AGGRESSION ȃ THE SUPREME INTERNATIONAL CRIME OR NOT A CRIME AT ALL?
confirmed that those below this level cannot be held accountable for aggression and
it is generally to be expected that the crime would mainly be invoked with respect to
high level officials.
Thirdly, the political nature of the crime of aggression stems from the special role
ascribed to theUNSecurityCouncil in the determination of whether an act of aggression
has occurred. This role is codified in the UN Charter which vests the Security Council
with the
“permanent responsibility for the maintenance of international peace and security”
(Article 24). Assuming this primary responsibility, the Council shall
“determine the
existence of any threat to the peace, breach of the peace or
act of aggression
”
(Article 39,
emphasis added) and decide upon adequate political, diplomatic, economic or, in the
extreme case, military measures to re-establish peace and security.
The special role of the Security Council is partly recognized in the Rome Statute.
Under Article 15
bis,
the prosecutor intending to open an investigation in respect
of a crime of aggression has to
“first ascertain whether the Security Council has made
a determination of an act of aggression committed by the State concerned”
(par. 6).
When this is not the case, the prosecutor may proceed with the investigation on the
authorisation of the Pre-Trial Division, provided the UN Security Council does not
request the deferral under Article 16. Article 15
ter
adds that
“a determination of an
act of aggression by an organ outside the Court shall be without prejudice to the Court’s
own findings under this Statute”
(par. 4). The ICC is therefore not
stricto sensu
bound
by the determination of the Council made under Article 39 of the UN Charter,
though it is likely that it would not deviate from it without very serious reasons.

In
prosecutions at the national level the role of the UN Security Council would have to
be decided upon on an
ad hoc
basis.

The only prosecutions of this type which have
so far taken place, those relating to WWII, did not have to deal with this question,
since the occurrence of an act of aggression (by Germany and Japan) was established
by the Nuremberg and Tokyo Tribunals.
The political nature is obviously not reserved to the crime of aggression. The
other international crimes might reveal, and often do reveal, the elements described
above as well. This is well exemplified in some of the cases prosecuted by the ICC,
for instance the case of the Sudanese president Omar al-Bashir, accused of genocide,
crimes against humanity and war crimes. Yet, what might appear with respect to the
other crimes occasionally is a rule for the crime of aggression. Moreover, the three
elements politicizing the crime are present simultaneously, making any prosecution
for aggression inherently political. That also explains why granting the ICC the
jurisdiction over aggression has been much more controversial than granting it that

Prosecution for the crime of aggression at the national level would however mostly be prevented either
by political reasons or by immunity.
