We go through a mid-term review. We had one halfway through this current mandate. The members assessed the progress and the work produced by the various cabinet ministers. One minister fell, was voted out. It's a system of checks and balances on how the government is doing. After that, there are really no checks. They pretty much have another three-year pass, because as long as they appease a couple of members from the other side, they maintain a majority. That's how the system works. It's not always healthy.
In a party system, you go in with a clear mandate and you produce the results; if you don't, good luck in the next election.
