Worked example

### Example 1

Example 1: A contract on behalf of ABC Ltd is signed by an Assistant Manager who has NOT been authorized by the Board. Is it binding?

Answer: No. Section 21 requires signature by a KMP OR a Board-authorized officer/employee. Without authorization, the contract is not validly authenticated.

### Example 2

Example 2: Mr. X is appointed as MD but is not a director. Is the appointment valid?

Answer: No. The definition of Managing Director requires the person to be a director first. A non-director cannot be appointed as MD.

### Example 3

Example 3: A lawyer regularly advises the Board on legal matters. Is he an 'officer'?

Answer: No. Persons acting in a professional capacity (lawyer, CA, etc.) are EXCLUDED from the 'officer' definition even if the Board habitually acts on their advice.

⚠️ Common exam mistakes

  • Including auditors/lawyers as 'officers' — professional advisors are EXCLUDED.
  • Forgetting that 'officers one level below directors' become KMP ONLY when the Board specifically designates them.
  • Thinking any director can be MD without entrustment of substantial powers — entrustment is essential.
  • Confusing CEO/CFO/CS as automatically being directors — they are KMPs but NOT necessarily directors.
  • Missing the IFSC widening of 'officer' definition in the authentication rule.
