Appalling court order (6)
I believe the answer is:
direct
'order' is the definition.
(directing is a kind of ordering)
'appalling court' is the wordplay.
'appalling' becomes 'dire' (I've seen this in another clue).
'court' becomes 'ct' (abbreviation used in road names).
'dire'+'ct'='DIRECT'
(Other definitions for direct that I've seen before include "Outspoken" , "Frank; unambiguous" , "Guides do it" , "Frank; supervise" , "Straightforward; control" .)
