In theory, the Senate can check the Supreme Court by impeaching the judges, the problem is that the Supreme Court checks all the senators and congressmen, by being the only one who can prosecute them.
9 out of 11 Supreme Court judges were indicated by the Labor Party (Lula and Dilma) in the last 20 years, some closely related to Lula. They can do anything they want, without worrying about elections. The president of Brazil doesn't matter anymore, at least for the next couple of presidential elections.
