I think even more experts will tell you that this could only be done under a multilateral constitutional change process. The Constitution already sets out, in section 42, that you cannot touch the powers of the Senate without using the 7/50 formula. If you eliminate all powers, a fortiori, this procedure applies. There are even some experts who claim that in such a case, one would have to evoke section 41, because you would be changing the process for constitutional amendment, which gives the Senate certain powers, a suspensive veto as far as certain constitutional amendments are concerned. Therefore, in all honesty, it seems absolutely unthinkable to me that the Senate could be unilaterally abolished.
