Practice Relating to Rule 102. Individual Criminal Responsibility
In 2011, in its report to the Human Rights Council, Somalia stated:
Somalia has not ratified AP II [1977 Additional Protocol II] and it is therefore not directly applicable to Somalia as a matter of treaty law. The Government is aware that many provisions of AP II represent customary IHL rules and therefore apply to the situation in Somalia. Such provisions include … Article 6 providing the rule on penal prosecutions due to the fact that these norms are reflected in Common Article 3 of the [1949] Geneva Conventions.
