 Barbara Grutter, in a separate proceeding, sued the Law School of the University of Michigan relying on additional data also revealed by Cohen's FOIA inquiry.While the U-M changed its "grid system" to a "point system" the following year, it argued that both mechanical systems were identical in outcome and that the point system, which became more famous, was designed merely to be easier to understand.The system that Cohen made public was ruled unconstitutional by the U. S. Supreme Court [in Gratz v. Bollinger, 2003] as a "mechanical system," although in a separate ruling concerning the U-M Law School [Grutter v. Bollinger, 2003], the limited use of non-mechanical preferences was allowed.
