This from SCOTUS Blog:
“Starting next week, the Court will release on its own website the audiotape recordings of all of the arguments at the end of each argument week. This will be much faster release than under the prior policy, when they were not available for months — unless, as in a few high-profile cases, the Court released them on the same day of argument — a policy now discontinued.”
Starting with the October Term 2010, visitors to the Supreme Court site can download the FREE MP3 files by clicking on the “Oral Arguments” link from the home page and then clicking on the “Argument Audio”. The argument audio will be posted on Fridays after Conference.
More details about this new policy are available in the Supreme Court’s press release.
