Judicial investigation makes sense (7)
I believe the answer is:
hearing
This clue might be a double definition.
'judicial investigation' is the first definition.
'hearing' can be an answer for 'investigation' (hearing is a kind of investigation). I am unsure of the 'judicial' bit.
'sense' is the second definition.
(hearing is a kind of sense)
'makes' is the link.
Can you help me to learn more?
(Other definitions for hearing that I've seen before include "Trying" , "Earshot; trial" , "Trial; sense" , "Trial; one of the senses" , "News" .)
