The rules of a registered society shall be amended for the purpose of bringing them into conformity with the provisions of this Act, and amendments made for that purpose shall be sent to the registrar within one year from the day appointed for the coming into operation of section twenty-two of the National Insurance Act, 1946.

If the registrar is satisfied, and certifies, that amendments sent to him within the period required by virtue of the preceding subsection, or within such further time as the registrar may in special circumstances allow, are for the purpose of bringing the rules of a registered society into conformity with the provisions of this Act or for the purpose of enabling the society to exercise any power conferred by this Act, and have been approved by the committee, he may register the amendments notwithstanding that the provisions of the rules of the society as to the alteration of rules or the making of new rules have not been complied with, or (in the case of a friendly society formed and established before the fifteenth day of August, eighteen hundred and fifty) that the rules of the society do not make provision for the alteration thereof, and an amendment registered under this section, shall, unless it is for some other reason invalid, be valid notwithstanding as aforesaid.
