Sec. 2. Before any such Board shall adopt as part of its plan for retirement benefits the presumption, together with qualifications, set forth in Section 1 hereof, it shall take the following preliminary step(s):
(a) Obtain an actuarial study showing how the proposed change in benefit eligibility standards will affect the financial condition of the fund.
(b) In the event that such actuarial study shows that inclusion of the proposed change in benefit eligibility standards will not make the fund financially unsound, then said Board shall, within thirty days after receipt of such actuarial study, hold an election in which the active participants contributing to the fund shall vote on the question of whether such benefit eligibility standard should be instituted, said Board being bound by the results of such election.
