Homeguard,
I do not wish to get into an argument with you or anyone else over this but I do think you have your wires crossed re: EASA and its powers.
I do not speculate but base my comments on published CAA documents.
JAA was never a regulatory authority as such, hence the reason national aviation authorities (NAAs) could make their own rules should they so wish and of course they often did. Legal authority and responsibility laid with each individual NAA and each country occasionally made its own rules, however, in the main most stuck to the agreements outlined within JARs.
Similarly, ICAO is not a legal authority with regulatory powers over individual member states, however, membership of ICAO requires compliance with certain established procedures. Again though, deviations to ICAO rules were possible, subject to ICAO agreement, but legal authority rested with individual NAAs.
EASA is a different kettle of fish. It was recognised that, in order to obtain EU cross border compliance full legal regulatory authority within EU was required and as such EASA has been granted the status of a higher executive body within the EU, i.e. it has full legal clout across all member states. Individual states may have their own legislation, e.g. Air Navigation Order, but these would either endorse or ratify EASA regulations.
The new instructor rating under consideration by the UK National PPL Policy & Steering Committee is for a Simple Single Engine Aircraft (SSEA) rating and would only be related to the NPPL and not the JAA PPL, therefore, it is a daytime VFR licence only and restricted to the NPPL maximum weight for SSEA of 2,000 kg.
It is also expected that the UK NPPL will cease when EASA assumes full regulatory authority for FCL and it is presently unclear what EASA licence will replace it, probably something along the lines of a Recreational Pilot or Sports Pilot licence.
Saying that, EASA has formed a sub committee which is looking at the possibility of introducing a pan-EU Light Aircraft Pilots Licence with appropriate instructor ratings.
Hope this helps clarify things.
