Facts

The plaintiff was employed to investigate mining claims in the Yukon that were subject to an option. While doing so, he found additional claims that he believed were essential to the profitable operation of the optioned claims, and he and Perry acquired an interest in those additional claims together. The plaintiff had agreed with his employer not to become interested in similar business and had also agreed that contract terms could not be waived or modified except in writing, but the trial court and Appellate Division found that the employer's president and general manager knew of and consented to the plaintiff's investment, though no written consent existed. The plaintiff had reserved the right to withdraw from the investment and have his payment treated as a loan to Perry if the employer disapproved.

Issue

Whether the plaintiff's rights under the Perry-Treadgold contract could be finally determined in his favor despite his duty to his employer and a contractual requirement that waivers or modifications be in writing. More specifically, whether his interest in the claims would otherwise be held in constructive trust for the employer, and whether oral consent prevented that result.

Rule

If an agent acquires property or profits in a venture intimately related to the subject matter of his employment, and in such circumstances that he may not in good conscience retain the beneficial interest, equity may treat him as a constructive trustee at the principal's election. Transactions are severable when they concern distinct subjects and one transaction's misconduct does not forfeit rights already lawfully accrued in another. A contractual prohibition on oral waiver or modification does not prevent the parties from later acting inconsistently with it, and oral consent is at least sufficient to constitute an election not to impose a constructive trust where the principal knowingly permits the agent to retain the investment while the transaction remains executory.

Lena Ortiz worked for Prairie Summit Minerals, a fictional mining firm based in Denver, and was sent to Nevada to evaluate a group of lithium claims the firm was considering acquiring. While there, she learned that an adjacent parcel, owned separately, was necessary to make extraction from the target claims commercially workable, and she quietly bought that parcel with her own money. After Prairie Summit later decided it needed the parcel, Lena refused to convey it except at a large markup.

If Prairie Summit sues in equity, what is the strongest argument for relief under the governing rule?

Explanation. The majority rule is that when an agent acquires property so closely connected to the matter she was employed to investigate that retention would be against good conscience, equity may treat her as a constructive trustee at the principal’s election. It is no answer that the agent was not bound to risk her own funds; she could stay out, but if she enters the venture, she may not withhold its benefit from the principal. Direct theft of funds is unnecessary.
