"Follow #justice" in #deuteronomy 16:20 implies an active process of seeking out where righteousness leads and going after it. The word radaf can also be translated "pursue". The intent is that a judge is to pursue (through study, prayer, investigation, testimony, etc.) what *God* says is justice, not what the judge feels it ought to be. God's courts of justice do not allow judicial activism except that which promotes repentance and obedience to #torah.
