I am not an expert in UK law by any means but to me it seems a little odd that this case would go to the high court without first going to a lower court. also if the court grants an injunction then there's should be a publicly available document somewhere that people can view.
it also seems a little odd how this would happen so quickly given the nature of how slow courts are.

so I would be sceptical about these claims without first seeing actual documentation.

as I said.. I am no expert on the UK court system.. I just find it a little strange. I have seen a lot of multimillion dollar bitcoin scams with the authorities and victims doing very little to chase down the scammers.

if this is a case where one set of victims have taken firm and decisive action then I am all for it but this could also mean that our coins get tied up in the UK court system for a long long time and they will end up getting paid out first while everyone else who is not part of the legal action gets to wait for the leftovers.
