Here in Los Angeles, we have the Second Circuit Courts of Appeal. Read this. The website is remarkable for what it can do. You can check out cases, including the progression of your case, if you get that far.
You get assigned to the Division supposedly at random, but believe me, you will wish for some and not for others. And download forms, and get a sense of who the justices are (in the COA the judges are justices). And you get lawyers who specialize in appeals cases. I did my own. Huh!
