Section 22 and section 23 sub-sections 1 to 3 have been made applicable to co-operative housing societies by virtue of s.154B(1)
Section 22 - Person who may become member

-----------------
(2 ) Where a person is refused admission as a member of a society, the decision (with the reasons therefore) shall be communicated to that person within fifteen days of the date of the decision, or within three months 5 [from the date of receipt of the application for admission, whichever is earlier. If the society does not communicate any decision to the applicant within three months from the date of receipt of such application the applicant shall be deemed to have been [admitted] as a member of the society.] 7 [If any question arises whether a person has become a deemed member or otherwise, the same shall be decided by the Registrar after giving a reasonable opportunity of being heard to all the concerned parties.]
Section 23 - Open membership
(1) No society shall, without sufficient cause, refuse admission to membership to any person duly qualified therefor under the provisions of this Act and its by-laws.
(2) Any person aggrieved by the decision of a society, refusing him admission to its membership, may appeal to the Registrar 5[within a period of sixty days from the date of the decision of the society]. 3[Every such appeal, as far, as possible, be disposed of by the Registrar within a period of three months from the date of its receipt:
Provided that, where such appeal is not so disposed of within the said period of three months, the Registrar shall record the reasons for the delay.]
(3) The decision of the Registrar in appeal, shall be final and the Registrar shall communicate his decision to the parties within fifteen days from the date thereof.
Thus s.154B-1 clause (b) defines who is a Joint Member. It only says that the joint member has share right title and interest in the flat jointly. It nowhere says that the order of names has to be the same as in the instrument of transfer. Thus the only requirement is that the joint member should have a share right etc in the flat jointly with another.
u/s 154B-4(1) the society can admit ANY person as the joint member. It does not state that only the person whose name stands second in the instrument of transfer [in your case the gift deed] can be admitted as a joint member
the voting rights of joint members are also provided in s. 154B-11 (4)
thus if the society has communicated its reasons against transfer of membership to the joint names in the order desired by you, then you will have to appeal to the registrar u/s 23(2)
and if there is no communication by the society about its refusal to admit the joint members as stated in the application then they would be deemed to become the members of the society by virtue of s.22(2) after the expiry of the statutory period stated therein
