In What Circumstances Do a Director's Duty to Monitor and Duty to Establish an Internal Control System Give Rise to Liability for Damages?

The Starting Point of the Case and the Core Legal Question

Supreme Court Decision 2017Da222368 rendered on November 11, 2021 (litigation concerning a company) squarely addresses the following question: in a company that received a surcharge for long-running, large-scale price fixing, how far does the representative director's duty to monitor extend?

The Supreme Court's core conclusions may be summarised as follows. On the basis of Article 399 (1), Article 389 (3) and Article 209 (1) of the Commercial Act, the Supreme Court set out the representative director's general duty to monitor. Even in a large company where a division of labour is unavoidable, the duty to monitor is not discharged merely by the internal allocation of duties; an internal control system must be established. That system is a mechanism that must not be confined to preventing accounting fraud but must include management of legal compliance and arrangements for reporting and corrective action. The price fixing in this case continued from November 2004 to November 2010 across several product lines through meetings of executives and meetings of team leaders, and surcharges totalling KRW 32,043,000,000 were imposed. Even where no direct instruction is found, liability for breach of the duty to monitor arises if the director neglected the matter without making any effort to establish such a system. The operative part reads: "The judgment below is reversed, and the case is remanded to the Seoul High Court." The judgment's mode of reasoning is the setting out of requirements (following existing precedent).

This analysis follows the structure of the issues and the criteria for judgment appearing in the published judgment, and examines why the lower court and the Supreme Court read the same record differently.

The Structure of the Issues Set by the Holdings and Referenced Provisions

The framework of the holdings as summarised in the judgment is as follows. [1] Whether a representative director who, despite grounds to suspect that another director's execution of business is unlawful, intentionally or negligently breaches the duty to monitor and leaves the matter unaddressed is liable for the damage the company suffers as a result (affirmative). [2] Whether, in a large company, the mere fact that it is unavoidable for the representative director and the directors in charge of particular business to handle their respective areas of expertise exclusively under an internal allocation of duties exempts them from the duty to monitor the other directors' execution of business (negative, in principle), and the form of the internal control system that must be established in such a case / Whether a representative director who, although a high legal risk is foreseeable in light of the company's objects, size, nature of business, statutory regulation and the like, makes no effort whatsoever to establish a related internal control system and ensure that it operates properly, or deliberately disregards the performance of the duty to monitor and supervise through such a system, and thereby fails to prevent unlawful execution of business by other directors and others, has neglected the duty, as representative director, to monitor the company's business as a whole (affirmative).

The referenced provisions to be read together in this case are [1] Article 209 (1), Article 389 (3) and Article 399 (1) of the Commercial Act, and [2] Article 209 (1), Article 389 (3) and Article 399 (1) of the Commercial Act. The first step is to separate, among the constituent elements or the requirements for the arising of a right laid down in the wording of the provisions, how far the domain of statutory interpretation extends and where the domain of fact-finding in the individual case begins.

In relation to prior precedent, this judgment stands in the position of following existing precedent. Read alongside the referenced precedent ([2] Supreme Court Decision 2006Da68636 rendered on September 11, 2008 (Gong2008Ha, 1345)), it shows how the Court maintained the outer bounds of the existing legal principle while rearranging the factual elements of the specific case.

