noun
unscrupulous lawyer; shyster; crooked lawyer
Pejorative term for a lawyer who acts unethically, often for personal gain. 'Shyster' and 'pettifogger' are dated or rare in modern English; 'unscrupulous lawyer' is the most neutral equivalent.
あの悪徳弁護士は依頼人から法外な報酬を要求した。
That unscrupulous lawyer demanded an exorbitant fee from the client.
