It's been said a number of times on this thread that it would be extremely difficult, virtually impossible for IB to run the UK case when they lose the USA one.
There are stricter rules here on what can be used to get a case going. You can't just yell and shout opinions and start a court case here like in California. You have to show you have evidence of breaking the law.
Secondly IB would need to show that there are distinct issues to do with the UK jurisdiction, not covered by the USA case. The only item that applies to, is the employment agreement VB made with UK residents.
However British courts support the right of a skilled craftworker to use their skills to make a living. In this case that means coding forums, and associated business skills.
There is some support for one year agreements not to compete but even that is not set in stone. Employment is king b ecause our asithorities dont want lots of people pushed into poverty claiming benefits because they are legally banned from making a living. Nor do they want companies denied the skills of good craftspeople.
So a UK case is extremely unlikely.
