SCOTUSBlog: “Editor’s note:  During the Supreme Court’s summer recess, the blog is publishing a series of posts that explain, in non-legal terms, some of the most important cases that the Court will consider in the new Term that starts October 1.  This is another in that series.  It explains the cases of Nix v. Holder and Shelby County v. Holder.   Beginning next Monday, the blog will be hosting a symposium on the controversy over the law involved in those cases: the Voting Rights Act of 1965.“
