MOLLY C. DWYER, CLERK
U.S. COURT OF APPEALS
FOR THE NINTH CIRCUIT
JOSE NAVARRO, No. 23-3274
D.C. No.
Plaintiff - Appellant, 2:17-cv-02477-DSF-SK
v. MEMORANDUM*
EXXON MOBIL CORPORATION, a New
Jersey corporation, et al.,
Defendants - Appellees.
Appeal from the United States District Court
for the Central District of California
Dale S. Fischer, District Judge, Presiding
Argued and Submitted March 24, 2025
Pasadena, California
Before: BOGGS**, FRIEDLAND, and BRESS, Circuit Judges.
Plaintiff Jose Navarro appeals the district court’s dismissal on the pleadings
of his trespass claim, grant of summary judgment to Defendants on his nuisance
claims, and decertification of the Ground and Air Subclasses. We have jurisdiction
*
This disposition is not appropriate for publication and is not precedent
except as provided by Ninth Circuit Rule 36-3.

The Honorable Danny J. Boggs, United States Circuit Judge for the
U.S. Court of Appeals for the Sixth Circuit, sitting by designation.
under 28 U.S.C. § 1291. We reverse the district court’s dismissal on the pleadings
of Navarro’s individual trespass claim and vacate its decertification of the Ground
Subclass, and we remand for further proceedings consistent with this decision. We
affirm the district court’s grant of summary judgment as to Navarro’s individual
nuisance claims and do not reach Navarro’s appeal of the decertification of the Air
Subclass.
1. “We review de novo the district court’s dismissal of plaintiff’s complaint
for failure to state a claim under [Federal Rule of Civil Procedure] 12(b)(6).”
Prodanova v. H.C. Wainwright & Co., LLC, 993 F.3d 1097, 1105 (9th Cir. 2021)
(quoting Lipton v. Pathogenesis Corp., 284 F.3d 1027, 1035 (9th Cir. 2002)).
Navarro’s trespass claim, as alleged in the operative Corrected Third Amended
Complaint, Dist. Ct. Dkt. 260, was based on groundwater and soil contamination as
well as resulting soil vapor, and Navarro did not narrow the claim to be based
solely on soil vapor. The reply in support of the motion to appoint Navarro as
class representative, Dist. Ct. Dkt. 266, which stated that “[t]he trespass claim . . .
is premised on evidence that subsurface contamination from the Refinery poses a
vapor intrusion risk to the structures in the class area,” is consistent with the theory
advanced in the operative complaint that groundwater or soil contamination
constitutes a trespass and the soil vapors are part of the alleged harm resulting from
that trespass. That reply further stated that the trespass claim was “unchanged”
2 23-3274
from prior complaints, which had set forth a broader theory of trespass than just
soil-vapor intrusion. Similarly, although Navarro’s opposition to Defendants’
motion for judgment on the pleadings, Dist. Ct. Dkt. 297, argued that soil vapor
alone could support a trespass claim, it did not waive a trespass theory based also
on soil and groundwater contamination.
Under California law, soil and groundwater contamination such as Navarro
alleges here can support a claim for trespass. See, e.g., Newhall Land & Farming
Co. v. Super. Ct., 23 Cal. Rptr. 2d 377, 383-84 (Cal. Ct. App. 1993) (holding that
plaintiffs could state a trespass claim based on allegations of soil and groundwater
contamination from petroleum products); KFC W., Inc. v. Meghrig, 28 Cal. Rptr.
2d 676, 685-86 (Cal. Ct. App. 1994) (same). The district court’s dismissal on the
pleadings of Navarro’s individual trespass claim was based on an overly narrow
interpretation of Navarro’s trespass allegations and is therefore reversed.
Because the district court’s decertification of the Ground Subclass was
similarly predicated on its narrow construction of Navarro’s and other class
members’ trespass claims, the decertification of the Ground Subclass is vacated
and remanded for reconsideration under the broader trespass theory.
2. We review de novo the district court’s decision to grant summary
judgment. Desire, LLC v. Manna Textiles, Inc., 986 F.3d 1253, 1259 (9th Cir.
2021). We must determine, viewing the evidence in the light most favorable to the
3 23-3274
nonmoving party, “whether there are any genuine issues of material fact and
whether the district court correctly applied the relevant substantive law.” Soc.
Techs. LLC v. Apple Inc., 4 F.4th 811, 816 (9th Cir. 2021) (quoting KP Permanent
Make-Up, Inc. v. Lasting Impression I, Inc., 408 F.3d 596, 602 (9th Cir. 2005)).
Under California law, proving a nuisance claim requires showing, inter alia, that
“the invasion of the plaintiff’s interest in the use and enjoyment of the land [is]
substantial, i.e., that it cause[s] the plaintiff to suffer substantial actual damage.”
San Diego Gas & Elec. Co. v. Super. Ct., 13 Cal. 4th 893, 938 (1996) (internal
quotation marks omitted). Here, Navarro did not create a triable issue regarding
substantial harm because he did not explain why the evidence that he presented of
health risks from air pollution—which showed risk at levels that trigger public-
notice requirements but not mandatory regulatory action—constitutes substantial
harm. The potentially stronger arguments that Navarro now raises on appeal about
the risks from exposure to ground contamination were not adequately presented to
the district court and thus did not create a triable issue.
Because Navarro’s individual nuisance claims fail, he “cannot represent
others who may have” such claims, and his “bid to serve as a class representative
must fail.” Lierboe v. State Farm Mut. Auto. Ins. Co., 350 F.3d 1018, 1022
(9th Cir. 2003). That principle “is dispositive of the appeal of the class
certification,” so we have no need to consider Navarro’s appeal of the
4 23-3274
decertification of the Air Subclass. Id. at 1022-23.
AFFIRMED in part, REVERSED in part, VACATED in part, and
REMANDED for further proceedings consistent with this decision.
