It's right here courtesy of a link from the SCOTUS Blog Orders and Opinions page.
The SCOTUS Blog continues to be one of the best sources for keeping track of what's happening at the USSC. The entire case of Ventris v. Kansas can be viewed here on the wiki page. Virtually every document filed with the court is available as is insightful analysis. Access to the information is free.
For years the "gold standard" in keeping up with events at the USSC has been BNA's U.S. Law Week. You have to wonder about the continued viability of that business model in the face of SCOTUS Blog.
