Justice Alito (6)
I believe the answer is:
samuel
'justice alito' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for samuel that I've seen before include "XWD SETTER" , "Old Testament judge and priest" , "Two books of the Bible bear this name" , "First name of Beckett, Irish writer" , "Prophet, anointed King David" .)
