Appeal from the United States District Court
for the Eastern District of Washington
Stanley A. Bastian, Chief District Judge, Presiding
Argued and Submitted December 8, 2023
Seattle, Washington
Before: McKEOWN, N.R. SMITH, and SANCHEZ, Circuit Judges.
Plaintiffs-Appellants Dru Choker and Matthew DeMarco (“Plaintiffs”) are
licensed veterinarians who are former employees and shareholders of Defendant-
Appellee Pet Emergency Clinic, P.S. (“PEC”). They allege that PEC and
Defendant-Appellee National Veterinary Associates, Inc. (“NVA”) tried to “create
a closed network” for emergency veterinary services in the Spokane area by
merging and imposing non-solicitation, mandatory referral, and non-competition
2
agreements on PEC employees and shareholders. Plaintiffs sued PEC and NVA
and brought claims under Section 1 and Section 2 of the Sherman Act (15 U.S.C.
§1 and §2) and their Washington state analogues (RCW 19.86.030 and RCW
19.86.040).
Plaintiffs appeal the district court’s grant of summary judgment over their
federal claims. PEC and NVA cross-appeal the district court’s refusal to exercise
supplemental jurisdiction over Plaintiffs’ state antitrust claims. PEC and NVA
also conditionally cross-appeal a separate order denying their motions to exclude
testimony from Plaintiffs’ antitrust expert. We have jurisdiction under 28 U.S.C. §
1291. We review de novo the district court’s grant of summary judgment and
whether a plaintiff has antitrust standing. See Am. Ad Mgmt., Inc. v. Gen. Tel. Co.
of California, 190 F.3d 1051, 1054 (9th Cir. 1999). We affirm.
1. Plaintiffs contend they suffered antitrust injury when their
employment was terminated after they refused to sign PEC’s allegedly anti-
competitive employment agreements. We have held, however, that “[t]he loss of a
job is not the type of injury that the antitrust laws were designed to prevent”
because “[a] plaintiff who is neither a competitor nor a consumer in the relevant
market does not suffer antitrust injury.” Vinci v. Waste Mgmt., Inc., 80 F.3d 1372,
3
1376 (9th Cir. 1996) (internal citations and quotation marks omitted).1
2. Plaintiffs also argue that they suffered an antitrust injury when they
were excluded from the Spokane market and compelled to open their emergency
veterinarian clinic in Coeur d’Alene, Idaho. Plaintiffs’ allegations are too
speculative to confer antitrust standing. An antitrust injury must be the “direct
result” of the defendant’s conduct. City of Oakland v. Oakland Raiders, 20 F.4th
441, 458 (9th Cir. 2021) (citation omitted). Antitrust injury “may not be derivative
and indirect” or “secondary, consequential, or remote.” Id. (quotation marks and
citation omitted). Plaintiffs’ market exclusion theory does not meet this standard.
It is undisputed that Plaintiffs were never subject to any of the agreements
they contend would have excluded them from the Spokane market. Plaintiffs never
signed and were never subject to PEC’s proposed employment agreement, and
NVA’s and PEC’s proposed shareholder restrictions never took effect because
NVA never merged with PEC. Indeed, as Plaintiffs acknowledge in their opening
brief, after their termination of employment “Drs. DeMarco and Choker were now
1
In its amicus brief, the United States takes no position on the merits of Plaintiffs’
claims but notes that Ostrofe v. H.S. Crocker Co., 740 F.2d 739 (9th Cir. 1984),
allows for the recognition of antitrust standing for dismissed employees under
certain circumstances. Plaintiffs now seek to rely on Ostrofe to establish antitrust
injury. But Plaintiffs did not cite Ostrofe either below or in their opening brief
before this Court and cannot “raise new issues on appeal to secure a reversal of the
lower court’s summary judgment determination.” BankAmerica Pension Plan v.
McMath, 206 F.3d 821, 825 (9th Cir. 2000).
4
fully able to directly compete in the Spokane market.” Plaintiffs’ assertion of
market exclusion damages—“debt, start-up costs, substantial time recreating an
emergency hospital, and loss of ongoing income, stress, and hardship”—thus stems
from Plaintiffs’ fear that PEC and NVA would eventually merge and impose
competitive restrictions.
However, Plaintiffs “cannot manufacture standing merely by inflicting harm
on themselves based on their fears of hypothetical future harm that is not certainly
impending.” Clapper v. Amnesty Int'l USA, 568 U.S. 398, 416 (2013).2 Plaintiffs
failed to show that at the time they incurred market exclusion damages, the alleged
anti-competitive restrictions from an NVA/PEC merger were certainly impending.
Plaintiffs put a down payment on their veterinary clinic in Coeur d’Alene months
before a non-binding Letter of Intent between PEC and NVA was signed.
Moreover, PEC and NVA could not have forced Plaintiffs (or any unwilling
shareholder) to accept restrictions associated with any merger in light of statutory
dissenters’ rights available under Washington law. See RCW 23B.13.020(1)(a).
Plaintiffs’ market exclusion theory based on the possibility of a merger is simply
2
While Clapper analyzed injury in the context of Article III standing, similar
principles apply to antitrust standing, which also assesses the directness of the
alleged injury. See Oakland Raiders, 20 F.4th at 458 (explaining that the second
factor in the antitrust standing inquiry “focuses on the chain of causation between
the plaintiff’s injury and the alleged restraint of trade”) (cleaned up).
5
too attenuated to confer antitrust standing.3
3. The district court did not abuse its discretion in declining to exercise
supplemental jurisdiction over Plaintiffs’ state law antitrust claims. The court was
not required to provide an explanation for declining to exercise supplemental
jurisdiction when, as here, it cited 28 U.S.C. § 1367(c)(3). See San Pedro Hotel
Co., Inc. v. City of Los Angeles, 159 F.3d 470, 478 (9th Cir. 1998); Ove v. Gwinn,
264 F.3d 817, 826 (9th Cir. 2001).
4. Having affirmed the district court’s dismissal of Plaintiffs’ claims, we
do not reach NVA’s and PEC’s conditional cross-appeals challenging the district
court’s orders denying their motions to exclude testimony from Plaintiffs’ antitrust
expert.
AFFIRMED.
3
The Government’s amicus brief also discusses Plaintiffs’ potential status as
“nascent” competitors. But as the Government’s counsel acknowledged at
argument, whether a plaintiff is a nascent competitor does not obviate the separate
inquiry whether a plaintiff has suffered antitrust injury sufficient to confer antitrust
standing. Because Plaintiffs did not raise any nascent competitor theory before the
District Court, we deem the issue waived. See BankAmerica, 206 F.3d at 825.
