Can a U.S. Punitive Damages Judgment Be Enforced in South Korea?

1. What Is the Supreme Court of Korea’s Standard for Enforcing Foreign Punitive Damages Judgments in South Korea?

The controlling authority is the Supreme Court of Korea, Case No. 2018Da231550, decided March 11, 2022. This decision established the “regulated domain” (규율 영역) standard, which all lower courts now apply when a foreign punitive damages judgment is presented for enforcement in South Korea.

The Regulated Domain Standard

The Supreme Court held that where a foreign judgment awards damages beyond actual compensation, the critical question is whether the conduct that gave rise to the foreign judgment falls within an area of Korean domestic law that already authorizes punitive-style damages. If the conduct would be regulated by such a statute in South Korea, enforcing the foreign judgment does not fundamentally contradict Korea’s damages law principles — even if the specific multiplier or calculation method differs.

The Court identified three factors courts must weigh on a case-by-case basis.

The Court also clarified that the mere fact a foreign law automatically multiplies damages by a fixed factor — without the court exercising individual discretion — does not, by itself, justify refusing enforcement. Courts may consider the applicable Korean statutory cap to calibrate the outcome, but they may not re-examine whether the award was substantively correct.

The Prohibition on Re-Examination of Merits

Article 27(1) of the Civil Execution Act of South Korea states that an enforcement judgment shall be issued without examining whether the foreign judgment is correct. This no-review principle operates independently of the regulated domain analysis. Even if a Korean court considers a foreign damages award excessive, it may not substitute its own assessment of the appropriate compensation (Seoul High Court, Case No. 2024Na2003631, September 25, 2024, citing Supreme Court Case No. 2015Da1284, October 15, 2015).

2. What Are the Legal Requirements for Enforcing a Foreign Judgment in South Korea?

A foreign judgment cannot be directly enforced in South Korea. The judgment creditor must first obtain an enforcement judgment (집행판결) from a Korean court. This is a separate domestic lawsuit in which the court verifies — but does not re-litigate — the foreign proceeding.

Four Requirements Under Article 217(1) of the Civil Procedure Act

For damages judgments specifically, Article 217-2(1) of the Civil Procedure Act adds a further layer: the court may refuse to recognize a foreign damages judgment — in whole or in part — if recognition would produce a result fundamentally contrary to the basic order of Korean law or treaties to which Korea is a party. Under the regulated domain standard, this provision is the primary vehicle for challenging punitive damages enforcement.

Note that Article 217-2(1) applies only to damages that exceed actual compensation. Where a foreign judgment awards purely compensatory damages, this provision cannot be invoked to block enforcement, even if the dollar amount appears disproportionate by Korean standards (Seoul High Court, Case No. 2024Na2003631).

3. Case Study: Product Liability — How Did South Korea’s Court Handle a USD 33.9 Million Florida Judgment?

Seoul High Court, Case No. 2024Na2003631 (decided September 25, 2024) is the most recent and arguably most significant example of a Korean court enforcing a large U.S. damages judgment against a Korean manufacturer.

Background

Company B, a Korean manufacturer of packaging and plastic molding equipment, exported a hole-punching machine to Company C, located in Florida. Company B dispatched its own engineers to assemble and install the machine at C’s factory. In July 2013, Plaintiff A — a worker at C’s facility — suffered a wrist amputation when her hand was drawn into the machine.

Plaintiff A filed suit in 2017 before the Circuit Court of the Eleventh Judicial Circuit in and for Miami-Dade County, Florida (Case No. 2017-015183-CA-01). Company B received the complaint through judicial assistance under the Hague Service Convention but filed no answer. The case proceeded as a Default Judgment. Notwithstanding the default posture, the court empaneled a jury, which determined damages as follows.

The Korean Enforcement Proceeding

Plaintiff A subsequently filed for an enforcement judgment in South Korea, seeking execution up to USD 900,000. The court of first instance dismissed the suit. The Seoul High Court reversed, granting enforcement.

On international jurisdiction, the Seoul High Court found that Florida courts had proper jurisdiction for the following reasons: the injury occurred in Florida; Company B had not merely exported the machine but dispatched engineers to assemble and install it on-site; Company B had participated in Florida trade exhibitions since 2012 and continuously exported products to the United States, including parts to Company C after the accident; and a manufacturer of potentially dangerous machinery could reasonably foresee being sued in the jurisdiction where the injury occurred (citing Supreme Court of Korea, Case No. 2012Da21737, February 12, 2015).

On proper service, the Seoul High Court confirmed that the complaint had been validly served through s法공조 under the Hague Convention on the Service Abroad of Judicial and Extrajudicial Documents (Seoul High Court, citing Supreme Court of Korea, Case No. 2017Da257746, December 23, 2021). The judgment was also confirmed as final under Florida Rules of Appellate Procedure rule 9.110(b).

