Bombay rent control act

My son is staying at Mumbai with my wife's parents in a rented flat.Rent receipt is issued in name of my mother in law and my wife.My wife is staying at Ahmedabad and her parents want to shift to Ahmedabad due to age.Can the landlord claim the premises back on ground that none of the members in whose name the receipt is issued are not staying, or as the grandson is in occupation of flat the landlord wouldnot be able to claim it back?
