Dred Scott v. Sandford is a highly controversial case that intensifies the national debate over slavery. The case involves Dred Scott, a slave, who was taken from a slave state to a free territory.

Taney disagrees, ruling that African Americans are not citizens and therefore cannot sue in federal court.

Bollinger that the more formulaic approach of the University of Michigan's undergraduate admissions program, which uses a point system that rates students and awards additional points to minorities, has to be modified.
