Background

Shenzhen Zehuijin Investment Center loaned Liu Yingkui 160 million Chinese yuan in 2017. After Liu failed to repay the loan, the Beijing Arbitration Commission entered an award of approximately 150 million yuan against him, and a Singapore court later ordered him to pay it. Liu did not pay.

The Investment Center petitioned the Southern District of California to confirm the award under Chapter 2 of the Federal Arbitration Act, which implements the New York Convention. After two unsuccessful attempts to hand Liu the papers at his California residence, a process server left them with an adult who identified herself as a cotenant, mailed them to the residence, and emailed them to Liu. Liu, who admitted living at that address for approximately two years and receiving actual notice, moved to dismiss for lack of personal jurisdiction but did not assert insufficient service under Federal Rule of Civil Procedure 12(b)(5). The district court confirmed the award and entered judgment against him.

The Court’s Holding

The Ninth Circuit affirmed, holding that the Fourteenth Amendment does not require process to be handed directly to a defendant for a court to exercise presence-based general personal jurisdiction. Because Liu was voluntarily and continuously physically present in California when he was served by means reasonably calculated to provide—and which did provide—actual notice, the district court had general jurisdiction over him even though the underlying loan and arbitration arose outside California.

The court separately declined to decide whether the Investment Center strictly or substantially complied with applicable substitute-service rules. Insufficient service under Rule 12(b)(5) is a distinct defense from lack of personal jurisdiction under Rule 12(b)(2), and Liu waived it by omitting it from his motion to dismiss. The panel added that, even if Liu had preserved a constitutional objection to notice, he offered no reason why the service used here failed due process.

Key Takeaways

  • A natural person’s voluntary physical presence in the forum can support general personal jurisdiction even when the claims are unrelated to that forum.
  • Presence-based jurisdiction does not constitutionally depend on papers being handed directly to the defendant; other means of service may suffice.
  • Lack of personal jurisdiction and insufficient service of process are separate Rule 12 defenses, and a defendant who omits the service defense from a motion to dismiss may waive it.

Why It Matters

The decision clarifies that “tag” or presence-based jurisdiction turns on the defendant’s voluntary physical presence in the forum, not exclusively on in-hand service. It therefore permits courts to exercise general jurisdiction when a physically present defendant receives process through another constitutionally adequate method.

The ruling also underscores a procedural trap: defendants must separately preserve objections to personal jurisdiction and to the manner of service. Raising only Rule 12(b)(2) will not necessarily preserve a Rule 12(b)(5) challenge, including in proceedings to enforce foreign arbitral awards.
