WASHINGTON (AP) — The Supreme Court has struck down affirmative action in college admissions, forcing institutions of higher education to look for new ways to achieve diverse student bodies. In a 6-3 decision, the court overturned admissions plans at Harvard and the University of North Carolina, the nation’s oldest private and public colleges, respectively. The two programs violate the Constitution’s equal protection clause, Chief Justice John Roberts wrote for a conservative majority. Justice Sonia Sotomayor wrote in dissent that the decision “rolls back decades of precedent and momentous progress.”
