How can I deal with disputes related to the redevelopment of society?

A building is in a prime area with 13 flats and 2 garages.6 flats had taken a token of 11 lc each agonist outright sale .that builder has also purchased a flat in the same building. This was 6 years back .the builder has been behind the bars ever since after the PMC bank scam. the secretary and chairman are trying to give it to another builder for redevelopment .we are a flat who has not taken any taken. and feel that redevelopment is risky .what is the option as put of 13 flats most of them agree for redevelopment and that forms a majority  What do we do as the secretary has hinted that when majority is for it ,we don't need to wait for others approval. kindly help as to what should be done as in 7 days there is another meeting and they wud ask us our consent. Also can the society give it to another builder as all had put up thr point and they said that the new  builder will deal with all affairs ...plz confirm as to what should be done .thanks in advance for your guidance
