Brazil STF minister lifts secrecy on investigations involving Ciro, Castro, Wagner

Brazilian Supreme Court Minister Mendonça declassified proceedings in investigations nicknamed 'Dark Horse' and those involving politicians Ciro Gomes, Cláudio Castro, and Jaques Wagner, following requests from Justice Fachin and the Prosecutor General's Office. The move increases transparency in politically sensitive probes but does not indicate case outcomes. It matters as it could affect political dynamics ahead of elections.
