B) Customary Rules
C) General Principles
D) Judicial decisions and scholars

Hierarchy?

There isn't one, but some argue there is a difference in formal and material sources. Formal being the ones which create binding rules (Treaties) Material being ones which seemingly come from the other sources of law. Akehurst points out that when writing it they decided against having a hierarchy.

4

Treaties highest source?

Lautherpact believes so as States must express consent into the treaties from them to have effect.

5

Unmentioned Sources?

Unilateral Declarations - Nuclear Test case (France)
Soft Law - 'in the twilight between politics and law'
Jus Cogens - Normal norms

Treaties and Conventions

Determined by Vienna Convention on the Law of Treaties.
2(1) definition β€˜an international agreement concluded between States in written form and governed by international law, whether embodied in a single instrument or in two or more related instruments and whatever its particular design.’
Art 26 relies on pacta sunt servanda, which means only bind parties involved in it
Binding force of a treaty comes from the consent
Art 34 - No obligation for third parties, yet UN Charter and ICC Statute too important (Arrest Al-Bashire)

Types of Treaties

Multilateral - law-making lay down universal rules
Bilateral - Agreements between two states, specific matters

State Practice - 'constant and uniform usage, accepted by law' Asylum Case, 3 elements - Consistency, Durability (Not important though can impose quickly) Generality (general acceptance)
Persistent objector - New norms, Asylum case (Peru) Fishers Case (UK v Norway)

General Principles

Judicial Decisions

Art 59 'No binding force' No precedent, it is in order to prevent principles being established. Can reference other courts decisions, Arrest Warrant case domestic courts referenced

Publicists

More likely to refer to International Law Commission than publicists now. Nottebohm case

Jus Cogens

More bindings than normal norms, relate to slavery/genocide. ICJ have refused to make a list of them, Nicaragua case 'prohibition of use of force as Jus Cogens'

14

UNGA Resolutions

Not legally binding, but can be evidence of customary rules. Even if majority agree does not mean things will get done about it Nuclear disarmament

15

Unilateral Declarations

Must be from a legitimate source of authority, made publicly and intention to declare

16

Soft Law

Global and Formal - UNGA Resolutions/Declarations
Regional and Non Formal - IMO Guidelines, Recommendations
They can affect future sources, and sources rely upon them.
Against - It cause confusion, it's not law or non-law, merely recommendation
For - It's flexible, relative normality within IL,

Treaties always binding?

Whilst some treaties may seem to bind, they use soft law language in order to make sure that they are technically not bound by it Paris Agreement Art 4(2) shall pursue domestic measures of achieving aims
