you can no doubt answer a question I have long wondered about.

What information does the controller have at his immediate disposal
that an approach is not authorized?

Are they just supposed to have an awareness, or is there some listing
at their radar stations that show NA approaches?

(I was once nipped by poor preflight planning when I was informed by
the approach controller that an approach I wanted was FDC NOTAM'd
"not authorized at night". Much scrambling. Never forgot to check
FDC NOTAMS again after that)

It's not "apparent" the aircraft was "cleared for a deauthorized approach
by ATC" at all.

If the controller used the phraseology "CLEARED APPROACH" it was up to the
pilot to select the instrument approach.

That doesn't include an approach that was known (or should have been known
through a proper pre-flight) to be OTS.

It's apparent the controller did not use the phraseology "CLEARED APPROACH".
From the NTSB report:

"At 1145:15, the controller stated, "november seven four charlie charlie,
cleared for the s d f approach to uh somerset, maintain four thousand until
your established on the approach." The pilot replied, "ok maintain four till
established (unintelligible), thank you four charlie charlie." The
controller then repeated the approach clearance and this time specified the
SDF RWY 4 approach, and the pilot again repeated that he was to maintain
4,000 feet until established and was cleared for the SDF RWY 4 approach at
Somerset."
