Whether the transferee court in this multidistrict diversity proceeding had to apply the substantive and choice-of-law rules that the transferor courts would have applied.
Holding
Yes. The court applied the substantive law, including choice-of-law rules, applicable in the transferor forums, while concluding that no pertinent state law would impose liability on these facts.
Reasoning
A federal court receiving cases through multidistrict transfer applies the substantive law that the transferor courts would have applied. Because the cases were based on diversity jurisdiction, that includes each transferor forum state's choice-of-law rules under Klaxon.
The cases involving Scotfoam came from 39 jurisdictions, so differences in state law or in the evidence about a particular implant could in principle produce different results. But after examining the relevant state authorities, the court concluded that the same dispositive principle controlled: a supplier of a nondefective, non-inherently-dangerous raw material does not owe the asserted warning duty to remote users of a specialized finished product.
