(UN News Centre) – United Nations Secretary-General António Guterres on Monday stressed the importance of all States ratifying the treaty that established the International Criminal Court as the central institution of the global criminal justice system, known as the Rome Statute. “To ensure accountability around the world, it is essential to reach universal ratification of the Rome Statute,” said Mr. Guterres at the opening in New York of the 16th session of the Assembly of States Parties to the treaty, whose adoption in 1998, he said, was “a hopeful, historic moment near the end of a century marked by atrocities and unspeakable inhumanity.”
