Worried about the judiciary's tendency to invalidate pro-labor laws, allies of Perón in Congress decided to impeach three justices for alleged misconduct. A fourth justice chose to resign prior to the impeachment proceedings. This move was part of Perón's strategy to secure control over the Supreme Court.
Following the impeachment, Perón appointed four loyal justices who aligned with his views. With this new composition, the court ceased to challenge his authority, allowing Perón to enact his policies without legal obstruction.
