Background

Sergay Firsov pursued federal and state claims against United Airlines arising from international air travel. After earlier opportunities to amend, United again argued that the complaint did not state a viable claim under the Montreal Convention.

The ruling addresses the dispute at its current procedural stage and does not resolve issues the court expressly left for later proceedings.

The Court’s Holding

The court dismissed the Convention claims with prejudice because repeated amendments did not cure the identified deficiencies. It declined supplemental jurisdiction over the remaining state-law claims and dismissed those without prejudice, leaving Firsov free to pursue them in state court subject to an existing prefiling order.

The result follows from the governing pleading, jurisdictional, or merits standard applied to the record before the court.

Key Takeaways

  • International-air-travel disputes require careful alignment with the Montreal Convention’s liability categories and conditions.
  • Once the federal theory drops out, related state claims may have to restart in state court, adding limitations and prefiling issues.
  • Practitioners should preserve the documents and technical evidence needed to prove the rule applies to the client’s specific facts.

Why It Matters

International-air-travel disputes require careful alignment with the Montreal Convention’s liability categories and conditions. Once the federal theory drops out, related state claims may have to restart in state court, adding limitations and prefiling issues.

The decision is unreported and may be persuasive rather than binding, but it offers a current view of how a Northern District of California judge is applying these rules.
