The muddy situation clears somewhat-and I may now be answering my own question!!
Further investigation reveals that there is a "conflict" between those airlines operating per CAP168 and those who are more realistically now on JAR-OPS.
As Data Dad says, these lucky people must adopt a non precision minima whilst this does not apply to those operating JAR-OPs. These lucky folk can simply adopt the normal ILS minima.
You'll be delighted to know DD that as I write, the Airport Authority are replacing the miscreant generator, though it will mean a total airfield closure whilst they do it.
Hopefully this will solve the problem- at least for those involved at our far end of the universe.
