We can see law from two main perspectives. Law is either complex of written regulations, which are prepared by human beings based on some interests or it is a complex of rules, which altough are written, but its nature are originating from higher normative system.

What is not banned by law, is allowed. Though this law philosophy is leading to instability in society.
Every year legislator is making hundreds of amendements and create new laws to cover new circumstances which appear in the society.
