The entire system derives its legitimacy from the majority vote
No it bloody disna!
Bitofacow has it right:
"In a direct democracy an MP would have to act as directed by their constituents, perhaps via referenda. In a representative democracy the constituents hand over responsibility to the MP who votes in accordance with their own, the MPs, beliefs.
Therefore an MP is not required to vote in a way the majority of constituents would agree with, unless the MP wants to.
MPs are accountable to constituents via the ballot box at elections.
In effect we hand over responsibility for decision making to our MPs. Yet another reason the referendum was a farce."
And, it seems, the judges agreed.
