See the Mercosur Treaty, 1991. The Protocol of Brasilia, 1991 (complemented by Decision
17 1998) establishes a rudimentary dispute settlement system for states parties based upon
diplomatic negotiations with arbitration as a last resort. Arbitration was not used until
1999 and the first arbitral award was the Siscomex case: see D. Ventura, ‘First Arbitration
Award in Mercosur – A Community Law in Evolution?’, 14 Leiden Journal of International
Law, 2000, p. 447. See also www.mercosur.int/msweb/.
