Hate being charged before endless tribunal (7)
I believe the answer is:
rancour
'hate' is the definition.
(rancour is a kind of hate)
'charged before endless tribunal' is the wordplay.
'charged' becomes 'ran'.
'before' means one lot of letters go next to another.
'endless' means to remove the last letter.
'tribunal' becomes 'court' ('court' can be a synonym of 'tribunal').
'court' with its last letter removed is 'cour'.
'ran'+'cour'='RANCOUR'
'being' acts as a link.
(Other definitions for rancour that I've seen before include "Hard feelings" , "Bitter feeling or ill will" , "Malice" , "Antipathy" , "Bitterness and ill will" .)
