Gift deed through general power of attorney

Three parties A=Father B=Mother C=Son C gives A general power of attorney without stating tenure of validity and is living abroad. POA has been registered. POA has clause that says quote " To sell, gift,exchange, surrender, issue or dispose of my said property and to transfer, release any mortgage or also to enforce any powers of sale or others under any such mortgaged or charges or otherwise to realize or obtain the benefits thereof in such manner as my said attorney shall think fit and proper" A purchases a property (flat/apartment in a housing society) 10 years ago using C's money in the joint names of C and B. This year A writes an application to the secretary and chairman of the society where the flat/apartment was purchased, presenting them with a gift deed which is executed by A as acting attorney of C, claiming that C is gifting his shares to B. Gift deed is registered and stamp duty has been paid and this was verified online using the document number stamped on it And also present the general POA which C granted to A. Society based on documents presented, transferred the shares of C to the name of B making B the sole owner of the Flat/Apartment One month post the transfer, B writes to the society saying that the POA stands revoked and that the transfer is null and void. 1. In this situation, were the office bearers of the society right in transferring the shares? 2.Can the office bearers be held accountable in a criminal or civil suit? Thanks
