The profundity of your lack of comprehension of the role played by the judiciary, including the SCC, in our Parliamentary democracy is astonishing, but not surprising.

How did the judiciary ascend to the position that you decry?  Don't jump to a quick answer; think about it.  Ready?  The elected governments you extol passed the laws that created the position of the judiciary.  That's right; governments elected by the people did it.  If a sufficient number of people don't like the present situation, the government can change those laws.  Admittedly, that's not easy to do but the mechanism exists.  Apparently, there just isn't enough interest in doing so.
