A construction equipment operator causes an on-site accident that injures a co-worker. South Korea’s national workers’ compensation insurer — COMWEL — pays out benefits and then turns to the equipment operator seeking reimbursement. Can it? Under a landmark 2026 en banc ruling, the answer is generally no.
South Korea’s Supreme Court sitting en banc held on January 22, 2026 that a construction equipment lessor who operates equipment under the direction and command of the site owner shares the same workplace risk as the injured worker. As a result, the lessor does not qualify as a “third party” under Article 87(1) of the Industrial Accident Compensation Insurance Act (IACIA), and COMWEL cannot subrogate the injured worker’s tort claim against the lessor (Supreme Court 2022Da214040). A follow-up ruling on April 2, 2026 applied this standard to an excavator operator and reached the same conclusion (Supreme Court 2022Da250008).
These two rulings are significant for construction, logistics, and manufacturing companies operating in South Korea. They settle a long-contested question about when COMWEL’s subrogation rights extend to on-site equipment operators — and they overturn a line of Supreme Court decisions stretching back to 2008. The new “shared risk” standard cuts across formal contract labels, applying regardless of whether the operator is classified as an employee, subcontractor, or independent lessor.
What Does the Statute Say? — IACIA Article 87
The controlling statute is Article 87 of the Industrial Accident Compensation Insurance Act (산업재해보상보험법). At the time of the en banc case, the version in force was the pre-May 26, 2020 amendment, but the current text is materially identical.
① Where COMWEL pays insurance benefits for an occupational accident caused by the act of a third party, COMWEL is subrogated to the recipient’s tort claim against the third party up to the amount of benefits paid. Provided, however, that where two or more employers who are policyholders jointly operate one project at the same site by dividing it among themselves, and an accident is caused by a worker of a different employer, this shall not apply. <Amended May 26, 2020>
② Where the benefit recipient has received compensation from the third party for the same cause equivalent to COMWEL benefits, COMWEL shall not pay benefits up to the amount calculated by converting that compensation pursuant to Presidential Decree.
③ Recipients and policyholders shall promptly notify COMWEL when an occupational accident is caused by a third party’s act.
The provision has two parts. The main clause grants COMWEL subrogation rights against “third parties.” The proviso carves out cases where two policyholder-employers share one project at the same site. The en banc court held that both the main clause and the proviso must be interpreted under a single unified standard: whether the parties shared the same workplace risk.
Two Rulings, One Legal Question — How Do They Relate?
Both cases ask the same question: does a construction equipment lessor who provides both the machine and an operator under a combined lease-and-labor contract qualify as a “third party” subject to COMWEL subrogation? The two rulings are connected as follows.
| Parties | X (COMWEL) vs. A (forklift driver), B (equipment lessor, A’s employer) |
|---|---|
| Site Owner | C (subcontractor) |
| Injured Worker | D |
| Lower Court | Daegu District Court, Jan. 13, 2022 (2021Na311355) |
| Significance | Overturned prior precedents (2006Da32910 etc.). Established “shared risk” standard. Separate concurrence by two justices. |
| Parties | X (COMWEL) vs. E (excavator operator and lessor) |
|---|---|
| Site Owner | F (general contractor) |
| Injured Worker | G |
| Lower Court | Busan District Court, Jun. 9, 2022 (2021Na62737) |
| Significance | First division ruling applying en banc standard to excavator lessor. COMWEL’s claim dismissed. |
Case 1 — What Happened in the Forklift Case?
B was an individual construction equipment lessor. B entered into a combined forklift lease and operator-labor contract with C, a subcontractor performing bridge construction work on a highway project. Under that contract, B’s employee A drove the forklift at C’s construction site under C’s direction and command.
On February 27, 2017 at 1:45 p.m., A was moving steel rebar bundles by forklift when D — a worker employed by C — approached beneath the forks to adjust a support block. A stopped the fork descent, but part of a rebar bundle fell and struck D’s head. D suffered severe cervical spinal cord injuries.
COMWEL (X) paid D medical benefits of KRW 267,889,990, temporary disability benefits of KRW 135,425,960, and disability annuity benefits (lump-sum equivalent KRW 233,552,722). X then filed a subrogation claim against A and B.
Lower Court: COMWEL Wins (Prior Standard Applied)
The Daegu District Court applied the pre-existing standard and found that A and B had no workers’ compensation insurance relationship with C and were therefore “third parties” subject to subrogation. COMWEL’s claim was upheld.
Supreme Court En Banc: COMWEL Loses (Prior Precedent Overturned)
The en banc court reversed and dismissed COMWEL’s claim. A had been working under C’s direction and command at C’s construction site, performing work that was incorporated into C’s bridge construction project. A and D shared the same workplace risk. Because they shared that risk, A and B were not “third parties” within the meaning of IACIA Article 87(1), and COMWEL could not subrogate D’s claim against them.
