There are nine justices on the Supreme Court, and, unlike any other job in our government, Supreme Court justices are appointed for life, or for as long as they want to stay.
Há nove juízes no Supremo Tribunal, e, ao contrário de qualquer  outro trabalho no governo, os juízes do Supremo Tribunal  têm cargos vitalícios, ou pelo tempo que o queiram exercer.
