The crimes
The Court's founding treaty, called the Rome Statute, grants the ICC jurisdiction over four main crimes.
First, the crime of genocide is
characterised by the specific intent to destroy in whole or in part a
national, ethnic, racial or religious group by killing its members or by
other means: causing serious bodily or mental harm to members of the
group; deliberately inflicting on the group conditions of life
calculated to bring about its physical destruction in whole or in part;
imposing measures intended to prevent births within the group; or
forcibly transferring children of the group to another group.
Second, the ICC can prosecute crimes against humanity, which are serious
violations committed as part of a large-scale attack against any
civilian population. The 15 forms of crimes against humanity listed in
the Rome Statute include offences such as murder, rape, imprisonment,
enforced disappearances, enslavement – particularly of women and
children, sexual slavery, torture, apartheid and deportation.
Third, war crimes which are grave breaches of the Geneva conventions in
the context of armed conflict and include, for instance, the use of
child soldiers; the killing or torture of persons such as civilians or
prisoners of war; intentionally directing attacks against hospitals,
historic monuments, or buildings dedicated to religion, education, art,
science or charitable purposes.
Finally, the fourth crime falling within the ICC's jurisdiction is the crime of aggression.
It is the use of armed force by a State against the sovereignty,
integrity or independence of another State. The definition of this crime
was adopted through amending the Rome Statute at the first Review
Conference of the Statute in Kampala, Uganda, in 2010.
On
15 December 2017, the Assembly of States Parties adopted by consensus a
resolution on the activation of the jurisdiction of the Court over the
crime of aggression as of 17 July 2018.
