Public International Law Week 2 Flashcards
Positivism
Rules of law binding upon states emanate from their own free will. States act as authorities in making international law and make international law together.
Voluntarism
Rules of law bind states emanate from their own free will, by being party to a treaty, accepting international law, following norms of international law, etc. When a state concludes a treaty voluntarily, it is an act of sovereignty.
Consensualism
International law is based on state consent to the treaty.
How to use the sources of international law in coming to a decision?
1) Go to the treaty (38(1)(a) ICJ Statute)
2) Go to customary International law (38(1)(b) ICJ Statute)
3) Go to general principles of law (38(1)(c) ICJ Statute)
4) Go to judicial decisions and writings of scholars (38(1)(d) ICJ Statute)
Other sources of law outside of Art 38 ICJ Statute?
UNSC decisions (binding), UNGA decisions (not legally binding but can reflect CIL), unilateral declarations of states intending to pose an obligation.
When does a treaty become binding upon a state (entry into force)?
Usually, once the state ratifies the treaty. However, can also state in the treaty that it is binding upon signature - this is used to circumvent parliament.
Pacta sunt servanda
Art 26 VCLT - every treaty in force is binding upon parties and must be performed by them in good faith.
Art 34 - 37 VCLT
Concerns treaty rights and obligations for third-states.
Art 46 - 64 VCLT
Concerns invalidity of a treaty.
Art 18 VCLT
Before the treaty enters into force, but during the process of ratifying/signing the treaty, the state(s) have an obligation not to act in a way that defeats the object and purpose of the treaty.
Non-retroactivity of VCLT
Art 4 VCLT: The VCLT rules only apply to treaties concluded by States after entry into force of the Convention with regard to such States (as parties to the Convention). Hence, any treaty concluded before 1980 (when the VCLT became in force), the VCLT does not apply but rather must use CIL.
Two elements of CIL
General practice - Material element
Opinio juris (accepted as law) - subjective element
Criteria for general practice
Widespread, Uniform, Representative, Constant (WURC)
Repetition: it must be followed, used, applied repeatedly, consistently, and constantly.
E.g., Legislation of a state, what they have been doing physically, etc.
Essentially, states accept a certain custom when they engage in practice that is uniform in its behaviour and engage in practice over a period of time.
Criteria for opinio juris
Renders relevant practice legal, as undertaken with a sense of legal obligation. It differentiates customary international law from rules of etiquette, morality, politically expedient behavior, etc.
E.g., statements of government, state conduct that shows it considers a certain obligation as legally binding, etc.
What is the main purpose of general principles of law
Mainly used in the case of filling in gaps. If there is not convention nor CIL, then can use GPL to provide an answer or supplement Convention and CIL.
E.g., the principle of good faith - as mentioned in Art 2(2) UN Charter and other Court decisions is a general principle of law.
Judicial decisions/doctrine
Subsidiary means made for the determination of the rule of law. Both national and international courts and tribunals can render decisions which we can use, but national court decisions are only useful if they apply international law.
Must use court decisions subject to Art 59 ICJ Statute - there is no stare decisis (precedence) in Court decisions.
Primary sources of law
International conventions, customary international law, and general principles of law.
