The defense of Senator Miguel Ángel Calisto filed an amparo action before the Coyhaique Court of Appeals to challenge the closure of an investigation into alleged fraud against the state.
The filing seeks to reverse the case closure and obtain additional time to request investigative steps. It was submitted on July 4, 2026, by lawyers César Ramos Pérez and Andrea Lema Abarca.
The probe, opened in 2021, accuses the senator of fraud against the Treasury. Prosecutors seek a 12-year prison sentence. The original investigation deadline was July 9, 2026, yet the Public Ministry closed the case on June 25.
The lawyers question shifts in statements by co-defendants Roland Cárcamo and Carla Graf on April 29, 2026. They note the pair altered their accounts, after which Cárcamo gained release from pretrial detention. They also cite barriers to accessing case files before the closure.
