When does a corporate fiduciary owe a special disclosure duty to a minority stockholder whose stock he purchases? There are several approaches to this question and this decision fully reviews them all. Ultimately the Court adopted the so-called "special circumstances" rule that requires disclosure when the buying fiduciary knows of material facts not known to the seller. Note that in this context what is "material" is a higher bar to pass than in a more common disclosure case.
The decision is also useful for its review of the equitable fraud and common law fraud rules, particularly after a duty to disclose arises because of a past disclosure.
