Decoding Section 166: Fiduciary Duties and Liabilities of Directors#
Section 166 of the Companies Act, 2013, was a landmark inclusion. For the first time in Indian corporate history, the fiduciary duties of a director were explicitly codified into law, rather than being left entirely to common law interpretations.
As corporate governance scrutiny intensifies going into 2026, understanding the strict boundaries of Section 166 is paramount for any individual sitting on a corporate board.
The Six Pillars of Section 166#
Section 166 lays down six specific duties that every director (executive, non-executive, or independent) must strictly adhere to:
- Act in Accordance with Articles: A director must act in accordance with the company's Articles of Association (AoA).
- Act in Good Faith: A director must act in good faith to promote the objects of the company for the benefit of its members as a whole, and in the best interests of the company, its employees, the shareholders, the community, and for the protection of the environment.
- Exercise Due Care and Diligence: A director shall exercise their duties with due and reasonable care, skill, and diligence, and shall exercise independent judgment.
- Avoid Conflicts of Interest: A director shall not involve themselves in a situation in which they may have a direct or indirect interest that conflicts, or possibly may conflict, with the interest of the company.
- No Undue Gain: A director shall not achieve or attempt to achieve any undue gain or advantage either to themselves or to their relatives, partners, or associates.
- No Assignment of Office: A director shall not assign their office to any other person; any such assignment is void.
Liabilities for Breach#
The consequences for breaching Section 166 are severe:
- Fines: A contravention of this section can attract a fine ranging from ₹1 Lakh to ₹5 Lakhs.
- Restitution: Under sub-section (5), if a director is found guilty of making any undue gain, they are liable to pay an amount equal to that gain back to the company.
- Class Action Suits: Shareholders can use a breach of Section 166 as grounds to initiate class-action lawsuits (under Section 245) or oppression and mismanagement claims (under Section 241) against the directors.
The Defense: "Business Judgment Rule"#
While the law is strict, courts generally recognize the "Business Judgment Rule." If a director can prove they made a business decision in good faith, without any conflict of interest, and after exercising reasonable diligence, they will generally not be held liable if the decision ultimately results in a loss for the company. The law punishes negligence and fraud, not honest business mistakes.
Directors must ensure that board minutes meticulously record their deliberations, queries, and the rationale behind their decisions to build a defense against any future claims of negligence under Section 166.
