This article compares and contrasts the interpretation of the Lusaka Ceasefire Agreement 1999 by the International Court of Justice, the Peace Agreement between the Government of Sierra Leone and the Revolutionary United Front of Sierra Leone by the Special Court for Sierra Leone, and the General Framework Agreement for Peace in Bosnia and Herzegovina by the European Court of Human Rights. In doing so, it critically analyses the approach of the three different tribunals and attempts to explain the differences identified on the basis of the jurisdictional scope of each tribunal and the substantive law each has been tasked to apply. This comparison is both substantive and procedural. The article then examines the impact of these three tribunals on two specific aspects of the rule of law: legal accountability and legal certainty, both internationally and in the countries under examination. It is argued that, while these tribunals have enhanced legal certainty and accountability on the international level, any contribution they have made to the domestic rule of law has been questionable.
