Public International Law Week 1 Flashcards
Natural law
Law is divine and either ordained by God or through reason.
Legal positivism.
Law is created by men.
Hugo Grotius
‘On the law of war and peace’ - where there is society, there is law. The association which binds together the human race, or binds many nations together, has the need of law.
Thomas Hobbes
‘Leviathan’ - state of nature is one in which there is no common power/authority. People are left to their own devices and cannot rely on state authority. The condition of man is called ‘Warre’ in which every man is against every man.
John Locke
In the state of nature, there is a lack of established, settled, known law, and a lack of indifferent judges. Introduced the separation of powers.
Subjects of international law
Those who make the law and determine, apply, and enforce the law
International legal positivism
Centred around the idea that ‘men make the law.’
John Austin’s idea of International legal positivism
International law is not law but rather positive morality because there is no common rationality in international law. If one state tells another state to do something, there is no law to back it, so it is backed by morality. Law depends on the sovereign who has power to enforce it.
Hans Kelsen’s idea of international legal positivism
There is no sovereign, but when international law is violated states may do two things: reprisal or war
Reprisal
responding to an unlawful act with an unlawful act that is thereby justified
HLA Hart
A legal system has two types of law - primary law and secondary rules. International law only has primary law, and you need secondary rules for a legal system. Thus, international law is not a legal system due to absence of secondary rules.
Primary law
Rules which create obligations and rights for subjects of law.
Secondary rules
Dictates who can create, interpret, apply, and enforce the law.
Leslie Green, Thomas Adams
Law is a matter of what has been posited. The law is the law because it is the law - does not need to be fair just, wise, efficient, etc. to be the law.
ICJ Barcelona Traction Case
“In particular, an essential distinction should be drawn between the obligations of a State towards the international community as a whole, and those arising vis-à-vis another State in the field of diplomatic protection. By their very nature the former is the concern of all States. In view of the importance of the rights involved, all States can be held to have a legal interest in their protection; they are obligations erga omnes (to everyone).”
