There was nothing wrong with the referendum.
There was a great deal wrong with it.
You wrote "The piblic[sic] were[sic] asked a very simple question and there were only 2 possible answers"; "have you stopped beating your wife yet?" is another very simple question with only two possible answers. Does that make it right to ask either?
What you yet again omit to address here is why that particular question was asked of the public in a referendum when almost any other legislative one would instead be debated and voted on in Parliament.
Asking the p
ublic to vote on something because just one UK political party was scared of the risk of defections to UKIP from within it was undoubtedly wrong, both morally and legally, for this was no excuse whatsoever to raise the subject of UK's continued EU membership, especially when that very issue had already been subjected to referendum once before (albeit 41 years ago).
What was also wrong - though not specifically with the referendum itself or in principle - was the manner in which it was conducted by both sides. How dare the government not only take sides in it but charge citizens an almost 8-figure sum for marketing in favour of Remain? That in itself makes a mockery of its calling of a referendum. The lies, damned lies and speculations paraded as statistics sullied the entire procedure, particularly as most voters who could already not be expected to know enough about the pros and cons would inevitably be swayed by them.
Another thing that was wrong - or at the very least most unfortunate but possibly nevertheless to some degree predictable - was the divisiveness to which it gave rise, given the difference in support not only between the UK's four nations but also between its city dwellers and its non-city dwellers (and possibly to some degree also between different age groups).
That it helped to foster some increase in racist hate crime may not necessarily have been "wrong" with it but it was certain far worse than a mere misfortune.
Lastly, it was wrong of the government of the day to try as it did to conceal from the electorate that the referendum was not legally binding; had all those who voted in it been notified of this at the outset of what was to become the shoddiest campaign in living memory, I suspect that most would have abstained.
These silly court cases will only earn huge sums of money for the legal proffesion, as they always do.
The fact that you regard them as silly expresses your opinion of them in advance of their being held but does not make them so; you regard them as such solely because you disapprove of anything that might risk undermining Brexit or interfering with its progress.
All legal cases earn sums of money for the legal profession as well as for the judicial profession; how "huge" those sums will be in the cases concerned will depend upon their complexities as well as the level of fees charged by the lawyers, barristers, judges, court staff
et al and whether any of them might go to appeal, but that's no different to any other Court case.
If the government of the day were to consider the possibility of restoring the death penalty in UK (
horresco referens!), would you expect it to subject the issue to referendum?
Best,
