The Oyez Project, at www.oyez.org, has made it possible for anyone to listen to the oral argument in most U.S. Supreme Court cases of the past sixty years. Go to that web page. Choose “cases”. Then choose the decade the case was argued. Then choose the year it was argued. Then find the cases for that year, which are listed in alphabetical order. When one finds the case, one clicks on “oral argument” and then on “Download MP3.”
I just listened to the hour-long argument in Storer v Brown, a very important ballot access case argued in 1973. This resource is very useful for any historian or analyst of U.S. Supreme Court behavior. Although transcripts of these old oral arguments have long been available, listening to the argument is far more useful. The old transcripts don’t identify which justice said which statement, but veterans of the U.S. Supreme Court can know which justice spoke if they recognize that justice’s voice. Thanks to HowAppealing for the news about this resource.
