In fact I was going to answer Baguettes question about what happens next but I made the mistake of opening the link to "Harrys" foray into reactionary woke politics.
Anyway back to IL 2019 000110
They key thing is the Trial Window which is the period of a few weeks in January 2021 when following what is quaintly called a "tea party" the clerks for the barristers fix the trial date in stone for a 7 day trial, and nothing but settlement can stop it happening. Settlement can happen at any time - hopefully before too much money has been wasted but quite commonly during the trial when it already has been, frequently the day before, and above all USUALLY 95% of High Court Claims settle before trial!
In order for the Trial to happen the parties need to complete "disclosure and inspection". Each sends the other a highly ordered list of all the material: documents, YouTube clips you name it, they intend to rely on in the trial. Subsequently it becomes increasingly difficult to add to Disclosure although in practice new material often crops up. Eventually you need leave to introduce it which gets more tricky the closer you are to trial. Inspection just means the other party has a right to see all the Discovery including the original form of all documents etc to check their veracity.
This can lead to disputes between the parties about the extent of Dislcosure and also applicatiosn for Court Orders for Dislcosure of things the parties want to keep hidden. Very likely in this case from both sides.
Then the parties Exchange Witness Statements. These contain a summary of the Evidence that each Witness will give. As with Discovery introducing new Witnesses becomes more difficult as Trial gets closer; and I suspect there will be disputes especially about the FFF. I suspect only friend B will be put forward to speak for all of them and this will result in another Application to Warby (or whoever, its not necessarily always going to be him).
There is then a Case Mangagement Conference at which any outstanding issues are resolved and the Parties have to disclose both how much they have spent so far and what they expect to spend to the conclusion of the Trial. The Court can impose limits. If you then go over these limits, without seeking permission, you cant recover the excess if you win.
The CMC will also determine special factors like Expert Evidence (cant quite think what in this case: Yoga?) Remote Evidence (possible) etc.
Then the Trial of the Century
In parallel the parties have to explore settlement. This can be informal but is usually a formal process of ADR (alternative dispute resolution) which can be nearly as expensive as a trial with the parties and lawyers posturing in front of each other, over fancy sandwiches and stilted legal anecdotes, about how certain they are they are going to win when everyone knows that at least one party, or at least their lawyers, think the exact opposite.
Thats it from Aunty.
