This edition of the book has every court case a conlaw class will cover other than maybe one or two. I just used this one for a class and had to get the information for one case off of the Internet but other than that everything was in here and I saved a lot of money(the supplement covers up to Sibelius) I am also including the 2012 supplement with this book. There is no reason to buy a newer edition of this textbook, it will cost at least a hundred dollars more and include mainly cases classes will not cover.
