There is nothing wrong with a coalition forming government.
BUT, to be legitament, they MUST get their mandate from the people to govern, ie tell the people your a coalition and let the people vote for you.
Well the way it is set up is total bull. A Minority government can be toppled right after an election if the other parties agree on doing a coupe and the Governor General can hand over the keys to them. Doesn't matter what the people think.
Technically its legal, but it is so far from democratic I don't even know where to start.
That is one part of our parliament that should be done away with.
