Media Trial 
Held three media leaders accountable for inciting genocide while preserving important protections of international law on the right to freedom of expression, citing as an example, an interview of Barayagwiza broadcast on RTLM, which it described as “a moving personal account of his experience of discrimination as a Hutu”. The judgement held that it was “critical to distinguish between the discussion of ethnic consciousness and the promotion of ethnic hatred” and that the broadcast by Barayagwiza fell squarely within the scope of speech that is protected by the right to freedom of expression. Bagilishema Trial 
Acquitted Ignace Bagilishema, the former Bourgmestre (mayor) of Mabanza Commune, because the prosecution failed to prove its case beyond reasonable doubt. This helped demonstrate the impartiality of the tribunal. In his separate opinion acquitting the accused, Justice Gunawardana considered Bagilishema’s plea that he lacked the means and resources to prevent the alleged commission of the atrocities in Mabanza Commune, and that he maintained law and order, to the best of his ability, with the resources that were available to him.
