Anjouan,
PANS-OPS vol 1/2 are only the approach engineers/pilots guide on how apporaches should be constructed.
The legisalture you fly under (FAR-121/135/JAR-OPS1) determine how and if you should fly these approaches.
Thus, JAR-OPS1 will not allow you to continue beyond the OM (or equivalent point) unless you meet operational approach minima (as defined under JAR-OPS, but not lower than state minima).
keithl, IMHO a circling apporach requires ceiling to be taken into consid, but I may be wrong
Brgds,
