Government error (9)
I believe the answer is:
oversight
This clue is a double definition.
'government' is the first definition.
(thesaurus)
'error' is the second definition.
(I know that oversight is a type of error)
(Other definitions for oversight that I've seen before include "Innocent mistake" , "Supervisor's charged with this" , "Mistake resulting from inattention" , "Failure to notice - blunder" , "Shot giver due to unintentional omission" .)
