Our is a housing society - we have 2 wing - A & B , both wing terrace is not connected hence can not use the lift of other wing in case of emergency.There is one lift per wing. The building is a 7 storey building.Recently society passed a rule that a member cannot carry any materials require for the repair/ renovating his flat & also cannot carry his belongings like furniture, and household materials in case of shifting or in case of buying new one,we are forced to use staircase in case of buying of new furniture or buying of any materials.My question is this rules is justified? in the books of law? or we can challenge this rule as per the law
