## Facts

- Banco Ambrosiano, S.p.A. (an Italian bank) sued Artoc Bank & Trust Ltd. (a Bahamian bank) to recover $15 million allegedly loaned in three $5 million transactions.
- Artoc maintained a correspondent account in New York at Brown Brothers Harriman & Co.; neither bank was authorized to conduct banking business in New York.
- Artoc’s internal memoranda indicated Ambrosiano would deposit the loan proceeds into Artoc’s New York correspondent account and that repayment would be made to Ambrosiano’s New York correspondent account.
- Artoc did not dispute receipt of the $15 million but denied an unconditional repayment obligation, asserting the funds were intended to be relent to an Ambrosiano-controlled Peruvian subsidiary and that Artoc would repay only if and when the ultimate recipient repaid.
- Negotiations and communications occurred outside New York (Italy, the Bahamas, and Peru); the New York connection consisted of the use of New York accounts to receive, route, and repay the funds.
- Ambrosiano commenced the action in New York Supreme Court by attaching approximately $8 million in Artoc’s New York correspondent account; the trial court confirmed the attachment on a quasi-in-rem theory.
- The Appellate Division affirmed; the Court of Appeals reviewed whether the attachment-based jurisdiction satisfied due process.

## Issues

1. Whether due process permits New York to exercise quasi-in-rem jurisdiction over a foreign bank by attaching funds in its New York correspondent account when the account was used to effectuate the disputed loan transactions and the defendant lacked other New York contacts.

## Decision

- The Court of Appeals affirmed the order confirming attachment and upheld the exercise of quasi-in-rem jurisdiction.
- The court held that the contacts among the defendant, New York, and the litigation were sufficient to satisfy due process.
- The court emphasized that the attached property (the New York correspondent account) was directly connected to the loan transactions at issue because it was the designated conduit for disbursement and contemplated repayment.

## Legal Principles

- All assertions of state-court jurisdiction, including quasi-in-rem jurisdiction based on property, must satisfy due process “minimum contacts” requirements.
- For quasi-in-rem jurisdiction based on attached property, the property’s presence in the forum must bear a meaningful relationship to the underlying claim, assessed through the nexus among the defendant, the forum, and the litigation.
- A foreign bank’s deliberate use of New York correspondent banking facilities to execute the specific disputed transactions can constitute purposeful forum contact supporting a limited, attachment-based jurisdiction consistent with fair play and substantial justice.

## Conclusion

New York could constitutionally exercise quasi-in-rem jurisdiction by attaching a foreign bank’s New York correspondent account where the account was purposefully used as the mechanism to receive and repay the loan proceeds that formed the basis of the suit, even though negotiations occurred abroad and the defendant was not otherwise subject to in personam jurisdiction in New York.
