"… of maintaining and increasing the Provident Fund by the contributions of such officers [sc of the Bank], and of providing pensions and allowances for officers of the said Bank, and for other cognate purposes."
"The rules for the conduct and management of the business and affairs of the Association shall consist of the rules set out in the Schedule to this Act, with such additions as may be made from time to time, but subject to any alterations or amendments that may be made therein by the Association in the manner prescribed in and by such rules. Any copy of the rules of the Association sealed with its seal shall be prima facie evidence that they were duly made and are the rules for the time being in force."
"(a) To provide a guarantee to the Bank for the fidelity of officers now or at any future time in its service, and to maintain a Guarantee Fund for that purpose. (b) To maintain a Provident Fund to be applied for the benefit of full members of the Association."
"The members of the Association shall consist of the persons who were formerly on the staff of the Bank but are now pensioners, and such other persons as are now or may at any time hereafter be placed on the staff of the Bank, and they shall be divided into three classes:- (1) Full members, ie, members who contribute to both the Provident Fund and Guarantee Fund, or who are full members as provided in Rule 18 [relating to an alternative guarantee fund]. (2) Members who contribute to the Guarantee Fund only. (3) Pensioners."
"The rules for the conduct and management of the business and affairs of the Association shall consist of the rules in force at the passing of this Act, with such additions, alterations, and amendments as may from time to time be made in accordance with those rules."
"In 1990 the rules were redrawn so as to create two divisions. Division 1 was for existing pensioners and those existing members who wished to remain part of the traditional pension scheme, while Division 2 provided for a new cash accumulation benefit structure. Within this new Division, members' benefits were defined by reference to the members' individual contributions and those made by the employer, together with earnings on those contributions. Members could elect to transfer to the new division of the scheme. Those members who transferred across to the cash accumulation division took with them a 'transfer value' that reflected the actuarial value of their accrued pension based benefits. Over 95% of members elected to transfer to Division 2. As membership of Division 2 was voluntary, a number of members chose to exit the existing scheme following transfer. The pension based scheme (Division 1) was closed to new members. After 1990 all new members therefore had to join Division 2 (cash accumulation benefit structure)."
"The object of the Association is to maintain a Provident Fund for the benefit of Members and Pensioners of the Association and their dependants." (2) (Rule C 1.5.1 - alteration of rules): "
"the Board shall take whatever action for ensuring the equilibrium of the Fund as in its opinion is rendered necessary by the Actuary's report and/or recommendations"
"Following the introduction of the new cash accumulation division in 1990, the Board adopted an earnings policy that saw earnings on surplus assets included in the earnings distributed to members by way of the declaration of an annual earnings rate. If the earnings rate declared by the Board had not incorporated the earnings on the surplus assets, those additional earnings would have been retained in the Fund, thereby increasing the size of the surplus. The Board saw its earnings policy as being equitable in that it enabled members to benefit from the existence of the surplus in the Fund at the same time as the Bank was benefiting from its presence by taking a contribution holiday (that is its obligation to fund its share of the accruing benefits were being met from the surplus funds in the scheme)."
"It is trite law that a power can be exercised only for the purpose for which it is conferred, and not for any extraneous or ulterior purpose. The rule-amending power is given for the purpose of promoting the purposes of the scheme, not altering them. Before I consider this question, I should make some general observations on the approach which I conceive ought to be adopted by the court to the construction of the trust deed and rules of a pension scheme. First, there are no special rules of construction applicable to a pension scheme; nevertheless, its provisions should wherever possible be construed to give reasonable and practical effect to the scheme, bearing in mind that it has to be operated against a constantly changing commercial background. It is important to avoid unduly fettering the power to amend the provisions of the scheme, thereby preventing the parties from making those changes which may be required by the exigencies of commercial life. This is particularly the case where the scheme is intended to be for the benefit not of the employees of a single company, but of a group of companies. The composition of the group may constantly change as companies are disposed of and new companies are acquired; and such changes need to be reflected by modifications to the scheme. Secondly, in the case of an institution of long duration and gradually changing membership like a club or pension scheme, each alteration in the rules must be tested by reference to the situation at the time of the proposed alteration, and not by reference to the original rules at its inception. By changes made gradually over a long period, alterations may be made which would not be acceptable if introduced all at once. Even the main purpose may be changed by degrees."
