President Luiz Inácio Lula da Silva’s administration has suffered a record number of legislative defeats, with Congress overturning nearly half of his presidential vetoes, a systemic trend that is driving the Executive branch to rely on the Supreme Federal Court (STF) to settle political disputes. In the first three years of the administration, Congress analyzed 87 presidential vetoes, rejecting 43 of them—a record defeat rate near 49%. This level of institutional tension has directly resulted in the judicialization of politics, where the Executive attempts to suspend or reverse legislation through the courts after failing in the legislature, thereby increasing regulatory uncertainty for investors who track the Brazil stock market and the Real.
