Legal process shows sense (7)
I believe the answer is:
hearing
I believe this is a double definition.
'legal process' is the first definition.
(I've seen this before)
'sense' is the second definition.
(hearing is a kind of sense)
'shows' is the link.
(Other definitions for hearing that I've seen before include "Audition - trial" , "Trial; one of the senses" , "Perceiving sound" , "Trial before a judge" , "News" .)
