Fair court system: courts show no favoritism or bias, but enforce justice impartially
The courts are the primary means for guaranteeing that everyone in a nation is subject to the rule of law. But if the judges are corrupt and use their power to favor certain people (such as government officials or wealthy and powerful friends), then business investment is discouraged (because of the risk that the relative of a judge could defraud a business owner without fear of punishment) and the economy is hindered from producing more goods and services. Therefore, a fair court system is important for guaranteeing that leaders will use their power for the benefit of the people as a whole.
The Bible strongly emphasizes that judges must be fair and not pervert justice:
You shall appoint judges and officers in all your towns that the Lord your God is giving you, according to your tribes, and they shall judge the people with righteous judgment. You shall not pervert justice. You shall not show partiality, and you shall not accept a bribe, for a bribe blinds the eyes of the wise and subverts the cause of the righteous. Justice, and only justice, you shall follow, that you may live and inherit the land that the Lord your God is giving you. (Deut. 16:18-20)
Judges were not to show favoritism to the poor: “nor shall you be partial to a poor man in his lawsuit” (Ex. 23:3). However, neither were they to show favoritism to the rich and thus act with bias against the poor: “You shall not pervert the justice due to your poor in his lawsuit” (v. 6).
