A split decision from the Supreme Court on affirmative action at colleges. The court is letting colleges give minority applicants an edge when applying. But it's also saying that race can't be too much of a factor when college officials pick students. The court has ruled in two cases, both involving the University of Michigan. The justices ruled in favor of an affirmative action program at the university's law school. The court says the program, which gives minority applicants an edge, isn't an illegal quota. But in a second ruling, the court struck down another University of Michigan affirmative action policy, one that's more preferential toward minority applicants than the law school policy. The rulings preserve the idea that racial preferences can be used to give minorities more of a presence on college campuses. But they also say such preferences must be used sparingly.
