Not referring to parliament something based on a non binding and advisory referendum is leaving a bit of a gap on the sovereignty of parliament and quite gives the impression of a little cognitive dissonance.
The spectacular arrogance of all MPs pre referendum is what has left us in this position.
Nobody truly contemplated a win for Leave, hence they voted through the ref and its loopholes with no real scrutiny.
The result is that the people were asked to make a decision on EU membership, and were assured (repeatedly, by both Remain & Leave advocates as well as the PM) that whatever they decided would be enacted.
We decided:
Leave the EU.
Re prerogative- as has been pointed out already, it is used all the time.
Its usage in this particular scenario is what is being judged.
As I said earlier in the thread, whatever the outcome, I am glad to live in a free country whereby voices are heard.
We are allowed, as citizens, to challenge our govt - the judiciary is independent of govt & parliament is bigger than one person when necessary.
I would like the outcome to be that prerogative is enough (as I believe it should be - enacting the choice of the electorate as we were promised).
However, I would hope that if the verdict goes in favour of parliamentary approval rather than prerogative, the Remain contingent remember that the majority of the electorate voted to leave, and don't conspire to subvert Brexit completely.
