Conclusions in hard case came from judge (4)
I believe the answer is:
deem
'judge' is the definition.
(thesaurus)
'conclusions in hard case came from' is the wordplay.
'conclusions in' suggests the final letters.
The last letters of 'hard case came from' are 'DEEM'.
(Other definitions for deem that I've seen before include "Regard in a specific way" , "Judge in redeeming" , "Regard, consider" , "Believe" , "View as" .)
