National laws, also called domestic law, are laws that exist within a particular country. Domestic laws can be Federal (affecting the whole nation) or State (affecting a specific State). They include primary laws (Acts) and secondary laws (regulation) that allow the primary laws to be implemented and enforced. National laws establish and govern the ways in which child protection and care systems function in each country and the way services are to be provided. However, domestic legal systems are also influenced by a State’s international obligations. Some countries must pass domestic laws to incorporate their international obligations into the domestic legal system (as a State party to the Convention on the Rights of the Child for example). Other countries recognise treaties as part of their domestic legal system without incorporation. Therefore, the link between international law and domestic law is an important one to understand with respect to child rights and child protection and care at the national level.
