counsel not only the Gualeguaychú Assembly, but also Entre Ríos governor Busti. The CEDHA, now presided by Picolotti's husband Daniel Taillant, provided legal advice to the Argentine case at the ICJ, and later organized a tour of several countries to raise international awareness of the pulp mills and present arguments against their construction. The case at the ICJ Argentina sued Uruguay in the International Court of Justice, arguing that it had breached a treaty obligation to consult before doing anything that might affect the river. However, in July the court rejected its request for an injunction to stop construction of the mills. Uruguay took its case to Mercosur, arguing that Argentina had failed to take action to ensure the free circulation of goods and services. During their defense at the ICJ, the Uruguayan authorities pointed to the fact that the mills were to use a technology known as Elemental Chlorine-Free (or ECF) bleaching (employing chlorine dioxide), which has been adopted by both the United States and the European Union as the "best available technology" in their wood pulp processing environmental regulations, and that an independent World Bank study has supported their position. As to the alleged violation of the Treaty of the Uruguay River, Uruguay's legal defense team asserted that discussions over the building of the mills were conducted, and that Argentine officials offered no objections. After two months of calm while the International Court of Justice in The Hague studied the Argentine accusation, the conflict was re-ignited on 13 July, when the ICJ ruled that Argentina had not convinced the court that Uruguay's actions at present were enough to grant a provisional measure halting the construction of the two pulp mills. This judgment did not settle the question of whether Uruguay is ultimately breaching its Treaty obligations to Argentina, but ruled that no imminent danger of irreparable damage exists at the moment, and that Uruguay may still be liable to Argentina if it is later found in the final judgment that Uruguay is indeed in breach of Treaty obligations. Judges at the ICJ voted 14–1 in Uruguay's favour (the only vote against Uruguay was cast by the judge appointed by Argentina). The next day, the Gualeguaychú Assembly organized a protest demonstration, with cars, bicycles and people on foot marching along National Route 14 and finally gathering in the city. According to Assembly leaders, new road blockades will be avoided,
