Lewis JA in dissent observed that it would not be sensible or reasonable to require that at least 13 trustees should meet and authorize the hiring of office equipment, as this is the function of the principal officer. She noted that even investment contracts, the prime business of the Fund, may be delegated to a subcommittee or financial institution under Rule 5.2, suggesting the rules envisage delegation. She commented that there is "undoubtedly a gap in the rules" as they do not prescribe how contracts are to be executed when they do not fall within Rules 4.13 and 5, but this cannot mean any contract not complying with Rule 4.13 is invalid. The majority judgment observed that the Fund is free to amend its rules if it finds the procedure cumbersome, but courts have no power to make a new contract for members of a fund. Ponnan JA commented on the distinction between acts that are ultra vires (beyond powers, null and void) and acts within powers but done in a manner contrary to the constitution (voidable, subject to ratification or estoppel), noting that even on the latter approach the appeal would fail due to the Bank's knowledge of non-compliance.
