Appeal from the United States District Court for the District of Montana Dana L. Christensen, District Judge, Presiding

Argued and Submitted April 13, 2026 Portland, Oregon

Before: OWENS, VANDYKE, and SUNG, Circuit Judges.

Plaintiffs-Appellants are children and young adults who challenge three

3 25-6714 executive orders signed by President Trump (collectively, the “Executive Orders”)

that set several broad directives for federal energy policy and direct agencies to

implement those directives “in a manner consistent with applicable law.” See Exec.

Order No. 14154, 90 Fed. Reg. 8353, 8359 (Jan. 20, 2025); Exec. Order No. 14156,

90 Fed. Reg. 8433, 8437 (Jan. 20, 2025); Exec. Order No. 14261, 90 Fed. Reg.

15517, 15519 (Apr. 8, 2025). Plaintiffs appeal the district court’s dismissal of their

complaint for lack of Article III standing and the district court’s denial of leave to

amend their complaint.

We review de novo the district court’s dismissal for lack of Article III

standing, Satanic Temple v. Labrador, 149 F.4th 1047, 1050 (9th Cir. 2025), and

review for abuse of discretion the district court’s denial of leave to amend, Ass’n des

Eleveurs de Canards et d’Oies du Quebec v. Bonta, 33 F.4th 1107, 1113 (9th Cir.

2022). We have jurisdiction under 28 U.S.C. § 1291, and we affirm.

1. Plaintiffs have not plausibly alleged that their asserted injuries are “caused

by the challenged” Executive Orders. Juliana v. United States, 947 F.3d 1159, 1168

(9th Cir. 2020).1 According to the complaint, Plaintiffs will be harmed by numerous

agency actions which, Plaintiffs allege, will “implement” the Executive Orders over

several years. But Plaintiffs can only speculate that the Executive Orders are the

1 We do not reach whether Plaintiffs’ asserted injuries satisfy Article III’s injury-in- fact requirement.

4 25-6714 cause of the many agency actions they allege will exacerbate climate change. See

G.B. ex rel. G.P. v. EPA, 172 F.4th 1042, 1060 (9th Cir. 2026) (“[A]gencies consider

a great number of … factors in determining when, what, and how to regulate or take

agency action.” (citation modified)); Clapper v. Amnesty Int’l USA, 568 U.S. 398,

412–14 (2013) (rejecting traceability theory premised on speculation that

government surveillance would occur, if at all, under challenged authority rather

than another). Furthermore, Plaintiffs seek to enjoin any “implementing” agency

action, including those not identified in the complaint. But we “cannot presume to

predict how governing officials might exercise their discretion.” G.B., 172 F.4th at

1059 (citation modified). Whether agencies will rely on the Executive Orders when

taking future action “is mere conjecture.” Id. at 1061 (citation modified). For these

reasons, the link between the Executive Orders and Plaintiffs’ alleged injuries is too

speculative to support Article III standing. See FDA v. All. for Hippocratic Med.,

602 U.S. 367, 383 (2024); G.B., 172 F.4th at 1058–62.

2. Plaintiffs’ requested injunctive relief is also neither “substantially likely to

redress their injuries” nor “within the district court’s power to award.” Juliana, 947

F.3d at 1170 (citation omitted).

As to the first redressability prong, Plaintiffs’ standing theory suffers from a

defect that mirrors their traceability problems. See All. for Hippocratic Med., 602

U.S. at 380–81 (noting that “causation and redressability … are often flip sides of

5 25-6714 the same coin” (citation modified)). They have not plausibly alleged that enjoining

federal agencies from implementing the Executive Orders is substantially likely to

prevent agencies from taking similar emissions-inducing actions under other lawful

authorities.

Second, as in Juliana, Article III does not give federal courts the power to

grant or enforce the injunctive relief Plaintiffs seek. Juliana, 947 F.3d at 1171. The

Executive Orders state the President’s national security, energy, and economic

policy in broad terms, then direct executive branch agencies to pursue these policy

goals consistent with applicable law. Plaintiffs’ requested injunction, by its terms,
