The Supreme Court will soon announce its decisions on two cases that are being called the most important for affirmative action in a quarter century. These cases both challenge the use of racial preferences in the admissions policies at the University of Michigan. On one side of the legal dispute over the Michigan policies are those who argue that creating racial diversity on college campuses is a "compelling interest" that justifies the use of certain types of racial preferences in the admissions process. On the other side are those who argue that any system that rewards people solely on the basis of race is unconstitutional. Who's right? And how will the Supreme Court's decision affect the future of affirmation action?
