Trial Court Opinion

4 UNITED STATES DISTRICT COURT 5 NORTHERN DISTRICT OF CALIFORNIA THOMAS LANGENDERFER,1 Case No. 24-cv-06526-HSG 8 Plaintiff, ORDER GRANTING MOTION TO DISMISS 9 v. Re: Dkt. No. 44 10 ROGER A. MILLER, et al., 11 Defendants.

13 Pending before the Court is Defendants’ second motion to dismiss. Dkt. No. 44. The Court finds this matter appropriate for disposition without oral argument and the matter is deemed submitted. See Civil L.R. 7-1(b). For the reasons detailed below, the Court GRANTS the motion.

16 I. BACKGROUND 17 Pro se Plaintiff Geronimo Thomas Langenderfer filed this case in September 2024 against Defendants Thomas J. Madden, Nicholas Lumbreras, and Roger A. Miller, seeking approximately $8 million for breach of contract. See Dkt. No. 1. On April 16, 2025, the Court granted Defendants’ motion to dismiss for lack of subject matter jurisdiction under Federal Rule of Civil Procedure 12(b)(1). Dkt. No. 39. The Court concluded that Plaintiff failed to establish that the Court has subject matter jurisdiction. See id. The Court accordingly directed Plaintiff to file an amended complaint that “clearly explains what federal question is raised by his claim against Defendants.” See id. at 4. The Court cautioned Plaintiff that if he could not do so then his case would be dismissed without prejudice to refiling in state court. Id. The case caption is automatically generated by the Clerk’s Office based on how the complaint is 1 Plaintiff filed an untimely amended complaint on June 16, 2025. Dkt. No. 43 (“FAC”).

2 Defendants move to dismiss under Rule 12(b)(1). Dkt. No. 44. As before, Defendants argue that Plaintiff has failed to establish subject matter jurisdiction. Id. II. LEGAL STANDARD 5 Under Federal Rule of Civil Procedure 12(b)(1), a party may move to dismiss based on the court’s lack of subject matter jurisdiction. See Fed. R. Civ. P. 12(b)(1). “Federal courts are courts of limited jurisdiction,” and “[t]hey possess only that power authorized by Constitution and statute.” Kokkonen v. Guardian Life Ins. Co. of Am., 511 U.S. 375, 377 (1994). “Subject matter jurisdiction can never be forfeited or waived and federal courts have a continuing independent obligation to determine whether subject matter jurisdiction exists.” See Leeson v. Transam.

11 Disability Income Plan, 671 F.3d 969, 975, n.12 (9th Cir. 2012) (quotation omitted). The party invoking subject matter jurisdiction has the burden of establishing that such jurisdiction exists.

13 See Lujan v. Defs. of Wildlife, 504 U.S. 555, 561 (1992).

14 III. DISCUSSION 15 Much like the initial complaint, the FAC is difficult to follow. Plaintiff still appears to bring a breach of contract claim against Defendants. See, e.g., FAC at 4, 9. In the FAC and in his opposition brief, Plaintiff asserts that the Court has subject matter jurisdiction because this case involves a federal question under 28 U.S.C. § 1331. See generally FAC; see also Dkt. No. 47.

19 But critically, and despite the Court’s direction, Plaintiff still does not identify this federal question with any level of specificity.

21 Federal district courts have original jurisdiction over all civil actions “arising under the Constitution, laws, or treaties of the United States.” See 28 U.S.C. § 1331. Such jurisdiction “exists only when a federal question is presented on the face of the plaintiff’s properly pleaded complaint.” Caterpillar Inc. v. Williams, 482 U.S. 386, 392 (1987). Thus, a case may “aris[e] under” federal law for the purpose of 28 U.S.C. § 1331 “when federal law creates the cause of action asserted.” Gunn v. Minton, 568 U.S. 251, 257 (2013). The Supreme Court has recognized that in rare cases, a case may also “arise under” federal law where it “implicate[s] significant (2005). Under Grable, a federal court may exercise jurisdiction over a state law claim only if (1) the action necessarily raises a federal issue that is (2) actually disputed, (3) substantial, and (4) capable of resolution in federal court without disrupting the federal-state balance approved by Congress. Id. at 313–14.

5 Plaintiff recites this case law in his papers, but does not offer any substantive explanation of how it applies to his case. As the Court already explained in its prior order, Plaintiff’s breach of contract claim does not arise under federal law. See Dkt. No. 39 at 2–3. As best the Court can discern, Plaintiff believes that federal law is somehow implicated by the underlying cannabis contract at issue in this case. See FAC at 3. Plaintiff refers to himself as a “federal contractor,” and suggests that he and Defendants entered into a “government contract.” See id. at 4–5, 9; see also Dkt. No. 47 (referencing a “Presidential Contract”). But Plaintiff’s unsupported assertion that this case implicates a government contract is not sufficient to support jurisdiction. Plaintiff urges the Court to consider the exhibits he attaches to the FAC, but they do not provide any clarity.

14 Although some of the documents reference “federal licenses,” it is still not clear why resolution of the breach of contract claim in this case would raise a substantial federal issue or require consideration of any federal law. Plaintiff vaguely asserts that his claim “will set a precedence” [sic]. See Dkt. No. 47 at 6. This is not enough. Even liberally construing the FAC, it is simply not clear what Plaintiff means by this.

19 To the extent Plaintiff suggests that a federal question is presented on the face of the complaint because he is affiliated with a tribal government, Dkt. No. 47 at 6–7, the Court previously rejected this argument. See Dkt. No. 39 at 3–4. The Ninth Circuit has explained that “federal question jurisdiction does not exist simply because an Indian tribe or individual is a party.” Newtok Vill. v. Patrick, 21 F.4th 608, 616 (9th Cir. 2021). “Nor is there any general federal common law of Indian affairs.” Id. (quotation omitted). Again, this appears to be a contract dispute that will require consideration of state law rather than the resolution of any federal issue. Plaintiff bears the burden of establishing that the Court has subject matter jurisdiction, and once again he has failed to do so.

1 IV. CONCLUSION 2 The Court GRANTS the motion to dismiss. Dkt. No. 44. At this point, Plaintiff has had ample opportunity to amend the complaint and has failed to establish that the Court has subject || matter jurisdiction. The Court therefore DISMISSES the case against Defendants without leave to amend and without prejudice to refiling in state court. See Ramirez v. Galaza, 334 F.3d 850, || 860 (9th Cir. 2003) (“Leave to amend should be granted unless the pleading could not possibly be cured by the allegation of other facts, and should be granted more liberally to pro se plaintiffs.”’)
