Russia’s veto in the Security Council of a proposed ad hoc tribunal for the Malaysia Airlines Flight MH17 disaster prompts consideration of alternative mechanisms to bring the offenders to justice. It is arguable that the General Assembly, drawing upon the text of the UN Charter and the Uniting for Peace mechanism, possesses the constitutional powers to establish the tribunal. The unique features of the General Assembly, comprising the international community, also mean that it is able to act in a way that would facilitate the functioning of an ad hoc tribunal, even in the absence of mandatory powers. Although many practical obstacles lie ahead, an ad hoc tribunal established by a broad coalition in the General Assembly may offer the best hope in securing accountability for the MH17 disaster.
