This isn’t a facetious question, well it’s not an entirely facetious question it may be a little facetious. The reason to ask is as follows …
… I, for instance, live in the Republic of Ireland and I’m not an Irish citizen so I don’t get to vote on constitutional matters referenda and so on. If the republic decided to have a vote on leaving the EU or had a load of votes until they accepted an EU treaty I wouldn’t get to vote in it. Nor should I, I’m a guest in this country and I shouldn’t be determining the long decisions. Short decisions, like local and national government elections I get to have a say.
Surely then, for Scotland, only people who would have the right to be Scottish citizens if they gained independence should be able to vote. This would include a lot of people currently living outside Scotland. It would also exclude a lot of people currently living inside Scotland. If the act of dissolution of the Union would make you an expat in Scotland you shouldn’t get to vote in a constitutional decision regarding Scotland. That makes sense and at the same time it doesn’t.
Would I get to vote in it? I consider myself English but my grandmother was Scottish. So I could, presumably play football for Scotland (I wouldn’t obviously, I’m awful at football [Insert rather obvious joke here]). Would that make me eligible for dual nationality? Would there be any tax benefit to doing that?
