Concerned with judge giving discharge (6)
I believe the answer is:
redeem
'discharge' is the definition.
(thesaurus)
'concerned with judge' is the wordplay.
'concerned with' becomes 're'.
'judge' becomes 'deem' (I've seen this before**).
're'+'deem'='REDEEM'
'giving' is the link.
(Other definitions for redeem that I've seen before include "Make good" , "Buy black, or convert into cash" , "Retrieve from hell or pawn" , "Pay off loans or promissory notes" , "Avoid pawn loss" .)
