of his trespass claim, grant of summary judgment to Defendants on his nuisance
claims, decertification of the Ground and Air Subclasses, and denial of the motion
to substitute Navarro as class representative. We have jurisdiction 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
denial of the motion to substitute Navarro as class representative for 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
2 23-3274
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”
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.
2. We review the district court’s class decertification order and denial of the
motion to substitute Navarro as class representative for abuse of discretion. See
Castillo v. Bank of Am., NA, 980 F.3d 723, 728 (9th Cir. 2020). The district court
3 23-3274
abused its discretion in reaching its conclusions that Navarro and his counsel
would not fairly and adequately protect the interests of the class as required under
Federal Rule of Civil Procedure 23(a)(4) and that Navarro’s trespass claim was not
typical of the class as required under Federal Rule of Civil Procedure 23(b)(3).
As to Navarro’s adequacy to serve as class representative, Navarro’s
testimony indicated that he was legitimately concerned about the alleged
contamination and that he was reasonably involved in and informed about the
litigation. The district court did not consider Navarro’s testimony that he was
concerned about health impacts from petroleum in the ground at his property or
that he regularly met with counsel and was aware of relevant litigation documents.
And, in concluding that counsel was inadequate, the district court did not consider
the large volume of competent work completed by counsel over years of litigation.
See Sali v. Corona Reg’l Med. Ctr., 909 F.3d 996, 1008 (9th Cir. 2018) (holding
that district court abused its discretion in finding that class counsel was inadequate
after discussing only counsel’s errors and not the record evidence demonstrating
counsel’s competent work).
As to the typicality of Navarro’s trespass claim, the district court erred by
relying on its determination that Navarro would not consider a remedy that
involved selling his home. Although the record indicates that Navarro had not
previously considered selling his home, it does not show that Navarro would be
4 23-3274
unwilling to accept relocation as a remedy. And, in any event, there is no
indication in the record that any class members sought relocation as a possible
remedy. See Cummings v. Connell, 316 F.3d 886 (9th Cir. 2003) (“[T]his circuit
does not favor denial of class certification on the basis of speculative conflicts.”).
The district court’s remaining reasons for denying the motion to substitute
and decertifying the Ground Subclass (including the court’s other reasons for
concluding that typicality was not satisfied and the court’s conclusions regarding
the commonality and Rule 23(b)(3) requirements) were predicated on the court’s
narrow construction of Navarro’s and other class members’ trespass claims. The
denial of the motion to substitute Navarro as class representative and the
decertification of the Ground Subclass are therefore vacated and remanded for
reconsideration under the broader trespass theory that includes soil and
groundwater contamination.
3. 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
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)).
5 23-3274
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
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.
