The CAA exam papers haven't been updated in quite a while.
With EASA regulations in place, but the CAA still issuing JAR-FCL licenses (which are "deemed" EASA-FCL licenses anyway), I can well imagine that the CAA Air Law exams are actually outright wrong at the moment.
But I can also imagine that it's exceedingly difficult to come up with a new set of Air Law exam papers right now that are right, and will be right in the upcoming few months, while all sorts of supporting EASA documents have not been published (including Acceptable Means of Compliance and such).
So if you're a PPL student at the moment: Ignore what is actually the law at the moment. Study the Air Law book that goes with the CAA exam papers, and simply assume the ANO is still in effect in full. It may sound odd, but learning outdated information might be the only method to gain a pass, at this very moment.
Or wait until EASA-FCL is well and truly established, all details have been published and implemented, and a new set of exam papers has been issued. I don't know the exact date, but it'll probably be somewhere end of this year earliest.
"Caught between a rock and a hard place" comes to mind. But that doesn't apply just to students. I would not want to be working for the CAA at the moment.
