In November 2021, he was appointed counsel without portfolio to the prosecutor of the International Criminal Court. His appointment received criticism from civil society actors, for his alleged proximity to President Sebastián Piñera, at a time when the Prosecutor's Office was investigating communications denouncing the commission of crimes against humanity during the 2019 Chilean protests.[2]
