Brazil's Supreme Court has upheld the use of racial quotas by universities, AFP  reported. The case before the Supreme Court concerned the University of Brasilia, which set quotas in 2004 that 20 percent of admissions slots would go to black, mixed-race or indigenous students. More than 70 percent of Brazil's 98 public universities have such quotas, so the case was considered likely to influence admissions practices nationally. The quotas were challenged by a right-wing party that argued that they were counter to principles of equity. But the Supreme Court ruled that the quotas were justified as a means to redress the impact of centuries of slavery in the nation.
