Background

Takuya Debun and his former spouse, Kairi Debun (also identified in the petition as Kairi Futami), are Japanese nationals. According to the petition, Kairi and their daughter, H.D., traveled from Japan to join Debun in Cupertino, California, in July 2023, and shortly afterward Kairi removed H.D. to Japan without his consent. Debun sought H.D.'s return in the Japanese courts under the Hague Convention on the Civil Aspects of International Child Abduction. The Tokyo Family Court dismissed his application and held that H.D.'s habitual residence was Japan, and the Tokyo High Court dismissed his appeal. Debun did not seek review in the Supreme Court of Japan and represents that the Japanese determination is now final.

Debun also filed petitions under the International Child Abduction Remedies Act (ICARA) in Santa Clara County Superior Court and in the Northern District of California. The petition alleges that the Superior Court denied its petition for lack of jurisdiction and that the denial is on appeal. In federal court, his Second Amended Verified Petition pleaded two counts. Count One sought an order under ICARA section 9003 requiring H.D.'s return to the United States. Count Two sought, in the alternative, a determination under article 15 of the Convention that the removal was wrongful. After the Court ordered him to show cause why the petition presented cognizable claims, Debun conceded that Count One was not cognizable and asked for its dismissal without prejudice, but maintained that Count Two, the relief he principally seeks, was cognizable.

The Court’s Holding

The Court construed Debun's request as a motion for voluntary dismissal under Federal Rule of Civil Procedure 41(a)(2) and granted it. It found that Kairi would suffer no legal prejudice, because dismissal without prejudice returns the parties to the position before the petition was filed and does not deprive her of a federal forum, a jury trial, or a limitations defense. The Court also observed that Debun accepts he has no claim under section 9003 here, because that provision allows a judicial remedy only in a court exercising jurisdiction where the child is located, and H.D. is in Japan.

The Court dismissed Count Two for lack of subject matter jurisdiction under Rule 12(h)(3), raising standing on its own initiative. It did not decide whether an individual parent may seek an article 15 determination without a request from a judicial or administrative authority. Instead, it held that Debun had not carried his burden on redressability. Even assuming injury and traceability, neither the petition nor his response identified a predictable chain of events connecting a declaration of wrongful removal to H.D.'s return. Debun acknowledged that the declaration would not bind Japanese authorities, which had already denied his application. A declaration alone is not redress, and his references to possible further proceedings and pending requests to the Executive Branch and Members of Congress were too speculative.

The Court denied further leave to amend as futile, noting that Debun had already amended twice and that the Japanese determination is final. The petition was dismissed in its entirety without leave to amend and without prejudice. A footnote cautions that re-filing the same claims on the same facts would also be dismissed.

Key Takeaways

  • A claim for declaratory relief must still satisfy Article III redressability, and a declaration is not itself redress.
  • A declaration that would not bind authorities in the child's country of residence, after a final adverse ruling there, does not show a predictable chain to the child's return.
  • Vague references to possible future proceedings or appeals to the political branches are too speculative to establish standing.
  • A Rule 41(a)(2) dismissal without prejudice is appropriate when the opposing party shows no legal prejudice.
  • The Court left open whether a parent may seek an article 15 determination without a request from a judicial or administrative authority.

Why It Matters

This is a district court order, not a published appellate opinion, so it carries persuasive weight only. It shows that a Hague wrongfulness declaration cannot supply jurisdiction when it would not realistically lead to the child's return.

The order resolves only standing and voluntary dismissal. It does not decide the wrongful-removal allegations on the merits or the scope of article 15, and the state-court appeal described in the petition is not addressed.
