While the Statute of the International Criminal Court guarantees to suspects and accused the right to be defended in person or through legal assistance, it contains little guidance as to the extent to which this most fundamental right will be provided. In order to ascertain how broadly it should be applied, the authors examine the application of the right by the ad hoc international criminal tribunals for Rwanda and the former Yugoslavia. The authors note that the defence-orientated approach taken by the ad hoc Tribunals to the right to be defended in person or through legal assistance not only conforms with international obligations, but also in many respects goes beyond that required by international human rights law. It is, therefore, crucial that the ICC listens to the experience of the ad hoc Tribunals and adopts similar, if not identical, rules and regulations relating to the qualifications, conduct and assignment of counsel.