Analysis of the Supreme Court's Summary of Judgment and Key Holding Statements

The core of the summary of judgment set out by the Supreme Court is as follows. [1] Where a director, intentionally or negligently, commits an act in violation of statutes or the articles of incorporation or neglects his or her duties, the director is jointly and severally liable to the company for damages (Article 399 (1) of the Commercial Act). Because a director of a stock company has a duty to monitor not only his or her own assigned business but also the execution of business by other directors in charge of particular business, the director bears a duty not only to comply with statutes personally but also to monitor and supervise the other directors in charge of particular business so that they, too, perform their business in compliance with statutes. In particular, since the representative director has the authority to perform all judicial and extrajudicial acts concerning the company's business (Article 389 (3) and Article 209 (1) of the Commercial Act), the representative director not only bears a duty to monitor the performance of duties by all employees but also, as a member of the board of directors, has the authority and responsibility to monitor the overall execution of business by the directors in charge of particular business, including other representative directors. Accordingly, where, despite grounds to suspect that the execution of business by another representative director or a director in charge of particular business is unlawful, the representative director intentionally or negligently breaches the duty to monitor and leaves the matter unaddressed, he or she is liable under Article 399 (1) of the Commercial Act for the damage the company suffers as a result. [2] The specific content of a director's duty to monitor may differ considerably depending on the company's size or organisation, type of business, statutory regulation, business conditions and financial condition. Even where, in a highly divided and specialised large company, it is unavoidable for the representative director and the directors in charge of particular business to handle their respective areas of expertise exclusively under an internal allocation of duties, that circumstance alone cannot exempt them from the duty to monitor the other directors' execution of business. In such a case, if a director makes no effort whatsoever to establish a reasonable information and reporting system and internal control system (hereinafter "internal control system") and ensure that it operates properly, or, even where such a system has been established, deliberately disregards the performance of the duty to monitor and supervise the company's business as a whole and consequently fails to become aware of risks or problems requiring the directors' attention, such as another director's unlawful or improper execution of business, the director is liable for damages for breach of the duty to monitor. Such an internal control system is not confined to an accounting management system for preventing accounting fraud; it must be implemented in a form that systematically identifies all the laws and regulations the company must comply with in operating its business, manages compliance with them, and, where a violation is discovered, enables it to be immediately reported or notified so that corrective measures can be taken. In particular, where the representative director, who is in a position to oversee the company's business as a whole and to monitor and supervise the execution of business by other directors, makes no effort whatsoever to establish a related internal control system and ensure that it operates properly, or deliberately disregards the performance of the duty to monitor and supervise through such a system, even though a high legal risk is foreseeable in light of the company's objects, size, nature of business, statutory regulation and the like, and consequently fails to prevent unlawful execution of business by other directors and others, this may be regarded as neglect of the duty, as representative director, to monitor the company's business as a whole.

In particular, the passage in the judgment that directly supports the conclusion is the following: "[1] Where a director, intentionally or negligently, commits an act in violation of statutes or the articles of incorporation or neglects his or her duties, the director is jointly and severally liable to the company for damages (Article 399 (1) of the Commercial Act). Because a director of a stock company has a duty to monitor not only his or her own assigned business but also the execution of business by other directors in charge of particular business, the director bears a duty not only to comply with statutes personally but also to monitor and supervise the other directors in charge of particular business so that they, too, perform their business in compliance with statutes."

This statement does not remain an abstract declaration; it operates as the reference point for identifying which legal premise the court below omitted, or which factual elements it overestimated or underestimated.

Competing Readings of the Same Facts

In this case, the court below held that there was no specific evidence to find that the defendant, as representative director, had left the officers' and employees' unlawful acts in connection with the price fixing unaddressed or had neglected the duty to monitor, and that the evidence was also insufficient to find a breach of the internal control duty, such as the company's failure to establish a proper internal control system. By contrast, the Supreme Court's legal principle proceeds on the premise that the specific content of the duty to monitor may vary depending on the company's size or organisation, type of business, statutory regulation, business conditions and financial condition, and assesses the matter by reference to whether there were grounds to suspect that another director's execution of business was unlawful, whether the duty to monitor was breached, and the efforts made to establish and operate an internal control system.

Accordingly, when analysing similar cases, one should not merely quote the concluding statement but should test, as a counter-hypothesis, how the conclusion would change if any one of the factors listed in the table above were absent.

Remaining Questions and Conditions for Re-examination

The follow-up question that remains after reading this judgment is as follows: in an oligopolistic market with strong incentives for collusion, what reporting structure must a representative director put in place to be regarded as having fulfilled the duty to monitor?

It is also clear what subsequent materials or precedents, once accumulated, would require this analytical framework to be re-examined. If minutes of meetings or materials on reporting structures showing efforts to establish and operate internal controls are additionally confirmed, the assessment will be revisited.
