the intentional act; (4) and the absence of sufficient justification for the injurious 

act.” Lexington Ins. Co. v. Rummel, 945 P.2d 992, 995 (N.M. 1997). Rael argues 

that neither of his state law tort claims is preempted by § 301. 

B. Section 301 Preemption 

 Section 301 of the LMRA provides: “Suits for violation of contracts between 

an employer and a labor organization representing employees in an industry affecting 

commerce as defined in this chapter . . . may be brought in any district court of the 

United States having jurisdiction of the parties . . . .” 29 U.S.C. § 185(a). This 

provision has been construed “as a congressional mandate to the federal courts to 

fashion a body of federal common law to be used to address disputes arising out of 
4 

labor contracts.” Allis-Chalmers Corp. v. Lueck, 471 U.S. 202, 209 (1985). Section 

301 is also deemed to have a preemptive effect, such that “[a] state rule that purports 

to define the meaning or scope of a term in a contract suit . . . is pre-empted by 

federal labor law.” Id. at 210. In Allis-Chalmers, the Supreme Court extended this 

rule beyond breach of contract claims, stating that “questions relating to what the 

parties to a labor agreement agreed, and what legal consequences were intended to 

flow from breaches of that agreement, must be resolved by reference to uniform 

federal law, whether such questions arise in the context of a suit for breach of 

contract or in a suit alleging liability in tort.” Id. at 211. Ultimately, the Court held 

that preemption depends on “whether evaluation of the tort claim is inextricably 

intertwined with consideration of the terms of the labor contract.” Id. at 213. 

Applying this test, the Supreme Court held in Lingle v. Norge Division of 

Magic Chef, Inc., 486 U.S. 399, 401 (1988), that a state law claim alleging a 

retaliatory discharge for filing a workers’ compensation claim was not preempted by 

§ 301. The Court reasoned that the “purely factual questions” necessary to prove the 

elements of this claim could be determined without interpreting any term of a CBA. 

Id. at 407 (noting the factual issues were whether an employee was discharged or 

threatened with discharge and whether the employer’s motivation was to deter the 

employee from exercising his workers’ compensation rights). Thus, under Lingle, 

“an application of state law is preempted by § 301 . . . only if such application 

requires the interpretation of a collective-bargaining agreement.” Id. at 413. 
5 

C. Tenth Circuit Cases Holding IIED Claims Preempted by § 301 

After Lingle, we have regularly held that IIED claims are preempted by § 301. 

In Johnson v. Beatrice Foods Co., 921 F.2d 1015, 1016 (10th Cir. 1990), the plaintiff 

alleged that he left his job as a delivery driver due to harassment by his supervisor. 

We held that his IIED claim was preempted because “[e]ach of [his] allegations 

directly relates to either explicit or implied rights derived from the CBA, just as the 

bad faith tort claim in Allis-Chalmers did.” Id. at 1020. Further, because an IIED 

claim under Oklahoma law “should not be considered in a sterile setting, detached 

from the milieu in which it took place,”1

 we held that “all aspects of [the plaintiff’s] 

employment, including the terms of the CBA, must be considered when evaluating 

whether [his employer’s] conduct was outrageous.” Id. (internal quotation marks 

omitted). More specifically, we concluded that “it cannot be determined whether [the 

employer’s] conduct was outrageous without determining whether the conduct was 

allowed under the CBA. Indeed, actions that the CBA permits might be deemed 

reasonable in virtue of the fact that the CBA permits them.” Id. (brackets and 

internal quotation marks omitted). Finally, we determined that Lingle was inapposite 

because, unlike a state statute that specifically prohibits firing an employee for 

exercising rights under a workers’ compensation act, the state law IIED claim in 

Johnson did not “create an independent method of measuring when an employer’s 

work-related conduct is outrageous.” Id. at 1021. 

 1

 Rael does not argue that an IIED claim under New Mexico law requires a 

different analysis. 
6 

Our subsequent decisions have largely followed Johnson in holding that IIED 

claims are preempted by § 301. See Mowry v. United Parcel Serv., 415 F.3d 1149, 

1158 (10th Cir. 2005) (determination whether alleged conduct was outrageous 

required construction of employer’s rights and obligations under the CBA); Steinbach 

v. Dillon Cos., 253 F.3d 538, 542 (10th Cir. 2001) (same); Garley v. Sandia Corp., 

236 F.3d 1200, 1214 (10th Cir. 2001) (same, as to part of IIED claim); Mock v. T.G. 

& Y. Stores Co., 971 F.2d 522, 530 (10th Cir. 1992) (same). 

