Well first off, it's illustrated to me just how difficult it is to find a specific NOTAM on the AIS site (if you don't really know what it's about)!
Second, it's a most peculiar NOTAM that doesn't seem to make much sense to me. Nonetheless it's there and rules is rules - if a pilot elects to make an instrument approach and the visibility is below the absolute minimum ten the controller gives the pilot a warning and fills in the form.
Sorry.
