Of course I am fishing... But don't worry, I don't use baits nor nets... Just read and forget ;-).
I am curious and thinking that you have a problem with civil law. The problem is that their is fundamentally 2 kind of common law... (Before your bibles stories)... Nomadic and sedentary... Own share it earth the other privatize it through his work... One hunt the other farm... Hard or impossible to be nomadic nowadays.
There are as many kinds of common law as there are communities. Same with civil law if the community has civil law. But they are quite similar in some fundamental ways, because people are quite similar in fundamental ways - need air to breathe, water to drink, food to eat, clothing, shelter.
Civil law becomes dictatorship by government. When the governing dictatorial body is wise, it is a strong government, beneficial to the people. When the governing dictatorial body is foolish, it harms the people.
When the common law group has wisdom and understanding, they use the people (jury) to judge how much harm or damage has been done in a case. Otherwise everybody is free. If the common law group is foolish, they judge cases foolishly hurting people of the group thereby.
Good civil law can organize the people for projects better than the common law can. An example of this is the civil law government of the United States being organized to fight the common law American Indians. The Indians were common law people with little civil law. No Indian could force another Indian to fight in a battle against U.S. soldiers. So, whenever an Indian thought he had enough fighting, he simply went home. The U.S. solder was not allowed to go home because of civil law.
This means that civil law has strength, but common law has freedom.
The United States of America has strength because it has civil law that is or can be overruled by common law. No matter how corrupt the civil law U.S. government becomes, the people can stop it using common law. The common law jury can override any law that the civil law government makes. But the civil law government can direct the people with any law up until the people bring common law into play.
Good combination, civil law ruled by common law.
The problem in America is, some government people have hidden the common law part from most of the people. The people don't realize that they can be free from governmental coercion using common law. But, the people are waking up.
