I. INTRODUCTION
Plaintiff Terrence M. Wyles appeals the district court’s grant of summary
judgment in favor of Defendants Allen Zachary Sussman and Loeb & Loeb, LLP on
his claim of malicious prosecution. Exercising jurisdiction under 28 U.S.C. § 1291,
we affirm.
II. BACKGROUND
Wyles is a Colorado attorney who briefly worked as in-house counsel for
Aluminaid, Inc., which terminated him in April 2013. In July 2013 the company,
under the new name of West Hills Research and Development, Inc., sued Wyles in
California state court. The complaint asserted 12 causes of action, including claims
for breach of fiduciary duty, misappropriation of trade secrets, and intentional and
negligent interference with economic advantage. Loeb & Loeb represented West
Hills in the lawsuit, and Sussman was a partner at the firm.
In September 2016 the California court learned that West Hills’ corporate
status had been suspended. It issued an order to show cause why the case should not
be dismissed “if the status issue is not taken care of.” Aplt. App., Vol. I at 145. Then,
“[b]ased on the representation of counsel that [West Hills’ corporate status] is still
suspended,” the court in October dismissed the case without prejudice “for [West
Hills’] failure to be able to proceed as a corporate entity.” Id. at 150.
In August 2017 Wyles filed the present action in the United States District
Court for the District of Colorado, raising multiple claims against multiple
2 Appellate Case: 24-1226 Document: 46-1 Date Filed: 06/23/2025 Page: 3
defendants. Among the claims was a claim against Defendants for malicious
prosecution arising out of their involvement in the California lawsuit. Defendants
successfully moved for summary judgment on that claim. The court ruled that Wyles
could not establish one of the elements of malicious prosecution—that the California
lawsuit “was terminated in [his] favor.” Id., Vol. IV at 485. Judgment has been
entered on all claims against all defendants.
This appeal concerns only the court’s summary judgment on the malicious-
prosecution claim.
III. DISCUSSION
A. Standard of Review
“We review the district court’s grant of summary judgment de novo, applying
the same legal standard that the district court is to apply.” N.H. Ins. Co. v. TSG Ski &
Golf, LLC, 128 F.4th 1337, 1344 (10th Cir. 2025). Summary judgment is appropriate
if “there is no genuine dispute as to any material fact and the movant is entitled to
judgment as a matter of law.” Fed. R. Civ. P. 56(a).
When, as in this case, a federal court is exercising diversity jurisdiction, it
must apply “state law to the substantive issues of the appeal[] and determine which
state’s law applies by using the forum state’s choice-of-law rule.” Gorsuch, Ltd. v.
Wells Fargo Nat. Bank Ass’n, 771 F.3d 1230, 1236 n.7 (10th Cir. 2014). The parties
disagree over whether Colorado or California law applies to this action. But because
the parties agree that there is no outcome-determinative conflict between Colorado
3 Appellate Case: 24-1226 Document: 46-1 Date Filed: 06/23/2025 Page: 4
and California law as to the malicious-prosecution claim, we need not resolve the
choice-of-law issue. See Dummar v. Lummis, 543 F.3d 614, 619 (10th Cir. 2008).
