New Alliances and Tensions Shake Brazil's Supreme Federal Court Amid Messias Nomination Defeat

Ministers of Brazil's Supreme Federal Court (STF) have identified a strategic alliance between Alexandre de Moraes and Senate President Davi Alcolumbre aimed at blocking the approval of Jorge Messias as a new STF member. The alliance's formation, interpreted by magistrates linked to Messias’s key Senate supporter André Mendonça and other ministers, has introduced fresh intra-court conflicts and may shift institutional power dynamics.

While Moraes did not actively canvass votes against Messias, he signaled his opposition indirectly through intermediaries, including Alcolumbre, with whom he met twice the week before the nomination vote. Observers note Moraes and Alcolumbre shared voting strategies post-sabbatical, with the rejection of Messias reflecting underlying concerns about Messias aligning with a bloc poised to dominate the Court. Moraes’s resistance has been interpreted as an effort to prevent Alcolumbre from leveraging the Court against impeachment requests targeting STF ministers.

This internal dispute is compounded by scrutiny of Moraes and fellow minister Dias Toffoli’s alleged links to ex-banker Daniel Vorcaro, now negotiating a plea deal. Notably, Toffoli sided with Messias’s nomination and expressed disappointment at its failure. Supporters of Messias felt betrayed, revealing fractures within STF alliances. Additionally, heightened tensions between STF minister Gilmar Mendes and senators involved in parliamentary inquiries have worsened Senate-STF relations.

These developments underscore a turbulent chapter within Brazil’s highest court, revealing how judicial and political alliances are deeply intertwined, influencing both appointments and the court’s broader standing within the federal government structure.
