One flat one vote is the law. Any owner owns multiple units then more voting right. Cant help it.

Register your association as cooperative society 

adopt bye laws wherein each unit has only one vote irrespective of size of unit 

It’s per member 1 vote

The voting rights of members of an association cannot be based on the area of the dwelling unit or commercial space. For each member there can be only one vote.

Voting right should be on the basis of unit only and not on the basis of size of unit. 1 Unit = 1 Vote.

Position taken by group 2 correct, one unit one vote that is the law. Size of unit does not matter.

One flat, one vote, rules SC:

Can the bye-laws of a co-operative housing society curtail the voting rights of different members of a holding separate flats in the building? No, says the supreme court: it's one flat, one vote.

On November 2, 2007, Justice S B Sinha and Justice Harjit Singh Bedi held that Section 27 of the Maharashtra Co-operative Societies Act 1960 Act clearly provides for one vote per member.

The court observed that even though the objective behind "one family, one vote" may be laudable, it is necessary to see whether such a concept is provided for under the act. The court held that when the legislative act provided for it, no bye-law could create another concept to defeat the legislative intent.

The appeal filed by the society agaisnt the dismissal of appeal by Bombay high court before supreme court was dismissed.

Therefore the group 2 which states that one unit per member for the voting rights is correct.

It does state voting right 

section 14 deals with contents of declaration

[Act No.29 of 1987] 11
(f) value of the property and of each apartment, and the percentage of undivided interest in the common areas and the facilities appurtaining to each apartment and its owner for all purposes, including voting;

No, the stated clause does not give any voting right but it clarify that with each unit I.e.flat voting right is attached. 

The clause mentioned in your subsequent post of this thread do not give any extra voting power to the owner having more extent of UDS than the  owner having lesser extent.

The provisions of law stated is declaratory in nature about the issues pertaining to the issues pertaining to common areas.

The Supreme court rules of one unit one vote prevails without any doubt.

Yes it states 

If one unit is 20000sqft than only one vote.

Dear client,  

Yes, Section 14(f) of the Telangana Apartments Act, 1987 provides for the percentage of undivided interest in the common areas and facilities appurtenant to each apartment and its owner for all purposes, including voting. However, it does not specify the method of determining voting rights.

In the absence of any specific provisions in the bylaws of the association or the Telangana Apartments Act, 1987, it is generally advisable to follow the principle of 'one unit, one vote'. This principle ensures that each unit owner has an equal say in the affairs of the association, regardless of the size or number of units owned. It is a fair and democratic method of voting and is commonly followed in most housing societies and apartment associations in India.

However, you may seek the guidance of a local property lawyer to check if there are any specific provisions under the Act or local laws that may apply to your case. The lawyer can help you draft the bylaws of the association and ensure that they are in compliance with the applicable laws.

Dear Sir

THE TELANGANA APARTMENTS (PROMOTION OF
CONSTRUCTION AND OWNERSHIP) ACT, 1987.
