Does anyone know of a national layer?

Edit: Sorry for the delay in clarifying.

I am looking for all courts (district, circuit, municipal, Superior, etc.) depending on the terminology used for the state for the USA.

Based on the answers provided and research I've done I don't believe this is available.

I very much appreciate all the feedback and leads.

1 and merge a few state files together from – Mapperz Nov 16 '10 at 3:08
best I could find was state by state – Brad Nesom Nov 16 '10 at 4:18
Either you answered your own question or your not properly describing what you want. Mapperz link to the pacer website provides a map of the appellate circuit courts (which would be considered a federal venue but cases within the states jurisdiction can be appealed to said federal venues.) If that is what you want there is no point in looking for a pre-made layer, as circuits are just several states concatenated together. – Andy W Nov 16 '10 at 4:37
I have downvoted your question, as currently it is unanswerable. The two answers are legitimate, but it is not clear if that is what you are looking for. While most courts (either State or Federal, trial or appellate) will be organized by political boundaries like states or counties, appellate divisions of State court systems are not synonymous across State boundaries (e.g. New Yorks appellate system is different than Vermont's appellate system). Hence if it is a State jurisdictional appellate court no layer for all of the US could exist unless someone made subjective classifications. – Andy W Nov 17 '10 at 20:06

Just a few clicks deeper I found this... text files will work and here is the shape file judicial_districts.shp

Do you mean state district courts, like these?

If so, it seems like many of them use county boundaries, so it'd be something you could create from a national county layer if necessary.
