Election Quick Count Are They Valid?

[Philippus Flavius Homovallumus]

If a government loses an election, but we don't know they've lost it until a few days after the election, they may take actions without a clear mandate. What if there is a huge International crisis the day after the election... who should be in charge?

I would also rather that my new government start working as soon as possible to achieve what they have promised.

That's merely a failure of your constitution. In any case, a certain population should presupose a certain number of Returning Officers, counting offices etc., so a "quick count" is merely indictive of a lack of infastructure.

Worse, you can end up with the wrong people in power, at which point it might be difficult to get them out of power.
