I think that you are totally wrong.
The will of the people in a democracy is sovereign.
Above the Crown (as was amply demonstrated to Charles 1st)
The Conservatives included an 'In or Out' referendum in their manifesto.
The people voted for it.
The referendum was held and Brexit won.
The only mention of 'Advisory' came after the result from disappointed remainers.
Sorry Mike you are totally wrong....if you do some searching,a statute is sovereign,a statute empoyers parliament over the royals and the people.
This goes back to the Act of Proclamation,James1V,1610 when the King tried to issue a Proclamation that no houses be built in sight of his castle.It was put to parliament and decided that an act of Parliament(statute) always superseded a royal Proclamation.
This is the test case to stop Theresa May using the Royal Prerogative to trigger Article 50,she will lose that case in October. IMHO she knows she will lose that action but it will then be put to judicial review,to the Lords,that may take 18 months,by then everyone will have lost interest in Brexit and May can bow out gracefully. Just a shame that common sense doesn't happen now ,we will waste billions in legal fees to move to a situation that is Mays exit route and damage our trade in the meantime.
The referendum was only advisory,this was known before the vote but not mentioned,parliament can choose to ignore the vote,if the repeal of the European Communities Act was put to parliament they would reject the repeal,without that we cannot leave the EU.
Cameron did not investigate the details of leaving because he thought there was no chance we would vote leave,it is only now that the legal difficulties of leaving are apparent.
The latest difficulty for May is Gibraltar....they voted 98% to stay in the EU,we also guaranteed that they would remain UK citizens. The Spanish have said that for Gibraltar to have an open border with Spain they have to be an EU state,all these matters are contradictory. Combine this with the problem of Northern Ireland bordering Ireland and Scotland saying that they voted to stay in the EU and will seek independence if the UK leaves.
There is absolutely no chance that May can trigger Article 50 before 2020,the legal implications are too complex and then a new government will have to reject the past,the referendum will be long forgotten and a new manifesto will make some passing referral to pacify the leavers.
In the meantime it will be a complete mess,satisfying nobody.
