Legal case resulting from instruction to shoot (6)
I believe the answer is:
action
I believe this is a double definition.
'legal case' is the first definition.
(thesaurus)
'instruction to shoot' is the second definition.
('action' is an instruction to shoot on a film set)
'resulting from' is the link.
(Other definitions for action that I've seen before include "Carry out" , "It is said to speak louder than words" , "Deed or legal proceeding" , "war?" , "Watch operating mechanism" .)
