Allure of court case (6)
I believe the answer is:
appeal
I believe this clue is a double definition.
'allure' is the first definition.
(I've seen this in another clue)
'court case' is the second definition.
(e.g. appealing against a sentence)
'of' acts as a link.
(Other definitions for appeal that I've seen before include "Take case to higher court for review of verdict" , "Claim - fascination" , "Attraction - legal process" , "Attraction, pleasantness" , "Request for charity donations" .)
