"The court has merely said that parliament must be 'consulted', it does NOT say any vote in parliament can stop leaving."
No it has not. It has said the exact opposite. You can read the judgement in full at https://www.supremecourt.uk/cases/uksc-2016-0196.html but if you wish I can save you the effort. The relevant paragraph is number 24 on p 39 (of 97; after a long analysis of the constituational history, the relevant legislation and the legal arguments and followed by an analysis of the issues raised by the devolved governments and the minority dissenting opinions).
"Thus, the referendum of 2016 did not change the law in a way which would
allow ministers to withdraw the United Kingdom from the European Union without
legislation. But that in no way means that it is devoid of effect. It means that, unless
and until acted on by Parliament, its force is political rather than legal. It has already
shown itself to be of great political significance."
Consultation is not enough. There must be legislation. And it must be before the triggering of Article 50 as it is common ground of both parties that once invoked Article 50 cannot be stopped (para 60 on p9 if you want to check).
It beggars belief that the Leavers are so fixed in ignoring anything whatsoever which contradicts their view of the world. It does not augur well for the future when one considers that this is the quality of knowledge and thinking which has driven their votes.
