The instruments were presented by H.E. Ms. Edita Hrdá, Permanent Representative of the Czech Republic to the United Nations, at a ceremony attended by H.E. Mr. Sidiki Kaba, President of the Assembly of States Parties to the Rome Statute, and Mr. Stefan Barriga, Deputy Permanent Representative of Liechtenstein to the United Nations.

The first Review Conference of the Rome Statute, held in 2010 in Kampala, Uganda, adopted a set of amendments to Article 8 which defined as war crimes the use of certain weapons during armed conflicts not of an international character. The conference also adopted a definition of the crime of aggression and the provisions for the exercise of Court´s jurisdiction. The Court may exercise jurisdiction over the crime of aggression on January 1, 2017, once thirty States Parties have ratified the amendment, and subject to a subsequent decision by the Assembly of States Parties.

The Czech Republic supports the role of the International Criminal Court and has participated actively in the negotiations on the definition of the crime of aggression. Since 2012, Mr. Robert Fremr has been a judge at the ICC and serves as the president of the Trial Division. The support of the international criminal justice is closely linked with the rule of law, respect to human rights and international humanitarian law.

On March 12, 2015, the Czech Republic also deposited the instrument of ratification of the UN Convention on Jurisdictional Immunities of States and Their Property. The Convention was signed on December 2, 2004 in New York and will enter into force once thirty States have ratified it. The Czech Republic has become the 17th state to deposit the instrument of ratification of the Convention.
