What constitutes 'domestic law'?

Domestic law refers to laws that are established and enforced within a specific country. This includes a wide range of legal norms such as statutes, regulations, and case law that govern the behavior of individuals and institutions within that jurisdiction. Domestic laws are created by a country's legislative bodies and are influenced by its constitution, legal traditions, and social values.

The other options highlight different aspects of law that are distinct from domestic law. International agreements, for example, pertain to treaties and conventions that nations enter into, which do not automatically constitute domestic law unless they are implemented through national legislation. Universal laws, while they may aim to address issues that affect all nations, are not laws that are enacted by a specific country, thus falling outside the definition of domestic law. Legal principles established by treaty apply to the parties involved in the treaty but may not have an automatic effect within the internal legal framework of a country unless specifically incorporated.

Understanding domestic law is crucial, as it forms the basis for legal rights and obligations for individuals and entities within a nation.
