Ne Bis in Idem - Rome Statute and Ad Hoc UN Tribunals

Rome Statute and Ad Hoc UN Tribunals

The Rome Statute establishing the International Criminal Court (ICC) states that the ne bis in idem principle has a peculiar meaning, especially if compared to European supranational law. The ICC jurisdiction is complementary to national law, and article 20 of the Rome Statute clearly specifies that, even if the principle shall subsist in general terms, this cannot be taken in consideration in case one of the two conditions (unwillingness and incapability) of existence of the supranational court's jurisdiction occurs. Article 10 of ICTY Statute and article 9 of ICTR Statute state that the non bis in idem principle can be enforced mainly to clarify that the ad hoc tribunal's sentences are "stronger" than the ones in domestic courts. In other words, national courts cannot proceed against the responsible parties of crimes falling in the tribunal's jurisdiction if the international tribunal has already pronounced sentence for the same crimes. However, ICTY and ICTR can judge alleged criminals already sentenced by national courts if:

• the sentence defined the crimes as "ordinary", and
• the judiciary of the state is not considered impartial, the domestic trial is considered a pretense to protect the accused from the legal action of international justice, or the domestic trial is considered as not fair on some fundamental legal basis.
