Instruments for court officials (9)
I believe the answer is:
recorders
I believe this clue is a double definition.
'instruments' is the first definition.
(recorder is a kind of instrument)
'court officials' is the second definition.
(recorders are officials in courts)
'for' acts as a link.
(Other definitions for recorders that I've seen before include "Woodwind instruments" , "Tubular wind instruments" , "Judges" , "Music producers" , "musical instruments" .)
