Meinhard v. Salmon

Joint venturers, like partners, owe one another the duty of the finest loyalty while their enterprise continues. Salmon bore an especially demanding duty because he was not merely a coadventurer; he was the venture's exclusive manager. Fiduciary duty requires more than ordinary market honesty: it requires undivided loyalty and the “punctilio of an honor the most sensitive.”

The new lease opportunity came to Salmon because he controlled the Bristol lease, which was the keystone of the larger redevelopment. Although the landlord dealt with Salmon as apparent sole owner, Salmon in fact held and managed the existing lease for a joint venture. That position gave him a preemptive opportunity that he could not quietly appropriate for himself.

The decisive wrong was Salmon's secrecy. He did not have to guarantee that Meinhard would receive the new lease, but he had to disclose the opportunity and give Meinhard a chance to compete, participate, or seek an alternative arrangement. By keeping the negotiations to himself, Salmon excluded Meinhard from every possible way of benefiting from an opportunity generated by their common enterprise.

Equity would not speculate that Meinhard's chance of success was slight because Salmon was the more experienced real-estate operator. Meinhard might have offered better terms, joined with other capital, or persuaded the landlord to make another arrangement. Salmon's concealment eliminated those possibilities, and a fiduciary may not defend self-dealing by arguing that the excluded beneficiary probably would not have succeeded.

The new transaction was not an ordinary renewal in form, because it covered additional parcels and imposed far greater obligations. But fiduciary loyalty is not confined to rigid categories of transactions. The new lease extended and enlarged the subject matter of the old venture, and Salmon acquired it through an opportunity incident to his managerial position. That close nexus made the opportunity subject to the venture's fiduciary duties.

The new lease was a single, integrated transaction covering the Bristol site and adjoining parcels. A physical or economic division that assigned Meinhard rights only in the former Bristol portion would be artificial and impracticable, particularly because the planned building would cover the entire tract and the lease obligations were indivisible.

Meinhard therefore had to take the benefit and burdens of the new lease as a whole. Since he sought an equitable interest in the transaction, he could not claim only a partial interest while assuming liabilities less extensive than Salmon's. The trustee who combined the Bristol parcel with the adjacent property had to bear the resulting inconvenience of treating the lease as an integrated asset.

The constructive trust could attach either to the lease itself or, at Salmon's option, to shares of Midpoint Realty Company. To respect the original agreement giving Salmon management authority, the Court permitted Salmon to retain one share more than half of the corporate stock, while Meinhard received the balance. This preserved Salmon's expected control without diminishing Meinhard's substantive entitlement to half the venture opportunity.

Meinhard assigned his interest to his wife in 1917, and Salmon thereafter sent the venture's payments directly to her. But neither party treated the assignment as a termination of the venture, and neither acted as though Meinhard had been relieved of his continuing obligation to contribute to expenses if necessary.

The arrangement was understood as a tax-related transfer of income, not as a winding up of the enterprise. Salmon's own conduct over the following years supported the factual conclusion that the joint venture remained active, with its mutual rights and duties intact.

The Court treated the later Partnership Law provision as accurately reflecting the intended effect of the assignment: an assignee may receive the assigning partner's profits, but the assignment alone does not dissolve the enterprise or alter its management. Salmon could not, after years of accepting the venture's continued operation, invoke the assignment only when doing so would avoid his fiduciary obligations.