Case 2 — What Happened in the Excavator Case?
E was an individual construction equipment lessor who also personally operated the equipment. On February 26, 2018, E entered into a combined excavator lease and operator-labor contract with F, the general contractor for a complex demolition project in Haeundae, Busan. F assigned E the title “Technical Team Leader” and directed E to perform excavation work at specified times and locations.
On March 6, 2018 at 2:30 p.m., E was operating F’s excavator to demolish building columns using a hydraulic crusher when a piece of rebar flew off and struck G — an F employee who was resting on the 8th floor after completing scaffold removal work — on the left side of the face. G suffered a closed fracture of the left mandibular angle.
COMWEL (X) paid G temporary disability benefits of KRW 31,300,060, medical benefits of KRW 13,685,520, and disability benefits of KRW 33,017,900 (total KRW 78,003,480), then filed a subrogation claim against E.
Lower Court: COMWEL Wins (Prior Standard Applied)
The Busan District Court held that because E was not an employee of F under the Labor Standards Act, E was a “third party” and COMWEL’s subrogation claim was upheld.
Supreme Court: COMWEL Loses (En Banc Standard Applied)
The Supreme Court reversed, applying the en banc ruling directly. F had assigned E the title of Technical Team Leader and directed E’s work schedule and location. E’s excavation work and G’s scaffold removal work were both incorporated into and formed part of F’s demolition project. E and G shared the same workplace risk. Accordingly, E was not a “third party” and COMWEL could not subrogate G’s claim against E.
What Is the “Shared Risk” Standard?
The Core Principle
The scope of COMWEL’s subrogation right under IACIA Article 87(1) is determined not by who paid insurance premiums, but by whether the workers involved shared a common risk relationship with respect to occupational accidents at the same workplace (Supreme Court en banc 2022Da214040, January 22, 2026).
No Employment Contract Required
Even when the injuring party does not have an employment contract with the injured worker’s employer, if both parties performed work under the direction and command of the same employer, they share the risks inherent in that workplace. The reason: both parties’ work is incorporated into and forms part of the directing employer’s business.
Unified Standard for Main Clause and Proviso
Prior case law applied different tests to the main clause (insurance-relationship test) and the proviso (shared-risk test) of Article 87(1). The en banc court unified these into a single shared-risk inquiry. If the parties worked under the same employer’s direction, the injuring party falls outside the main clause’s “third party” definition. If the parties worked under different employers but shared one project at the same site, the proviso applies instead.
When the Standard Does Not Apply
The shared-risk exemption does not cover parties who are genuinely external to the workplace — for example, a driver delivering materials from an unrelated company, or a passerby. Such parties remain “third parties” against whom COMWEL may subrogate. Liability insurers also remain third parties regardless of this ruling.
Why Did South Korea’s Supreme Court Overturn Prior Precedent?
The Old Rule
Under decisions such as Supreme Court 2006Da32910 (April 10, 2008), construction equipment lessors were classified as “third parties” because they were neither employees of the site owner under the Labor Standards Act nor subcontractors, and therefore had no workers’ compensation insurance relationship with the injured worker. The insurance-relationship test was the controlling standard.
Why the Old Rule Was Rejected
The en banc court identified three core problems with the insurance-relationship test.
- It conflated the question of who pays premiums — a policy and legislative choice — with the question of who ultimately bears liability for a workplace accident, which is a substantive legal determination.
- It irrationally distinguished between equipment lessors and subcontractors, even though both work on the same site under the general contractor’s direction and both share the same physical risks.
- It effectively outsourced workplace risk: by allowing COMWEL subrogation against equipment operators, the old rule transferred the cost of inherent workplace accidents from the employer’s workers’ comp coverage to the individual operator — an outcome inconsistent with workers’ compensation insurance as a social insurance system.
The en banc ruling expressly overturned Supreme Court 2006Da32910, 2006Da27093, and 2006Da44760, along with all decisions to the same effect.
Practical Implications
For Construction Equipment Operators and Lessors
Equipment operators and lessors who work under a site owner’s direction and command — forklift drivers, excavator operators, crane operators, and similar — cannot be named as defendants in COMWEL subrogation claims for on-site accidents. This applies regardless of whether they are classified as employees, independent contractors, or sole proprietors under South Korean labor law.
End of the “Not an Employee” Defense for COMWEL
COMWEL can no longer argue that because an equipment operator is not an employee of the site owner under the Labor Standards Act, the operator is therefore a “third party.” The shared-risk standard replaces the employment-classification test entirely.