B. Malicious Prosecution
The parties do not dispute that in both Colorado and California, a claim for
malicious prosecution requires the plaintiff to establish that the previous action,
which was allegedly prosecuted maliciously (here the suit against Wyles by West
Hills), ended in his favor. See Hewitt v. Rice, 154 P.3d 408, 411 (Colo. 2007)
(“Generally, to prevail on a claim for malicious prosecution, the following elements
must be satisfied: (1) the defendant contributed to bringing a prior action against the
plaintiff; (2) the prior action ended in favor of the plaintiff; (3) no probable cause; (4)
malice; and (5) damages.” (emphasis added)); Parrish v. Latham & Watkins, 400
P.3d 1, 7 (Cal. 2017) (“The common law tort of malicious prosecution . . . consists of
three elements. The underlying action must have been: (i) initiated or maintained by,
or at the direction of, the defendant, and pursued to a legal termination in favor of
the malicious prosecution plaintiff; (ii) initiated or maintained without probable
cause; and (iii) initiated or maintained with malice.” (emphasis added and citations
and internal quotation marks omitted)). In particular, the termination must be based
on the merits of the previous action in a manner indicating the nonliability of the
malicious-prosecution plaintiff. See Hewitt, 154 P.3d at 410 (“Favorable termination
is a question of law requiring an action to be resolved on the merits in favor of the
party claiming malicious prosecution.” (emphasis added)); Hewitt, 119 P.3d 541, 544
(Colo. App. 2004), aff’d, 154 P.3d. 408 (“To show a termination in one’s favor, a
4 Appellate Case: 24-1226 Document: 46-1 Date Filed: 06/23/2025 Page: 5
plaintiff must prove that the court passed on the merits of the charge or claim against
him in such circumstances as to show one’s innocence or non-liability, or show that

4 Appellate Case: 24-1226 Document: 46-1 Date Filed: 06/23/2025 Page: 5
plaintiff must prove that the court passed on the merits of the charge or claim against
him in such circumstances as to show one’s innocence or non-liability, or show that
the proceedings were terminated or abandoned at the instance of the defendant in
circumstances that fairly imply the plaintiff’s innocence.” (internal quotation marks
omitted)); Siebel v. Mittlesteadt, 161 P.3d 527, 531 (Cal. 2007) (to establish
favorable termination “the termination must reflect the merits of the action and
plaintiff’s innocence of the misconduct alleged in the lawsuit” (emphasis added and
internal quotation marks omitted)).
Wyles argues that the district court erred in determining that he could not
satisfy the favorable-termination element of malicious prosecution. He contends that
“there is no question” that the California lawsuit was terminated in his favor, “as he
was no longer subject to the liability which Defendants sought to impose on him.”
Aplt. Br. at 8. We disagree. That is not the standard for favorable termination.
Here, the California court dismissed West Hills’ action against Wyles without
prejudice because the company’s corporate status was suspended, and it therefore
lacked the legal capacity to sue. See Casiopea Bovet, LLC v. Chiang, 12 Cal. App.
5th 656, 662 (Cal. Ct. App. 2017) (“A corporation that has had its powers suspended
lacks the legal capacity to prosecute or defend a civil action during its suspension.”
(internal quotation marks omitted)). The court’s order stated: “Based on the
representation of counsel that [West Hills] is still suspended, this case is
DISMISSED for [West Hills’] failure to be able to proceed as a corporate entity.”
Aplt. App., Vol. I at 150. The notice of ruling stated that “[t]he court dismissed the
5 Appellate Case: 24-1226 Document: 46-1 Date Filed: 06/23/2025 Page: 6
entire action without prejudice.” Id. at 152. In no way did this ruling reflect on the
merits of West Hills’ legal claims against Wyles. Indeed, the suit could be revived if
West Hills regained corporate status.
Although Wyles maintains that Colorado law applies, he argues in the
alternative that “[i]n some circumstances, if there is a termination other than on the
merits, California creates a jury issue as to whether the termination was favorable.”
Aplt. Br. at 8. For support, he cites Fuentes v. Berry, 38 Cal. App. 4th 1800, 1808
(Cal. Ct. App. 1995). But that case stands only for the proposition that if there is a
conflict “as to the circumstances explaining a failure to prosecute an action further,
the determination of the reasons underlying the dismissal is a question of fact.” Id. at
1808. Here, however, there is no question about the circumstances or reasons
underlying the termination of the California lawsuit. The court unequivocally
dismissed the action because West Hills’ corporate status was suspended, not because
the company’s claims against Wyles were without merit.
We agree with the district court’s ruling that Wyles cannot establish a
necessary element of malicious prosecution.
IV. CONCLUSION
We AFFIRM the judgment below.
