Honest Judges

The Torah commanded that there be שופטים ושוטרים, judges and policemen, in all of your gates. They were to judge the people with correctness and righteousness.
The Torah warns of the danger of taking bribes and showing favoritism in judgement. One should not feel sorry for the poor litigant, or sway decisions in favor of the wealthy.
Great care should be taken by those empowered to choose the judges of a particular place. These judges must be the most upright, G-d fearing, members of the community.
When courts render the correct decisions, they are merely confirming that which was decided by the Heavenly courts. This is why the Rabbis said that judges become partners with Hashem in creation, when they decide matters correctly. They are maintaining the world order as it should be.
The Chazon Ish referred specifically to matters of judgement, when he expressed his concern about the individual who might feel that he has mastered his character flaws. He might mistakenly feel that he knows compassion better than those qualified to judge.
This is why one must combine intense Torah study with perfecting one’s character. It will be clear that real justice is in the hands of those qualified. They also have great compassion in how they conduct themselves.
The ultimate purpose of having a fair and honest judicial system, is that it will allow us to merit inheriting the land. The שופטים ושוטרים will insure that the laws are being observed, and they will enforce the decisions of the courts.
