My opinion carries very little weight. My point is that the CAA says in LASORS "FI will sign the applicants logbook" while JAR-FCL (as quoted in your post) says that the flight has to be with a FI or a CRI. There is no requirement under JAR-FCL that the instructor MUST hold a FI rating.
You know and I know and the JAA knows that the flight has to be signed off in the log book by the instructor and that the instructor can hold a FI or a CRI rating. The author of LASORS may have written something different but that doesn't change the law or the regulations.
What point is it you are trying to make?
