As an ATCO (retired), for many years I had no direct & official knowledge of what the legal limits for the pilots of an aircraft to continue an approach were. I had a general understanding of the pilots’ limits, but no official understanding & involvement (or policing) of the legislation. I simply provided the met’ data to the pilots & let them get on with doing their job - on the understanding that they knew what they were doing. During the latter part of my time, we were required to inform aircrew when conditions were below the limits for an approach, & to advise them that, if such an approach was made, we would be obliged to report the matter. I do not know if things have moved on & whether ATC now has the authority to forbid an approach “below limits”.
