The international criminal justice system comprises nine international criminal courts and tribunals; six are still operational and three have closed down. On average, they operated for almost nine years apiece and concluded 172 cases in which over 250 judges and 23 chief prosecutors were involved. All in all 745 suspects were indicted, 356 were actually tried and, of these, some 281 defendants were convicted. Currently 34 suspects are on trial and 22 are still at large. The ‘average’ convicted perpetrator is male, aged 40 and a member of a military or paramilitary organisation from Europe, Asia or Africa who is acting on behalf of his government. These are just some of the facts and figures which we present in this article: an overview of the empirical reality of the international criminal justice system which has currently been functioning for just over 65 years.
