An “act of aggression” has been defined as “the use of armed force by a State against the sovereignty, territorial integrity or political independence of another State, or in any other manner inconsistent with the Charter of the United Nations” (Art. 8bis (2)), i.e., without the justification of self-defense or authorization by the Security Council. The definition contains a list of seven acts of aggression (for example, invasion by
armed forces, military occupation, annexation by the use of force, bombardment and blockade of ports) that are identical/influenced by the UN General Assembly resolution 3314 (XXIX) of 14 December 1974 on the definition of Aggression.
