Judges make decisions by decisions based on the appropriate laws. They then investigate to learn all the facts. Finally they make a decision. Under civil law, judiciary decisions are not a critical part of forming civil laws. Under Dutch civil law for example, there are so many civil laws that it becomes difficult for lawyers and judges to know if they have found all the laws that apply to a case. Even with all the laws, not every situation is covered. The civil court will research everything it can on the subject, then make a decision. For this reason those who start a legal case never know for certain what the decision will be.
