Courtesy of the Constitutional Law Blog, Justice Ginsburg and Justice Scalia tussle operatically in footnotes in Minnesota v. Carter, 525 U.S. 83 (1998). Since both Justices are fans of that wonderful art, we knew such erudite footnotes were coming.
More on law and opera here from Daniel F. Tritter (by way of the Law and the Humanities Institute and the Opera Quarterly), here from Arkansas Online (a court clerk by day and an opera singer by night, and probably by day also); diva Renee Fleming (or at least her voice) guests on Law & Order: SVU (“Bully”), aired March 30, 2011.
