Unethical lawyer (7)
I believe the answer is:
shyster
'unethical lawyer' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for shyster that I've seen before include "Unscrupulous dealer" , "Wheeler-dealer" , "Informally, an unscrupulous or unprofessional person - sounds bashful?" , "Suspect lawyer" , "One using discred-itable methods" .)
