How ironic Utopian, I also work for the U.S. Courts as a Bankruptcy SM!
I've never bothered to research any Witness material as far as court cases on PACER. I'll take a moment on my lunch break to check the national case party index.
For the rest of you, Utopian is right about his pulling case information and posting it here. It would be misuse of his position.
Incidentally, you may not be able to find many cases at the Federal courthouse you visit, because it will only contain information for the district you reside in. The other alternative, if you want to spend a few $$, would be to get a PACER account by contacting them at 1-800-676-6856. There is no charge to obtain a login/password, however the data you query costs you 7 cents per page (appx. 60 lines of text on the screen). Its not much if you are really interested.
Tell them you want to have your account work on the National Case Party Index, as well as for all of the districts of New York, Pennsylvania and perhaps other districts you are interested in.
If you find a case on the National Case Party Index you want to get more details on (such as to view any images of actual documents), you will need to call that 800 number again and tell them to activate your account for that district.
