Argonaut Great Central Insurance Co. v. Mitchell

Mitchell, a garbage collector who regularly hopped on and off the back of his county's garbage truck, was killed when the truck was rear-ended, pinning him against it, with disputed evidence about his exact position at the moment of impact; Argonaut (plaintiff), the county's insurer covering anyone occupying an insured vehicle, sued Mitchell's estate (defendant) seeking a declaration that he wasn't covered, and the district court granted summary judgment to the estate.
