Re: Sueing a flight school in America
I think that you have given a sufficient outline of the school that many of us will have a good idea who we are talking about, and can probably sympathise with some of your likely concerns.
If your objective is truly not financial gain, and you simply wish to see the school lose its JAA qualification, then a lawsuit is not an appropriate course of action. The only organisation that can remove the qualification is the CAA, and your best course of action is to present them with a well-documented complaint, for their action. Your launching a Lawsuit does not in any way engage the CAA in the process, and your lawsuit in general terms, can only really be for the purposes of receiving personal damages of one sort or another.
So... IMHO... if you are doing this for the reasons you say, unhire the lawyer(s), put your gripe together in the form of a detailed dossier for the CAA. Engage the assistance of other students if you feel that additional evidence is needed to support your case, then present it to the regulator.
If you have enough evidence to support your case, they will act, and your claimed mission will be accomplished at very little personal cost.
Anybody coming to a case saying that they "have the support of a national newspaper", tends to lose a certain amount of sympathy. What exactly do you think that their involvement is going to achieve?
