Generally, public international law, or the body of laws governing relations between nation-states. International law deals with the legal responsibility of states in their conduct with each other. International law is also used to govern issues relating to the global environment, the global commons such as international waters and outer space, global communications, and world trade. But international law can also be concerned with the treatment of individuals within state boundaries. Some international treaties, for example, those regarding refugees or war crimes, are binding on the Government of Canada when incorporated into Canada’s legal system. Further, international human rights, a relatively new sub-set of international law, outlines the rights of individuals against a government either in the country where they are a citizen or where they reside.
