Following the president's decision  last year to exploit the oil fields in Parque Nacional Yasuní  [en] [Yasuní National Park] an oppositional movement  began and became quickly organized . It started carrying out marches  for collecting signatures  in order to hold a popular consultation regarding Yasuni's fate.
On Saturday, April 12th the Yasunidos  collective, along with other organizations, presented  almost 750,000 signatures before the CNE  [National Electoral Board, for its Spanish name] so that it may be passed on to the Consulta Popular del Yasuní ITT [The Yasuní ITT Popular Consultation]. The CNE accounted  for receiving the signatures and indicates that the minimum signatures required were 583,324. It also announced  that the signature verification procedure started on Monday, April 14th.
However, on Thursday, April 17th an incident  occurred involving Yasunidos members. They blocked the boxes, containing the forms of the collected signatures, from being transferred between the CNE and the signature verification center. They claimed there were irregularities  in the procedure.

They want to take the boxes away without our consent despite the petition to postpone the procedure until we're certain.
On Friday, April 18th the CNE announced that the procedure is advancing  in accordance to the established timetable and that the presence of supervisors  guarantees its transparency and proper conduct. Nevertheless, activists continue to denounce irregularities with the procedure.
