Section 297 applies to all companies, public as well as private. However, it does not apply to the contracts where both the parties to the contract are public companies. The section would apply where one of the two companies (being parties to the contract) is a private company and the other is a public company, but in such a case, it will have to be complied with by the public company only.
The Directors occupy a fiduciary position in relation to a Company. They must act bona fide and in the interest of the Company. This duty of good faith which fiduciary relationship imposes is identical with those imposed on trustees. In this sense, it can also be concluded that the Directors are trustees.
Thus, if a Director makes contract with the Company and does not disclose his interest therein he will be committing breach of trust.
