GIS Layer of USA State Court Jurisdiction Boundaries

In the answer with the most votes, the link to judicial_districts.shp does not work. Also, it seemed to point to OneDrive, leaving the provenance unclear.

I've found a shapefile of the 94 US District Court jurisdictions on the "Homeland Infrastructure Foundation-Level Data (HIFLD)" site.

I haven't found a GIS map of the Federal circuits, but there's an image of one on the United States courts of appeals Wikipedia page, as well as a text listing of the districts which each circuit comprises (It seems as though all districts in any state are in the same circuit, so it would be easier to have a list of states, but I haven't seen a list in that format.)

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.
