Numbers: There are two (so far as I know) US *District* Court decisions which (sfIk) were not appealed. One in WashDC and one in Oklahoma.
You might try emailing the NRA and also sofmag.com to see if they have more info. I know SOF referenced it, or James Pate did in one of his articles for them.
Also, the US Supreme Court has all its cases on a website. I don't have it bookmarked on this computer, but I found it via a Yahoo search. It'll be a dot-gov site...
Hope this helps, Art
