If you get your publicity right you should embarrass the CAA enough to cause them to drop the case.
Basically they are arguing that the guy should have been left to die just to fulfill their rules.
And if that is the case and they did as the CAA requires are they then guilty of failing to render assistance?
Might be an interesting argument. Just because your license is suspended doesnt mean he wasnt capable of rescuing the guy as has been shown.
