Whether Pennsylvania law governed the disputed contract-performance, anticipatory-breach, and damages questions.
Holding
Yes. Pennsylvania law governed the remaining substantive issues, and it also supplied the applicable apparent-authority rule.
Reasoning
A federal court sitting in diversity applies the forum state's choice-of-law rules. Pennsylvania was the forum, and the relevant conduct by WIOO and Waite concerning Waite's authority occurred there. In any event, Pennsylvania and Tennessee followed materially the same Restatement approach to apparent authority, so the authority issue did not turn on a conflict between the two states' laws.
Pennsylvania was also the place where the contracts were to be performed because WIOO's promised airtime was to be broadcast from its Pennsylvania station. Under Pennsylvania choice-of-law principles, matters connected with contractual performance are governed by the law of the place of performance. Pennsylvania law therefore controlled anticipatory breach and damages.