D. Tenth Circuit Cases Holding IIED Claims Not Preempted by § 301 

We have also held that some IIED claims were not preempted by § 301. 

Although we held that part of the plaintiff’s IIED claim was preempted in Garley, we 

concluded that it was not preempted to the extent that the claim was based on the 

employer’s conduct after an arbitrator ordered the plaintiff’s reinstatement. 236 F.3d 

at 1214. We emphasized this portion of the IIED claim was not preempted by § 301 

because it was based on allegations regarding the employer’s “retaliatory acts”; thus, 

as with the plaintiff’s “independent cause of action for retaliation, determining 

whether [the employer’s] acts are ‘outrageous’ would not require resort to the CBA.” 

Id.

In two more cases, we held that IIED claims were not preempted based on the 

nature of the alleged conduct. In Albertson’s, Inc. v. Carrigan, 982 F.2d 1478, 1479 

(10th Cir. 1993), the plaintiff brought a state law claim for extreme and outrageous 

conduct, alleging that she was suspended after the defendants conspired to falsely 

accuse her of shoplifting. Relying on Lingle, we held that the plaintiff’s state law 
7 

claim was not preempted by § 301 because “if [she] can show defendants conspired 

to have [her] arrested by fabricating her theft of groceries from her employer, proving 

their outrageous conduct need not require interpretation of or reference to the CBA.” 

Id. at 1482; see also id. at 1483 (citing earlier Supreme Court decision holding that 

IIED claims were not preempted by another provision of the LMRA where the 

alleged conduct was “particularly abusive”). 

We also held that IIED claims were not preempted in Fry v. Airline Pilots 

Ass’n, International, 88 F.3d 831, 841 (10th Cir. 1996).2

 The plaintiffs were airline 

pilots who continued working when their union went on strike. In support of their 

IIED claims against the union, the pilots presented evidence that they and their 

families were targeted with “massive abuse” intended to punish them, drive them 

from their jobs, and deter other union members from crossing future picket lines. Id.

at 840. The harassment campaign included “food and drink contamination, property 

loss and property damage, death threats and threats of physical harm, threats of 

sexual assault of spouses and family members, and harassing phone calls and knocks 

on the door during the night on flight layovers, among other acts of harassment and 

intimidation.” Id. (internal quotation marks omitted). We held that the pilots’ IIED 

claims were not preempted because it was unnecessary to interpret the CBA to find 

liability for outrageous conduct on these facts. Id. at 841. In reaching this 

 2

 In Fry, we considered preemption under the Railway Labor Act rather than 

§ 301 of the LMRA. But this court applies the Lingle preemption standard under 

both statutes. 88 F.3d at 835-36. 
8 

conclusion, we cited a Seventh Circuit case holding that an IIED claim was not 

preempted by § 301 where the conduct alleged was “‘not even arguably sanctioned 

by the labor contract.’” Id. (quoting Keehr v. Consol. Freightways of Del., Inc., 

825 F.2d 133, 138 n.6 (7th Cir. 1987)). 

III. Analysis 

We review de novo the district court’s dismissal of Rael’s complaint for 

failure to state a claim on which relief can be granted. See Garley, 236 F.3d at 1206; 

see also id. at 1203 (reviewing district court’s grant of motion to dismiss for failure 

to state a claim based on § 301 preemption). “Whether state law is preempted by 

federal law is a conclusion of law which we also review de novo.” Id.

A. Under the Reasoning in Johnson, Rael’s State Law Tort Claims are 

Preempted by § 301 

 Applying Johnson and its progeny, the district court held that Rael’s IIED 

claim is preempted by § 301. It reasoned that, as in Johnson, Rael’s allegations 

directly relate to explicit and implied rights derived from the CBA. The court 

pointed to CBA provisions granting Smith’s the sole right and function “to maintain 

the discipline and efficiency of the employees,” Aplt. App. at 47 (CBA § 6.1), and 

prohibiting “the use of profanity, raised voices and harassment” in the workplace, id.

at 78 (CBA § 26). The court concluded that “[w]hether Suazo’s comments 

constituted harassment as opposed to an appropriate evaluation of a subordinate’s 

efficiency requires an interpretation of the CBA.” Id. at 128. It further held that “the 

allegations in the present case do not rise to the level of the clearly outrageous 
9 

conduct in Albertson’s . . . and do not lend themselves to such a clear cut 

determination.” Id. at 130. 

