Someone said :
Article 50 is reversible, a confirmed by John Olav Kerr who contributed to drafting it.
The EU Commission stated that they considered the triggering of Article 50 as "not unilaterally" irreversible, but that is just a political statement
, not a legal advice. It mens that the UK would have to grovel a bit to reverse the situation, and would lose some past advantages, so that no other nation gets the idea of using Article 50 to blackmail the others.
So the revocation will require some negotiations, but it is absolutely possible. Article 50 is a declaration of an intention to leave, not a notification of withdrawal
. As long as no agreement making the Treaty inapplicable is taken, it can be revoked. They will not need to reapply unless they change their minds AFTER the official leaving date (date which could be extended by common agreement).
It's impossible that they don't leave having voted for it by popular vote and in parliament , technically of course everything is possible but they are exiting even if they change their minds. The reality is leaving isn't really leaving because they've already begged for a transition phase which means 2019 becomes 2021 and in reality this will probably become 2025 do you think the British have done any preparation at all? This phase might even be 9 years !!!!!!!!!! Breaking up is so hard to do.
This implementation might become the permanent condition ? Who knows they don't ... it might be the best they can negotiate .
