What the Investigation Involves

An administrative summary is an internal inquiry aimed at determining potential administrative responsibilities. It does not imply punishment or constitute a criminal presumption. At this stage, the Court can appoint an investigating attorney, gather evidence, and take statements in accordance with current regulations.

‘Belarusian Doll’

The investigation is part of the case known as “Belarusian Doll”, concerning alleged bribery and money laundering, which has led to searches and seizures of computers and phones, in addition to the arrest of accountant Gonzalo Migueles —husband of former Supreme Court Minister Ángela Vivanco— along with attorney Eduardo Lagos and his partner, attorney Mario Vargas Cociña, all brought before the 7th Guarantee Court of Santiago for formalization. The Court indicated that the summary aims to establish potential administrative responsibilities based on the “serious incidents” reported by the press and internal evidence.

Meanwhile, Ángela Vivanco remains under investigation in the same inquiry; due to her previous privilege as a minister of the highest court, any potential arrest would require a complaint for chapters, a process that is already underway. The case, linked by the press to a network of payments and favors —the “Belarusian Doll”— is the backdrop for the San Miguel court’s decision to open this summary against the Property Registrar of Puente Alto and the notaries of the jurisdiction.

With the investigation ongoing, the appellate court will need to determine if there are administrative faults and, if so, propose disciplinary measures in accordance with legal frameworks. The Court has stated that it will continue to provide official information as the summary investigation progresses.
