Ease up on the posts old chap. You were utterly wrong about the CAA earlier (as you now see) and now your assertion that it is just the FE is equally questionable. At every half decent FTO, somebody (maybe the CFI, maybe Ops, maybe the owner) will have records of instructor/examiner currency, which will be kept up to date and regularly checked.
The FE will be only wholly to blame if he:
a. Is a lone wolf, operating as sole trader.
b. Has wifully misled his employer.
What's more, even if it is b. (above), the OPs beef will still legally be with the FTO (ie the trading company) and not with an employee of such...it is the law in the UK.
There is nothing complicated about this unless the FTO choose to make it so. In which case that is what the Small Claims Court is for, and it works!
As for the CAA, whatever they may or may not be guilty of, all they have done here is their job. And by catching this in a timely manner, they have potentially stopped all manner of future grief for the OP.
