출애굽기 23:6의 Halakhah

To not tip the judgment of an evildoer: To not tip the judgment of one of the litigants when one knows that he is an evildoer and a master of sin, as it is stated (Exodus 23:6), "You shall not sway the judgment of your destitute in his quarrel." And its explanation is that he is destitute in commandments, as its understanding is not that he is destitute in money; since it is not necessary to say that he not sway the judgment against him, to steal from him in his poverty. Rather, we have been commanded that even though he is an evildoer, the judge should not say, "Since he is an evildoer, I will sway the judgment against him" - as the judgment of evildoers is for God, and not for you. And so is it in Mekhilta, "[If] an evildoer and a proper man stand in front of you in judgment, you might say, etc."
