A review by a judge on the U.S. Court of Appeals for the Sixth Circuit has found that Chief Judge Boyce Martin improperly intervened in the University of Michigan affirmative action case in a fashion that may have affected the outcome. See news reports here and here. [Note: Some news reports on this matter imply the Sixth Circuit’s decision split on purely partisan lines. This is untrue. One Clinton appointee voted to invalidate the University’s use of preferences in admissions.]