The district court held that Rael’s prima facie tort claim is also preempted by 

§ 301 because “[a]s is the case with determining the ‘outrageousness’ of conduct in 

the [IIED] context, determining whether the conduct was ‘justified’ cannot be 

evaluated without resort to the [CBA].” Id. at 132. The court reasoned that his prima 

facie tort claim “lacks an independent method of measuring whether the employer’s 

alleged conduct was justified.” Id. Rael does not separately challenge the district 

court’s reasoning in dismissing his prima facie tort claim.3

Rael argues that Suazo’s conduct could not arguably be sanctioned by the 

CBA. See Aplt. Opening Br. at 14 (citing Keehr, 825 F.2d at 138 n.6). But we agree 

with the district court that the facts underlying Rael’s state law claims are more akin 

to the allegations in Johnson than in Albertson’s. Like Rael, the plaintiff in Johnson

alleged that his supervisor yelled at him, verbally abused him, and frequently called 

him names in the presence of co-workers. 921 F.2d at 1017. Moreover, Johnson also 

involved other conduct that is more egregious than any of the treatment alleged by 

 3

 The district court dismissed both of Rael’s preempted claims rather than 

treating them as arising under § 301 because Rael did not demonstrate that he had 

exhausted his available remedies under the CBA. Rael does not challenge this aspect 

of the district court’s decision. 
10 

Rael.4

 Yet we held that it was necessary to construe the applicable CBA to determine 

whether the supervisor’s alleged conduct was outrageous. Id. at 1020. 

In reaching our holding in Johnson, we acknowledged our sister circuits’ 

varying decisions applying § 301 preemption to IIED claims. Id. at 1021. But we 

nonetheless held that Allis-Chalmers and Lingle necessitated our preemption 

conclusion. Id. at 1021-22. Johnson is binding precedent in this circuit; if not 

distinguishable, it controls our result in this case, see United States v. Edward, 

224 F.3d 1216, 1220 (10th Cir. 2000) (“Under the doctrine of stare decisis, this panel 

cannot overturn the decision of another panel of this court barring en banc 

reconsideration, a superseding contrary Supreme Court decision, or authorization of 

all currently active judges on the court.” (internal quotation marks omitted)). 

 B. Rael’s Arguments why Johnson is distinguishable 

 Rael advances two arguments why his case is distinguishable from Johnson. 

He first contends that the determining factor for § 301 preemption is whether the 

employee “suffered emotional distress caused by [his] employer in a matter involving 

employee discipline, or in a matter involving the disciplinary process.” Aplt. 

Opening Br. at 6. If it did, Rael argues that the tort claim is preempted; but if the 

 4

 The delivery-driver plaintiff in Johnson alleged that his supervisor, among 

other things, encouraged one co-worker to shun him and others to follow him around; 

told a co-worker to ignore theft by other drivers and instead devote his time to getting 

rid of the plaintiff; publicly ridiculed the plaintiff, falsely claiming he had the most 

“bad product” on his route; rearranged the plaintiff’s route, making it more difficult 

to run; made it impossible to properly service a particular customer; planted bad 

product on the plaintiff’s route, then disciplined the plaintiff for it; and suspended the 

plaintiff for leaving bad product with a customer, knowing it was left by a different 

driver. 921 F.2d at 1017-18. 
11 

claim arose “outside of the disciplinary context,” id. at 7, Rael contends that 

preemption is not generally applied. He argues that his tort claims are not preempted 

by § 301 because, unlike the IIED allegations in Johnson, Rael’s claims are based on 

conduct by Suazo outside of a disciplinary context. Rael also contends that Johnson

is distinguishable because, unlike the CBA in Johnson, the Smith’s CBA lacks a 

clearly applicable grievance procedure. Neither contention has merit. 

1. Rael Fails to Show that § 301 Preemption Applies Only to 

IIED Claims Involving Conduct Related to a Disciplinary 

Process 

 Rael maintains that there is a line of cases demonstrating his proposition that 

§ 301 preempts only tort claims based on conduct that occurred within a disciplinary 

process. But he points to no case expressly holding that preemption turns on this 

factor. Nor do all of his cases align with his proposition. 

Johnson, itself, does not support it. Although the conduct alleged in Johnson

involved workplace harassment both in and outside of a disciplinary context,5

 we 

held that § 301 preempted all of the plaintiff’s IIED allegations, 921 F.2d at 1020. 

