alt Hacker News> What's shocking of course is that the Brexit vote didn't end up the same way ("ok the vote passed but it can't be done anyway").
There was an attempt.
A campaigner managed to get the courts to issue a verdict that the referendum was not binding, and Parliament must then have a vote on whether or not to implement the result. Remain voters rejoiced and lauded her as a hero. Brexit voters demonised her as an enemy of democracy.
Parliament then duly voted to implement the result.
(Edit - looking back this may have been counterproductive. The argument that the referendum was not legally binding could have continued for some time, maybe even long enough to try to change something. But forcing a parliamentary vote to affirm the result put all that to bed)
Which was, procedurally, the correct course of action: the referendum was non-binding, because the UK's constitution only allows for non-binding referendums. Parliament is sovereign, whether you and I like it or not (and I'm generally ambivalent about it).
Given one of the major themes of the leave campaign was "restoring parliamentary sovereignty", it's darkly ironic that leave also campaigned against parliament actually using that sovereignty, and indeed came closer than anyone else (including the EU) to restricting parliamentary sovereignty.
