El libro negro de la justicia chilena
During her journalistic work in the judicial field, she gathered information for a book chronicling the branch's performance. The book included information such as the behavior of judges during the dictatorship of Augusto Pinochet and the crimes that some committed for being members of the Supreme Court, which put them in a position of abuse of power in certain circumstances. The publishing house that would distribute the book took the risk in publishing the work. One day before its launch, Minister Servando Jordán requested to confiscate all copies, accusing the author of violating the State Security Law. Faced with this conflict, the journalist was politically asylumed in the United States. Meanwhile, legal actions were carried out that would end with the drafting of a law that would protect journalists and their sources. In 2016, Matus re-released the book in a new, corrected, and expanded version. ==References==
