In the event that any clause, sentence, paragraph, section, idea, or other part, portion, or provision of this subpart is held unconstitutional, such holding shall not affect the remainder of this subpart; it being hereby declared to be the intention of the Legislature that should any part or portion whatsoever of this subpart be held unconstitutional the remainder shall be in full force and effect, and that the Legislature would have passed this subpart without such invalid portion. Without limiting the generality of the foregoing it is hereby expressly declared and provided that if every provision of this subpart excepting the enacting clause and the provisions requiring contributions from the salaries of firemen and policemen and matching contributions from funds of the city to be paid into the fund created by this subpart should be held invalid or inoperative, then in that event the enacting clause and the provisions requiring contributions from the salaries of firemen and policemen and requiring matching contributions from the city shall remain in force and effect so as to establish a supplemental pension fund out of which there can hereafter be made provision for paying to the firemen and policemen out of the supplemental fund such additional benefits as it may hereafter be established can be paid from the supplemental fund on a sound actuarial basis.