Moreover, we specifically disagreed with the district court to the extent it limited its 

preemption holding to the plaintiff’s allegations related to suspensions or disciplinary 

 5

 The allegedly outrageous conduct in Johnson included written warnings, 

suspensions, and terminations, as well as other actions not allegedly related to any 

disciplinary action or process. See 921 F.2d at 1017-18. 
12 

actions, stating that “since the CBA also allows ‘disputes’ to be grieved, we would 

hold that all of [his] allegations are pre-empted.” Id. at 1020.6

Rael’s response is that Johnson is an “outlier” case, Aplt. Opening Br. at 10, 

and he attempts, without success, to assemble a line of other cases clearly supporting 

his proposition. Rael is correct that, when we have followed Johnson in finding IIED 

claims were preempted by § 301, the cases involved conduct that occurred within a 

disciplinary context. See Mowry, 415 F.3d at 1158 (termination); Steinbach, 

253 F.3d at 539 (cancellation of employee’s vacation on threat of termination and 

initiation of disciplinary proceedings); Garley, 236 F.3d at 1214 (investigation of 

employee and termination); Mock, 971 F.2d at 530 (investigation of employees and 

termination). But our non-preemption holdings in Albertson’s and Garley do not 

clearly support Rael’s proposition. 

In Albertson’s, the plaintiff alleged that she was suspended from employment 

based on a false accusation of shoplifting. 982 F.2d at 1479. In holding that her 

“single state law claim” of extreme and outrageous conduct7

 was not preempted by 

 6

 Contrary to Rael’s assertion, see Aplt. Opening Br. at 12, we did not dismiss 

the plaintiff’s non-disciplinary allegations in Johnson because they were insufficient 

to sustain an IIED claim. We did hold that the supervisor’s alleged statements and 

actions related to the plaintiff’s divorce were arguably not “work-related,” and we 

held that those allegations were insufficient, on their own, to support an IIED claim. 

921 F.2d at 1020 n.3 (emphasis added). But we held that the plaintiff’s remaining 

allegations—involving conduct both within and outside of a disciplinary context—

were preempted by § 301. Id. at 1020. 

7

 The district court had construed the plaintiff’s complaint as bringing two 

claims: one based on her suspension and one based on the conspiracy to charge her 

with shoplifting. 982 F.2d at 1479. 
13 

§ 301, we distinguished Johnson and other previous decisions in which the 

outrageousness of the alleged conduct could not be determined without interpreting 

the CBAs. Id. at 1481-82. Thus, we did not hold that the claim avoided § 301 

preemption because the allegedly outrageous conduct occurred outside of a 

disciplinary context. Rather, we acknowledged that her outrageous conduct claim 

would require a determination of the same factual issues and disputes as her separate 

challenge to her suspension, which she was pursuing through arbitration under the 

CBA. Id. at 1482.

In Garley, we held that part of the plaintiff’s IIED claim was not preempted 

because it was based on the employer’s “retaliatory acts,” not because the conduct 

occurred outside of a disciplinary process. 236 F.3d at 1214 (citing the court’s prior 

analysis regarding the employee’s retaliation claim). Moreover, the allegations 

underlying the non-preempted IIED claim in Garley arguably involved conduct 

related to a disciplinary process. The employee claimed that his employer retaliated 

by refusing to provide the relief he was entitled to under an arbitrator’s reinstatement 

ruling that followed his termination. See 236 F.3d at 1205, 1214. Two other cases 

Rael cites similarly found that retaliation-based IIED claims were not preempted by 

§ 301. See Meyer v. Schnucks Mkts., Inc., 163 F.3d 1048, 1049, 1051-52 (8th Cir. 

1998) (holding IIED claim based on harassment in retaliation for employee’s 

complaints about sanitation and selling outdated meat was not preempted by § 301); 

Krashna v. Oliver Realty, Inc., 895 F.2d 111, 115 (3d Cir. 1990) (holding IIED claim 
14 

based on harassment and termination after filing workers’ compensation claim was 

not preempted by § 301).8

Finally, Rael mischaracterizes another case. He contends that Douglas v. 

American Information Technologies Corp., 877 F.2d 565 (7th Cir. 1989), involved 

only “discipline,” Aplt. Opening Br. at 7. The plaintiff did allege “an unjustified 

final warning” and a threat of termination, but she also alleged forced participation in 

stressful work, unwarranted scrutiny of her work, and constant harassment. 877 F.2d 

at 567-68. Yet the court held that her IIED claim was preempted by § 301 because 

its resolution would require interpretation of the CBA. Id. at 572-73. 

