Court intervention to close juice (6)
I believe the answer is:
nectar
'juice' is the definition.
(I know that nectar is a type of fruit juice)
'court intervention to close' is the wordplay.
I cannot really see how this works, but
'court' could be 'ct' (abbreviation used in road names) and 'ct' is present in the answer.
'close' could be 'near' (similar in meaning) and 'near' is present in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for nectar that I've seen before include "Sweet fluid produced by flowers" , "Sweet liquid secretion to attract pollinators" , "Divine drink" , "Ambrosia" , "Drink of the gods in Greek myth" .)
