Definition
To judge and enforce the law with complete fairness, impartiality, and integrity.
How it's used
Originating from the tradition of hanging a plaque with these four characters in old Chinese courtrooms, this idiom carries a formal and slightly literary weight. While it describes a judge or official, it is also used metaphorically to praise someone for being completely transparent and unbiased in their decision making. It is rarely used in casual, everyday small talk, appearing more often in news reports, formal speeches, or when discussing legal matters.

Common mistake
Learners often mistake this for a common adjective describing any fair person, but it is specifically tied to the context of authority, judgment, or official oversight. Using it to describe a friend splitting a dinner bill or a teacher grading a simple quiz sounds overly dramatic and out of place.
