Rescind newly-issued notice (7)
I believe the answer is:
discern
'notice' is the definition.
(thesaurus)
'rescind newly-issued' is the wordplay.
'newly-issued' is an anagram indicator.
'rescind' with letters rearranged gives 'DISCERN'.
(Other definitions for discern that I've seen before include "Pick out" , "See" , "Espy" , "Recognise, find out" , "Notice" .)
