Today, I took a look at the Free Court Dockets site. To retrieve docket information (with the exception of US Supreme Court information), you have to request an invitation code from the site. (Click here if you would like to go through the process).
I did not request an invitation code, so I looked at one of the "Hot Docket" cases, GERONIMO v. OBAMA - 09cv00303. The first page, the case summary, gives you the standard plantiff and defendant information, as well as info on their attorneys.
The second page gives you docket information along with the date each document was filed/action taken.
You can download/print/save this information. You can also view when the docket was last updated by the site, and also refresh the docket information.
However, if you want to get a motion, for example, the site redirects you to Pacer, at least it does for the case that I looked at. It also warns that you must have a Pacer account and fees may be assessed.
This site is good if you need basic information, or you want to see the docket, but it appears that you will still need to use Pacer (or Westlaw or Lexis if you want to retrieve docket documents through one of those services) if you need to see the actual motion/document.
