I am loathe to add more to a total non-event, but there is a world of difference between what a pilot is currently certified to be able to do by the relevant CAA and what a pilot is actually able to do.
I'm sure with 30 years experience the pilot in question has been CAT II qualified many times over and will have made numerous approaches in CAT II conditions over the years. It is just his/her bad luck that on the day in question their licence did not have the necessary legal CAT II validation.
For those wondering what if there was an emergency and they had to land in the fog, simple - they would have landed in the fog. Just because the paperwork may not be correct, does not mean a pilot suddenly loses the ability to fly.
