For this reasons, the International system relies heavily on the support it receives from regional human rights systems. Support also comes from Governments and from non-governmental organizations. And each of this groups has a special role to play in the development of a universal culture of human rights. Non-governmental organizations, for example, by their very nature, have a freedom of expression, a liberty of movement, and a flexibility of action which allow them to perform tasks, which Governments and international organizations are unable or may even be unwilling to perform. The role of national Governments in the realization of human rights is particularly important.
Human rights involve relationship among individuals, and between individuals and the state.
Therefore, each state must be responsible for the practical task of protecting and promoting human rights. At the national level, human rights can be best protected through adequate legislation, an independent judiciary and the establishment of democratic institutions. When states ratify a human rights instrument, they either incorporate its provisions directly into their domestic legislation. Therefore, universal human rights standards and norms today find their expression in the domestic laws of the great number of countries. However, the existence of laws concerned is not enough if these laws do not also provide the institutions necessary to ensure their effective realization.
