Obeying the law is the basic demand of constitution of any country from its citizens. It is basically following the general rules of being the citizen of country.
Ethical behavior is about being morally right in your actions, it is no where defined properly what is ethical, sometimes even unethical behavior does not count in illegal behavior.
