Stanley Forman Reed,
Vandenbark v. Owens-Illinois Glass Company…
“ Tompkins [6] made the law of the state, as declared by its highest court, effective to govern tort cases cognizable in federal courts on the sole ground of diversity, there was no necessity there for discussing at what step in the cause the state law would be finally determined. In that case no change occurred in the state decisions between the accident and our judgment. There is nothing in the Rules of Decision section to point the way to a solution. ”
