territory), the Confederation of Indigenous Peoples of Bolivia, and the highland indigenous confederation CONAMAQ announced they would participate in a national march opposing the project. This march—the "Eighth Grand National Indigenous March"—travelled from Trinidad, Beni to La Paz in opposition to the project, beginning on August 15, 2011. On September 25, a police raid on the march resulted in the detention of hundreds of marchers, who were later released. The march regrouped and arrived in La Paz on October 19 to a massive public welcome. During the march, other movements such as the Cochabamba campesino confederation and the colonos union in Yucumo mobilized in favor of the project. In early October, the Plurinational Legislative Assembly passed legislation authored by the MAS authorizing the road following a consultation process, but indigenous deputies and the indigenous movement opposed the bill. At the opening of negotiations with the protesters on October 21, Morales announced that he would veto the legislation and support the text proposed by the indigenous deputies. This text was passed by the Assembly and signed into law on October 24, effectively ending the conflict. Law 180 of 2011 declares TIPNIS an intangible zone and prohibits the construction of highways that cross it. Plurinational Encuentro Beginning in early 2011, the Morales government insisted that any new moves on the fuel subsidy issue raised in the gasolinazo would be agreed on by multiple sectors of society in a summit. Following the TIPNIS controversy and various calls from supporters to "re-drive the process of change," the government organized a broader Plurinational Encuentro to Deepen the Process of Change (), charged with setting the government's agenda for 2012. The Encuentro consists of three parts: opening and closing general meetings bracket a period of consultation with the broader membership of participating organizations. The opening encounter united numerous sectoral organizations, the President, Vice President, Cabinet Ministers, legislators, MAS-IPSP governors, and other officials at the Casa Campestre on the west side of the city of Cochabamba on 12–14 December 2011. Some 650 delegates organized themselves into 10 thematic tables which produced an agenda including no fewer than 51 new laws. Indigenous confederations CIDOB and CONAMAQ declined to attend organized an alternate assembly in Santa Cruz. The COB labor Federation also avoided the meeting and met separately to propose a national agenda. The closing meetings were held 9–12 January 2012. 2012 Nationalization of electrical grid On 1 May
