The most common type of class action is a shareholder class action when a company fails to disclose something bad on time and then when it comes out later the share price drops.
Despite the fact that it is mathematically impossible to prove any probability for a single correlation event like this, Courts have found causation and damages. The standard is only balance of probabilities (50.01%).
I have 4 bans and 4 very large drops which are mathematically very strongly correlated (99.999%) and have no other plausible explanation.
All other similar or larger drops over 5 years have a clear outside explanation.
Its a much stronger case on damages than people realise.
Ah wow that sounds very promising.
I forgot how much different civil law is vs criminal.
