Wave of ratifications continues as Costa Rica becomes 22nd State Party to Kampala Amendments: On 5 February 2015, the Vice President of Costa Rica, Ms. Ana Helena Chacón Echeverría, deposited her country’s instrument of ratification of the Kampala Amendments. Costa Rica became the 22nd State Party to ratify the amendments overall and the second in as many weeks. The Latin American region played a crucial role in negotiation of the crime of aggression amendments; many States Parties from the region are expected to ratify the amendments in the near future. We remain confident that the threshold of 30 ratifications needed for the activation of the amendments on the crime of aggression will be reached well before the end of 2015.
