Judging righteous judgment is the act of righteous people. The duty is always to judge with righteousness and to properly judge between evil and good.
The guilty person, whether the rightly accused or whether it be the false witness, he shall not go unpunished. And Leviticus warns even further the danger of unwittingly or unknowingly breaking the commandment and doing harm to someone else. Even he or she shall feel the hand of the Lord’s wrath.
