2 II. PROCEEDINGS BEFORE THE COMMISSION 4. The IACHR registered the claim under No. 96-04, and after undertaking a preliminary examination, on December 20, 2004, sent it to the State for its observations. On February 17, 2005, the State presented its response, which was sent to the petitioners for their observations. On May 4, 2005, the petitioners presented their response, which was sent to the State for its observations. On August 8, 2005, the State requested an extension of time to respond. On November 15, 2005, the State presented its response, which was sent to the petitioners for them to present their observations. 5. On March 22, 2006, the petitioners presented and additional brief, which was sent to the State for its observations. On May 17, 2006, the State pointed out that in a meeting held with the petitioners, they had reached a friendly settlement agreement and sent the proposal signed by both parties. This agreement included a series of measures to resolve the claims raised as well as a time frame for adopting them. On June 20, 2006, the Commission sent this communication to the petitioners and formalized the beginning of the friendly settlement stage, putting itself at the disposal of the parties and requesting that within a time limit of one month they should comment on the said offer. 6. On June 22, 2006, the petitioners requested that the Commission conduct a followup and review on the fulfillment of the agreement. This communication was sent to the State for its observations. On July 20, 2006, the State reiterated its willingness to arrive at a friendly settlement and indicated on May 16, 2006 that it had drafted "an initial document establishing a number of parameters in the search for a friendly settlement between the parties." 7. On October 23, 2006, Olimpíades Gonzáles made it clear that the State had not fulfilled any of the points of the agreement and that the State had shown no willingness in this regard. The Commission was therefore requested to intervene and "bring the matter before the Inter-American Court for a definitive sanction" should the State persist in its failure to comply. It was also made clear that the State had not granted the protection ordered by the Second Control Tribunal, and that he was being threatened and was in a vulnerable condition. This communication was sent to the State for its observations on December 5, 2006. 5 8. On August 28, 2007, the Commission informed the parties that it had concluded its intervention in the friendly settlement proceedings due to the lack of any meaningful response from the State and that it had decided to continue with the petition proceedings. On October 26, 2007, the Commission requested additional information from the petitioners. On March 7, 2008, the petitioners presented their response, which was sent to the State for its observations. 9. On August 22, 2008, the petitioners filed additional information, which was sent to the State together with a reiteration of a previous request for information. On March 25, 2011, the petitioners presented additional information, which was sent to the State for its observations. On May 26, 2011, the State asked for an extension of 10 days in order to present its observations, which was granted by the Commission.
