On 14 November 2005, an impeachment jury formed by the Buenos Aires Legislature suspended Mayor Ibarra for four months, pending an investigation of his performance that could lead to his removal. He accused the opposition of manipulating the families of República Cromañón's victims in order to ruin his career. On 7 March 2006, after four months of deliberations, the impeachment jury voted to remove Ibarra from office. Trial A trial started on 19 August 2008 and lasted a year.

It was deemed that the band was not at fault for the club being given a permit although it lacked basic fire safety measures such as fire extinguishers, working emergency exits and nonflammable walls and ceilings. The defendants were sentenced as follows: Omar Chabán: 20-year prison sentence Raúl Villarreal: 1-year suspended prison sentence Members of Callejeros: Acquitted, then retried in 2011: 11-year prison sentence (reduced to 7 years in 2012) Diego Argañaraz (manager of Callejeros): 18-year prison sentence Fabiana Fiszbin (ex Control secretary): 2-year prison sentence Ana María Fernández (ex Buenos Aires government servant): 2-year prison sentence Subcommissioner Carlos Díaz: 18-year prison sentence Commissioner Miguel Belay: acquitted The band members of Callejeros were absolved in the 2009 trial, but the 2011 appeals court ruled that they shared responsibility for the fire: witnesses said that the band had encouraged the audience to fire flares.
