In Monteverde v. Harpoon, Judge Martinez-Olguin granted remand because Harpoon did not show federal jurisdiction was proper.
Monteverde & Associates PC and Harpoon Therapeutics, Inc.; the case was sent back to San Mateo Superior Court, and the federal court’s pending deadlines and hearings were vacated.
What happened
In Monteverde & Associates PC v. Harpoon Therapeutics, Inc., Monteverde asked the federal court to return the case to San Mateo Superior Court. The dispute involved state-law claims concerning disclosures in an original proxy statement and supplemental disclosures.
Harpoon argued that the state-law claims raised a substantial federal issue that allowed the federal court to hear them. The court rejected that argument, finding that the federal questions depended on the specific disclosures and circumstances in this case and therefore were fact-bound rather than substantial.
Judge Araceli Martinez-Olguin ruled that federal subject-matter jurisdiction was lacking and granted Monteverde’s motion to remand. The clerk was directed to send the case back to state court, and all deadlines and hearings set in federal court were vacated.

Background
Monteverde & Associates PC moved to remand, meaning to return, the case to San Mateo Superior Court. The motion was directed at the federal court’s jurisdiction over the matter. The opinion identifies the relevant claims as state-law claims involving whether Harpoon had to disclose omitted information in the original proxy statement, whether that statement was misleading, and whether supplemental disclosures were material.
Arguments and legal standard
Harpoon had the burden of showing that removal to federal court was proper. It argued that the state-law claims necessarily raised a federal issue that was actually disputed and substantial, allowing federal jurisdiction under the doctrine discussed in Grable & Sons Metal Products, Inc. v. Darue Engineering & Manufacturing.
The court explained that a federal question is not substantial when it is fact-bound and situation-specific or presents only a hypothetical question unlikely to affect future interpretations of federal law. The court applied that standard to the questions raised by Monteverde’s claims.
Court’s analysis
The court found that resolving the federal questions would require examining the particular disclosures and circumstances involved in this case. It therefore characterized those questions as fact-bound and situation-specific. Because Harpoon had not shown that the federal issues were substantial, the court concluded that it lacked subject-matter jurisdiction.
Disposition
The court granted Monteverde’s motion to remand under 28 U.S.C. § 1447(c). The clerk was directed to transmit the case file back to the state court. The court also vacated all pending deadlines and hearings scheduled before it.
