What is the Explanation of the text of art. 2(4) UN-Charter? --> 'international relations'
Explanation of the text of art. 2(4) UN-Charter:
“International Relations” = interstate use of force. So this does not conclude the states of one state within its territory against its own people.
What is the Explanation of the text of art. 2(4) UN-Charter? --> 'force'
“Force” = this prohibition captures every threat or use of armed force (from one state to another state).
There are forms of direct and indirect force:
→ Direct armed force; the use of force regulated by the regular armed forces of one state.
→ Indirect armed force; a state's use of force through other actors (like rebel groups (contras), another states,
private individuals)
What is the explanation of the text of art. 2(4) UN-Charter? --> “Against the territorial integrity or political independence…”
“Against the territorial integrity or political independence…” = this phrase is meant to particularly grave situations in which the use of force is being used. It is not meant to limit the scope of article 2(4) (you can see that in the manner “in any other manner…”), but it is meant to make clear that the prohibition applies in other instances where there is not perhaps a threat of political independence or territorial integrity.

What is The Law of Armed Conflict (jus in bello) (International Humanitarian Law/Law of War)?
What is the legal basis of the law of armed conflict?
- The sources of law are quite different from the law on the use of force: 1949 Geneva Conventions, additional protocols, other treaties, customary international law.
- Again, treaty law and customary international law are existing parallel next to each other.
Does the Law of Armed Conflict also aply if parties of a conflict have iniatlly entered the conflict in a lawful matter?
When does the LOAC apply for non-international Armed Conflicts?
Who can participate in hostilities? → Combatants vs Civilians. A distinction needs to be made between:
2. Unlawful Combatants
What are lawful combatants?
Is someone who can lawfully participate in hostilities (=vijandelijkheden). Because this person is a lawful combatant, when they get captured, they need to get the ‘prisoner of war’-status. They also can not be prosecuted for their conduct (=their participation in war) by the other side.
There are two types of lawful combatants;
- Regular armed forces (GCIII Art 4(A)(1)): these people wear uniforms (easy to recognize).
- Irregular, Lawful Combatants (GCIII Art 4(A)(2); see also API Art 44(3)): not part of the regular armed forces of the state. (for example; in the Ukraine there were foreign veterans that travelled to the Ukraine to fight Russia, and could be qualified as irregular, but still lawful combatants).
What are unlawful combatants?
→ Unlawful Combatant
An unlawful combatant is a civilian that participates in hostilities.
Such a civilian is not entitled to prisoner of war status,
when captured by the other side. They can indeed be
prosecuted by the other side for their participation in hostilities.
For the distinction of lawful combatants, take a look at GCIII Art. 4
In practice, this distinction is often a problem, where lawful
Combatants are not recognized as lawful combatants.
Who/what can be attacked during an armed conflict? What is a legitimate target?
