Awareness of court decision — one’s going inside (9)
I believe the answer is:
sentience
'awareness' is the definition.
(sentience is being aware or conscious)
'court decision one's going inside' is the wordplay.
I cannot quite understand how this works, but
'one' could be 'i' (Roman numeral) and 'i' is found within the answer.
'decision' could be 'sentence' (I've seen this before) and 'sentence' is located in the leftover letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'of' acts as a link.
Can you help me to learn more?
(Other definitions for sentience that I've seen before include "Ability to feel things" , "Ability to feel or perceive" , "Feeling" , "mind" , "awareness" .)
