In a democracy where government is supposedly " of the people, by the people, for the people", the clear objections of the people are expected to heeded and acted upon in order to answer the objections.
In a democracy, if the people demand differently than that which their representatives have forced upon them, then the will of the people is expected to be heeded and not overruled.
However, when the objections of the people are overruled, then the people owe it to themselves to challenge the political process which is of them, by them and for them. Therefore, once the people are duly overruled by their elected representatives, then the people must cast said representatives aside for failing to rule for the people. Hence, a new government should be established.
