Practice Relating to Rule 161. International Cooperation in Criminal Proceedings
Colombia’s Criminal Procedure Code (2004) states: “Extradition may be requested, conceded or offered in accordance with the public treaties and, failing this, with the law.”
In 2009, in the Constitutional Case No. C-240/09, the Plenary Chamber of Colombia’s Constitutional Court was called upon to decide on the constitutionality of article 14 of the Law on Judicial Cooperation (1997) and article 162 of the Penal Code (2000), which concern the recruitment of children and their forced participation in hostilities. The Court stated:
4.2.3. … [I]t can be concluded that in accordance with the 1949 Geneva Conventions and their  Additional Protocols ratified by Colombia, the recruitment of children below 15 years of age and their participation in armed conflict is a conduct prohibited by IHL.
The States Parties, in light of the above, assume the commitment to take all legislative measures as necessary to punish those persons responsible for grave breaches of these Conventions. Additionally, States have the obligation to prosecute those persons suspected of committing grave breaches of these treaties or to transfer them to be prosecuted in another State. In other words, the perpetrators of grave breaches – war criminals – must always be prosecuted, and this responsibility falls to the States.