Summary Table
| Party’s Status | Third Party? | COMWEL Subrogation |
|---|---|---|
| Co-worker (same employer) | No | Not permitted |
| Subcontractor or subcontractor’s worker | No | Not permitted |
| Equipment lessor/operator under site owner’s direction (new rule) | No | Not permitted |
| Truly external party (no direction relationship) | Yes | Permitted |
| Liability insurer of equipment lessor | Yes | Permitted |
What Do Foreign Companies Operating in South Korea Need to Know?
For international businesses — whether joint ventures, wholly foreign-owned subsidiaries, or project companies operating in South Korea’s Incheon Free Economic Zone (IFEZ), which encompasses Songdo International Business District, Cheongna International City, and Yeongjong International City — this ruling has several practical takeaways.
Workers’ Comp Coverage Is the Final Line of Defense
Under the new shared-risk standard, COMWEL cannot recover paid workers’ comp benefits from equipment operators who work under your direction. This means your workers’ comp insurance policy — which all Korean employers must carry — bears the full cost of workplace accidents among all parties working under your direction, including equipment lessors. Ensure your coverage adequately reflects the full scope of on-site operations.
Different From Many Western Jurisdictions
In many common-law jurisdictions, an injured worker’s employer’s insurer may subrogate against a negligent independent contractor. South Korean law, as now clarified, takes a broader view of who shares a “common workplace risk,” limiting subrogation to parties who are truly external to the work organization. Foreign legal counsel should factor this into cross-border project risk assessments.
Liability Insurance for Equipment Remains Important
The en banc ruling expressly preserved COMWEL’s subrogation rights against liability insurers. Even though COMWEL cannot sue the equipment operator directly for reimbursement, it can still pursue the operator’s liability insurer. Foreign companies should confirm that equipment lessors carry adequate mandatory auto liability insurance and, where appropriate, general liability coverage.
Contract Drafting Considerations
South Korean law does not allow parties to contract out of workers’ compensation obligations. However, parties can allocate liability among themselves in separate indemnification agreements. When drafting combined equipment-lease and operator-labor contracts (건설기계 임대차 및 운전노무 제공 계약), Atlas Legal recommends including clear provisions on: (1) who bears the cost of workplace injury liability insurance beyond mandatory workers’ comp, (2) indemnification for third-party claims not covered by the shared-risk exemption, and (3) notice and cooperation obligations to COMWEL.
Frequently Asked Questions
Q. Who is a “third party” under Article 87(1) of South Korea’s IACIA?
A third party is someone who has no workers’ compensation insurance relationship with the injured worker and against whom COMWEL may subrogate the injured worker’s tort claim. The 2026 en banc ruling redefines this: the test is now whether the parties shared the same workplace risk, not whether they were linked through the premium-payment structure (Supreme Court 2022Da214040).
Q. Can COMWEL sue a construction equipment lessor for subrogation in South Korea?
Not if the lessor’s operator was working under the site owner’s direction and command. The Supreme Court en banc held that such operators share workplace risk with injured workers and are not “third parties” subject to COMWEL subrogation (Supreme Court 2022Da214040; affirmed in 2022Da250008).
Q. What is the “shared risk” standard established by South Korea’s Supreme Court?
Even if the injuring party has no formal employment contract with the site owner, if both the injuring party and the injured worker were performing work under the direction and command of the same employer, they share the risks inherent in that workplace. Their work is incorporated into and forms part of the employer’s business (Supreme Court en banc 2022Da214040).
Q. What legal standard did South Korean courts apply before this ruling?
Prior case law (e.g., Supreme Court 2006Da32910, April 10, 2008) held that construction equipment lessors were “third parties” because they were neither employees nor subcontractors of the site owner and thus had no workers’ comp insurance relationship with the injured worker. The en banc ruling explicitly overturned those decisions.
Q. Does this ruling apply to independent contractors, not just employees?
Yes. The Supreme Court expressly stated that the shared-risk standard applies regardless of whether the injuring party is an employee under the Labor Standards Act. The key question is direction and command by the same employer, not formal employment classification.
Q. Does this ruling affect liability insurance for construction equipment?
No. The en banc ruling expressly preserved COMWEL’s subrogation rights against liability insurers. The shared-risk exemption applies only to the equipment operator and lessor personally — not to their auto or general liability insurers (Supreme Court 2022Da214040, citing Supreme Court 2006Da60793).
Q. Was there a dissenting opinion in the en banc ruling?
Two justices filed a separate concurrence agreeing with the outcome but opposing the new “shared risk” standard. They argued the traditional insurance-relationship test should be preserved, with the same result achieved by analogically applying the consolidated premium rules for subcontracted work under Article 9(1) of the Employment and Industrial Accident Insurance Premiums Collection Act.
Q. What should foreign companies with construction or logistics operations in South Korea do?
Review your workers’ compensation and liability insurance coverage to ensure it reflects the full scope of on-site operations, including equipment lessors who work under your direction. Have contract templates for combined equipment-lease and operator-labor agreements reviewed under the new shared-risk standard.
