Unscrupulous type in court. No conclusion reached (7)
I believe the answer is:
chancer
'unscrupulous type' is the definition.
(someone who exploits opportunities)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for chancer that I've seen before include "One taking risks" , "Informally, one who tries his luck" , "Unscrupulous opportunist" , "opportunistic sort" , "Unscrupulous sort" .)
