The duty to disclose doctrine provides that people generally are liable for omissions only if they have a duty to disclose the withheld information. The doctrine has been applied in several contexts. For instance, it requires corrective disclosures from those who have made statements that are rendered misleading by subsequent events. It also protects from liability those who come into possession of material information but remain silent, unless they also have disclosure obligations. Those who choose to speak, however, must speak honestly.
