Harry Blackmun,
Salve Regina College v. Russell…
“ In a case where the controlling question of state law remains unsettled, it is not unreasonable to assume that the considered judgment of the court of appeals frequently will coincide with the reasoned determination of the district court. Where the state-law determinations of the two courts diverge, the choice between these standards of review is of no significance if the appellate court concludes that the district court was clearly wrong. ”
