Who decides at any given moment that a sufficiently large chunk of the population wants a referendum?
Ummm... The electorate? If part of a parties manifesto is pushing for a referendum, and that party gains a majority in a parliament designed to prevent majorities, that's a fairly good indication... Democracy in action...
And suppose that ends up with a 60% No vote, can he then decide on 1st November that, goodness me, a large chunk of the population wants referendum no. 3?
If a government held a referendum on the same thing every week they would likely piss off the electorate, and not be voted in again. Hence unlikely to happen. Democracy again you see.
And, of course, it wouldn't be restricted to independence. You would get people clamouring for referenda on capital punishment, immigration, banking control, hunting, corporal punishment in schools, abolishing gay rights, enforced church attendance, you name it. The country would be paralysed by virtue of the fact that we were constantly trotting off to the polls, and every time someone in power didn't like a result they could simply decide to rerun the referendum.
See above answers. But yes, if a majority government is elected on the basis they will run a referendum on one/some/all of the above of course the referendum should run.
You really don't get democracy do you.
"Democracy is a form of government in which all eligible citizens are meant to participate equally – either directly or, through elected representatives, indirectly – in the proposal, development and establishment of the laws by which their society is run."
