Passing comments — final notice before a direct broadcast (6,5)
I believe the answer is:
obiter dicta
'passing comments' is the definition.
('obiter dictum' can be a synonym of 'passing comment')
'notice before a direct broadcast' is the wordplay.
'notice' becomes 'obit' (I've seen this before).
'before' is a charade indicator (letters next to each other).
'broadcast' indicates anagramming the letters.
'direct' is an anagram of 'erdict'.
'a' after 'erdict' is 'erdicta'.
'obit'+'erdicta'='OBITER DICTA'
'final' is the link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for obiter dicta that I've seen before include "Incidental remarks by judge" , "Departures" , "Mentions" , "comments from the judge - with 7d" , "passing remarks" .)
