You can use Westlaw for Appellate court decisions that will tell you where case originated, and you can search Judaical districts for cost and access on earlier record of case.. Google to Minnesota Courts. Older records access is time consuming and very expensive. In Hennepin County some records on microfilm, and some stuff in salt cave far away. Searching old indexes is a real pain- mistakes, book are very heavy, etc. Happy Historical Trails, Robert P. Mosedale Bloodhound Research, P. A. rmosedale@juno.com
