Rules & countermeasures against Amalgamation of a select plots in a Cooperative Society

I stay in a cooperative society registered as a bungalow plots Society with a garden and Gym. No commercial activities take place in the garden for Society to earn income. I am a member of the managing body of the parent Society. Society is registered in 1962. Due to the remoteness of the location then construction of flats was allowed on the plots somewhere from 1972 onwards. The Society has total 26 plots out of which only 4 plots now have bungalows. Now the old apartments/ownership buildings have started looking for redevelopment on their respective plots. Only a few days ago the parent Society has adopted the 97th edition of Cooperative Bye-laws for the Society. We expect the builders will try to lure 4 apartments (plot lease holders) to come together for redevelopment. Then they will put a proposal to the main Society to sign documents to amalgamate the said 4 plots so the builder can get higher FSI. We do not wish to allow this. Kindly let me know what preventive actions the parent Society's governing body should take before the builder comes with the proposal for amalgamation & NOC from the parent Society.