Rael fails to show there is a line of cases in which § 301-preemption rulings 

have turned on whether the state law claim arose from conduct within a disciplinary 

process. Nor has he distinguished Johnson as an “outlier” as to any such line of 

cases. Moreover, it is unsurprising that many of the cases applying § 301 preemption 

to IIED claims have involved allegations of outrageous conduct that occurred within 

a disciplinary process, as that subject is often addressed by the terms of a CBA. See, 

e.g., Mock, 971 F.2d at 530 (IIED claim related to manner of employee investigation 

and termination required interpretation CBA provision permitting termination for 

“just cause.”). But § 301 preemption extends to any state law claim that requires 

 8

 Rael acknowledges that Krashna involved allegations of harassment not 

related to discipline (e.g., increasing the amount of the employee’s workload, 

impugning him orally, and taking other acts “to harass and annoy” him), as well as 

termination of the employee. 895 F.2d at 115 & n.5. But despite the 

disciplinary-related allegation, the court held that the plaintiff’s IIED claim was not 

preempted by § 301. Id. at 115. 
15 

interpretation of any CBA term. What “matters for § 301 pre-emption purposes [is 

whether] resolution of the state-law claim does not require construing the 

collective-bargaining agreement.” Lingle, 486 U.S. at 407. 

2. Rael Also Fails to Show that the Smith’s CBA Lacks a 

Grievance Procedure Applicable to His Claims 

Rael also attempts to distinguish Johnson on the basis that the Smith’s CBA 

“does not provide a[] clear and express procedure for [him] to grieve his harassment 

and bullying.” Aplt. Opening Br. at 18.9

 We noted in Johnson that the plaintiff 

“could have used the CBA grievance procedure for any of the allegations in his 

complaint since all the allegations involved either a suspension, discharge, or 

work-related dispute.” 921 F.2d at 1020. Therefore, because “disputes” were 

grievable under the CBA, we did not limit our § 301-preemption ruling to the 

plaintiff’s IIED claims related to suspensions and disciplinary actions. Id. 

Rael argues that, unlike in Johnson, he could not redress his claims under the 

grievance provisions in the Smith’s CBA. He contends that Suazo’s harassment was 

 9

 Although Rael does not explain why grievability of his claim is relevant, the 

Supreme Court has said that § 301 preemption “preserves the central role of 

arbitration” in labor disputes. Allis-Chalmers, 471 U.S. at 219; see also Lingle, 

486 U.S. at 411 n.11 (noting arbitration is called for in most CBAs). Thus, a 

preemption rule 

that permitted an individual to sidestep available grievance procedures 

would cause arbitration to lose most of its effectiveness, as well as 

eviscerate a central tenet of federal labor contract law under § 301 that it is 

the arbitrator, not the court, who has the responsibility to interpret the labor 

contract in the first instance. 

Allis-Chalmers, 471 U.S. at 220 (citation omitted). 
16 

not grievable because the anti-harassment provision in the CBA is merely 

aspirational and unenforceable and the grievance provision is ambiguous. Rael bases 

these contentions entirely on the absence of an express statement in the CBA that a 

violation of the anti-harassment provision is grievable. 

But Smith’s argues that Rael’s allegations are grievable under the CBA. 

Smith’s points to the broad language of the grievance provision itself: 

The Union or any employee in the Bargaining Unit who has any 

dispute or disagreement of any kind or character arising out of or in any 

way involving the interpretation or application of this Agreement, shall 

submit such dispute or disagreement for resolution under the procedures 

and in the manner set forth in this Section. 

Aplt. App. at 66 (CBA § 15.1). Rael does not explain why he could not grieve 

Suazo’s alleged harassment under this expansive grievance language (as 

supplemented by implied contractual rights and “the common law of the shop,” 

Johnson, 921 F.2d at 1020). He also notes that “harassment” is not defined in the 

CBA. But the final step in the CBA’s grievance process is arbitration. Aplt. App. at 

67 (CBA § 15.2(c)). And under § 301, it is the arbitrator who must interpret the 

CBA’s anti-harassment provision in the first instance. Allis-Chalmers, 471 U.S. at 

220. Rael again fails to show that his case is distinguishable from Johnson. 

C. Rael Also Fails to Establish that his Individual Claims against 

Suazo are not Preempted by § 301 

In his final contention, Rael argues the district court erred in holding that his 

individual claims against Suazo are preempted. The court based its ruling on 

Steinbach, which affirmed the dismissal of an IIED claim brought against both the 
17 

plaintiff’s former employer and her supervisor because the claim was preempted by 

§ 301. 253 F.3d at 539. Rael asserts that Steinbach has not been cited for this 

proposition, but he fails to point to any decision holding that claims against a 

supervisor are not preempted. Nor did he provide any support for this contention in 

the district court. See Aplt. App. at 132 (district court’s dismissal order noting that 

“Plaintiff cites no authority for this proposition”). We decline to address an 

argument for which Rael provides no legal authority. See United States v. Banks, 

451 F.3d 721, 728 (10th Cir. 2006).