On public policy and Article 217-2(1), the court held that this case involved product liability — an area where South Korea’s own Product Liability Act (Article 3(2)) authorizes damages of up to three times actual harm when a manufacturer knowingly fails to act on a known defect causing serious bodily injury. Accordingly, enforcing the U.S. judgment did not produce a result fundamentally contrary to South Korea’s damages law principles (citing Supreme Court of Korea, Case No. 2018Da231550). The court also explicitly rejected Company B’s argument that the damages were excessive, holding that substituting the Korean court’s own damages calculation would violate the no-review principle.

4. Case Study: Unfair Competition — How Were 3x Treble Damages Enforced in South Korea?

Seoul High Court, Case No. 2022Na2011874 (decided September 22, 2022) is the post-remand ruling in the case that reached the Supreme Court as Case No. 2018Da231550. It is the most detailed application of the regulated domain standard to a treble-damages award.

Background

Plaintiffs A and B held an exclusive distribution agreement with Philippine food company D, under which they imported and sold dried mango products in Hawaii and across the Pacific. Defendant C tortiously interfered with this exclusive arrangement and employed unfair competitive practices to drive A and B out of the market. Plaintiffs filed suit in the Circuit Court of the First Circuit of the State of Hawaii (Case No. Civil 09-1-0351 (ECN)).

A jury found for the plaintiffs. The presiding judge then applied Hawaii Revised Statutes § 480-13(b)(1), which mandates trebling of damages for unfair or deceptive trade practices, yielding the following final award.

Defendant C appealed within Hawaii. The Hawaii Intermediate Court of Appeals dismissed the appeal in November 2015. The Hawaii Supreme Court denied certiorari in March 2016, making the judgment final.

The Korean Proceedings and the Supreme Court Remand

Plaintiffs filed for an enforcement judgment in South Korea. The Seoul High Court in its initial ruling (March 23, 2018) restricted enforcement to the compensatory portion, excluding the punitive increment. Plaintiffs appealed to the Supreme Court. The Supreme Court reversed in Case No. 2018Da231550 (March 11, 2022), establishing the regulated domain standard and holding that Hawaii’s treble damages award could not be blocked simply because Korean law did not have an identical statute.

On remand, the Seoul High Court granted enforcement of the full treble-damages award. The court applied the regulated domain analysis: Defendant C’s conduct — tortious interference with an exclusive distribution agreement through unfair competitive practices — would constitute an unfair trade practice under the Korean Fair Trade Act (Act on Monopoly Regulation and Fair Trade, Article 45). Although the Fair Trade Act does not specifically authorize treble damages for that precise category of unfair trade practice, it does authorize triple damages for cartel conduct and similar violations within the same statutory framework. That was sufficient to bring the case within the regulated domain. The court also rejected the argument that enforcement should be limited to whatever a Korean court would hypothetically have awarded — doing so would constitute a prohibited review of the merits.

5. Which Areas of Korean Law Already Allow Punitive Damages in South Korea?

The regulated domain analysis depends directly on whether the relevant area of Korean law has adopted punitive-style damages. South Korea introduced its first such provision in 2011 under the Subcontracting Act and has been expanding coverage steadily. The current landscape is as follows.

Statutes Authorizing Up to 3x Damages

Statutes Authorizing Up to 5x or More

As these regulated domains expand, the category of foreign punitive damages judgments that can be blocked on public policy grounds narrows correspondingly. The practical result: a foreign judgment awarding treble damages for conduct that South Korea now treats as worthy of punitive sanction will very likely be enforced.

6. What Do These Decisions Mean for Foreign Companies and Korean Exporters?

For foreign plaintiffs holding a U.S. or other common-law punitive damages judgment against a Korean defendant, the 2022 Supreme Court ruling and subsequent Seoul High Court decisions substantially improve the enforcement outlook. Key considerations are whether the underlying conduct maps onto a regulated domain under Korean law, and whether the multiplier applied by the foreign court is within the range Korean law would recognize for comparable conduct.

For Korean companies that export products, license technology, or distribute goods abroad, the lesson is structural. The cases examined in this article share a common thread: Korean defendants failed to engage with foreign proceedings at all. In the product liability case, the company received proper service through the Hague Convention and still filed no answer. The result was a default judgment of USD 33.9 million — and a Korean court that then declined to substitute its own damages assessment. Litigation strategy, dispute resolution clauses in contracts (choice of law, forum selection), and early engagement with experienced Korean counsel when a foreign complaint is received are no longer optional risk-management considerations.
