Fachin separates STF cases and keeps court sessions on different dates
Published · Updated
What happened
On September 12, STF Justice Edson Fachin rejected a request to join the Moraes-related case with the case involving Justice André Mendonça and scheduled the Mendonça matter for a separate session, while preserving the extraordinary session dedicated to the Vorcaro-Moraes file.
Why it matters
By splitting the proceedings, the STF created multiple near-term decision points instead of one consolidated ruling. That increases uncertainty around the court's internal handling of the dispute and lengthens the window for political actors to mobilize around each session.
STF Justice Edson Fachin denied a request to merge the case involving Alexandre de Moraes with the case involving André Mendonça and maintained separate court tracks. He kept the extraordinary session focused on the Vorcaro-Moraes file and set a later plenary session for the Mendonça matter. The immediate effect is to leave the court dispute open across more than one ruling window, extending the period in which Congress and the Planalto may face pressure to take sides or contain spillovers.
