Continuing Cohen, Varat, and Amar's excellent treatment of this area of law, the Concise Twelfth Edition provides an overview and focuses closely on Supreme Court decisions. The concise casebook cites key cases in its discussions of the Court's re-emphasis on federalism disputes, racial gerrymandering, sex discrimination material, and changes in first amendment standards. As with the full coverage edition, this concise casebook contains the raw materials (cases, constitutional provisions, statutes, and historical documents) to give teachers maximum freedom to pursue their own teaching strategies. It contains discussions of cases decided during the October 2003 term, including such recent controversies as the impeachment of President Clinton and Bush v. Gore as well as cases handed down up until the fall of 2005.
