Re: Vogon
Close, but a better and fairer version would be that if 'none of the above' wins, the position in question is left vacant for the term, and its powers are not exercised.
If sufficient positions in a body are left vacant, and quorum becomes impossible, then that body is suspended until such time as a quorum is elected, and its powers are not exercised.
I love this idea. Turnout in EU elections has been below 50% since 1999, so with this rule the EU would have been suspended for the past 20 years!
