by John Marshall Harlan, Ralston v. Turpin — Opinion of the Court
“ In accepting a gift from his principal, he is under an obligation to withhold no information in his possession respecting the subject of the gift, or the condition of the estate in his hands, which good faith requires to be disclosed, or that may reasonably influence the judgment of the principal in making the gift. All transactions between them whereby the agent derives advantages beyond legitimate compensation for his services will be closely examined by courts of equity, and set aside if there be any ground to suppose that he has abused the confidence reposed in him. ”
