There are numerous checks that limit the power of the prosecutor and regulate the ICC's operations.  There are numerous checks outlined in the Rome Statute that limit the power of the prosecutor, eliminating any concerns of abuse. For example, Article 7 clearly defines what a crime against humanity is, and other types of crimes are extensively defined in the statute. Second, the ICC is allowed to step in only if the national government fails to prosecute criminals, meaning that it will never have to step in and exercise its power as long as countries are doing their jobs domestically, checking its jurisdiction. Third, there are multiple chambers that check each other; for example, the pre-trial chamber makes sure that the prosecutor has enough evidence before proceeding. Fourth, there are 18 judges from differing impartial backgrounds, ultimately making the ICC objective. Other checks can be found upon closer examination of the Rome Statute.1 Moreover, empirically, the prosecutor has not excessively punished any leader, so claims of abuse have yet to show true in the real world. Trials have been dismissed on the grounds of not having sufficient evidence, etc., so the ICC does not have unlimited power.  1 United Nations.
