District Court is where you start if you have case that belongs or is in the jurisdiction of the Feder Court System.

I think you have situations like the Remand in Collins where the 5th Circuit Court of Appeals sent the case down to the Southern District Court of Texas. Appellate Courts generally do not decide issues of fact but focus on whether the correct law was applied to the facts or if the parties were treated correctly under the law

Some cases belong in State court system - ie where the issue is local and the parties are residents of the same State. Most cases are probably litigated in State courts
