I just know when we went union at the airline I was at, we had to call a number and vote either yes or no, yes needed a majority to bring the union in.

If someone did not call, they were not counted either way.

Clearly things have changed since then.

The last Independence for Scotland referendum

Giantaxe

There's never been a referendum on independence for Scotland. If you mean the proposed referendum of Nov 2010, that would have used a simple majority of votes cast. Or perhaps you mean the devolution referendum of '79, which used a threshold of 40% of the electorate voting in favour? Or the '97 referendum on devolution? Not sure what the rules for that were but again 50% of the electorate didn't vote in favour of either question.

I have a vague recollection that one or more of the Quebec independence votes might have had a plurality of the electorate requirement.
