The question seems to have a formatting issue with repeated terms. However, based on the context, it is clear that you want to identify which option listed is not a major source of law.
The main sources of law typically include:
- Constitutional Law - laws derived from the constitution.
- Statutory Law - laws enacted by legislative bodies.
- Case Law (or Common Law) - laws established by the precedents set in court decisions.
Given the options listed, "Ethics" is not a major source of law. Ethics refers to moral principles that govern a person's behavior or conduct but does not constitute a legal source of law in the same way as the others mentioned.
Therefore, the answer is Ethics.
