Why Outside Eyes Are Needed — The Independence of Outside Directors

A decision made strictly among insiders can only be tested by insider logic. Outside directors exist not because we suspect management, nor because we trust it, but because of a structural problem: a party to a decision cannot fully audit its own conflicts of interest. Using Article 327-2 of the Companies Act and the independence criteria as a guide, this piece reads why outside eyes are built into the system, brought down to the materials-review floor.

01A Party Cannot Verify Itself

An outside director supervises the directors' execution of their duties from a position independent of management. Why are insiders alone not enough? The reason lies not in competence or integrity, but in position. Those within the same chain of command find it hard to dissent from a superior's judgment and hard to appraise, coolly, whether a conflict of interest is present. However conscientious the individual, the structure pushes them that way.

This is the same shape as materials review. If the materials the sales side produces are checked by the logic of that same sales side, the lean toward "expressions that sell" is hard to halt from within. A party alone cannot fully audit its own conflicts of interest. That is why both review and the board need eyes that stand outside the party. This is not a doctrine of human goodness or human badness; it is a design for securing the independence of verification.

02"Appoint One If You Can" Does Not Stabilize the Check — Article 327-2 of the Companies Act

Leave the outside eye to discretion, and it gets omitted precisely when it is most needed. So Article 327-2 of the Companies Act made it mandatory for listed companies and the like to appoint an outside director. Who counts as "outside" is defined in Article 2, item 15, which excludes relationships deemed to make a person one with the company — such as past tenure within a set period, or kinship with management. Beyond that, the Corporate Governance Code calls for the appointment of independent outside directors and, for the Prime Market, presents one-third or more as the expected level.

Mandating and defining go together. Fill the seats by headcount alone and the check still will not work if, outside the definition, the appointees are in substance one with management. Formal requirements are a device for securing, by outward form, the hard-to-see quality of independence.

03Effectiveness Is the Product of Two Conditions

Appointing an outside director does not guarantee that supervision works. Effectiveness is the product of two conditions. One is access to information. If what the executive side passes up is thin, the outside eye has no material on which to judge. The other is independence. If a director depends on management economically or personally, they cannot speak even when they know.

Lose either one and supervision becomes nominal. The same holds in materials review. If information about a deviation stalls on the floor and never reaches review, no judgment can be made; and if review's evaluation and personnel are subordinate to sales, its findings go blunt. Cutting off information and subordinating review to sales each hollow out independent review from within. The "in-name-only" outside director and the "merely formal" review arise from the same two missing pieces.

04Why Bind by Formal Requirements — Severing Deference at the Structural Level

The independence criteria carefully exclude major business partners, kinship, and prior tenure within a set period in order not to rely on good intentions in operation. A relationship in which deference to management slips in easily will, however honest the individual, bend judgment unconsciously. So the relationship itself is excluded in advance. Formal requirements may look constricting, but they are placed there as a fence that physically secures the check.

The independence of materials review is protected by the same idea. Separating review from sales organizationally and dividing the authority over evaluation exists to make the check hold without depending on the reviewer's character. Building a state in which "it stops no matter who does it" is the substance of independence.

05Reading It Within the Chain of Supervision

The independence of an outside director is not complete on its own. It stands on the division of roles by which the board supervises execution (Vol. 1), and only when combined with the three committees that carve out nomination, remuneration, and audit (Vol. 5) and the three lines of defense across the front line, management functions, and internal audit (Vol. 8) does the check come to form layers. The meaning of materials review keeping its independence as the second line, too, grows easier to see when placed within these layers. One outside eye is not enough; only stacked do they take effect.
