The purpose of that Senate is that they should have representative from the federating units sitting there as having equal representation, so that they could safeguard the interests of their own Provincial units. Now, in order to safeguard them that Senate must have some power, but if it is a Senate without a power, then how is that Senate going to solve the problems? You could call it a debating society, you could call it an advisory board, give it any name you like, but it is certainly not there to ensure or assure the Federal structure of this Constitution.
