116 P.2d 336 | Wash. | 1941
[1] The action is brought upon the doctrine of unjust enrichment, which is recognized and applied in a number of our decisions. Ernst v. Schmidt,
[2] The only error assigned is because of the refusal of the court to admit or consider evidence offered by appellant of damages which he claimed to have sustained because of allegedbreaches of the lease by respondent. In other words, he now seeks to recover for breaches of a lease which this court, at his own instance, held invalid and unenforcible. His position here is utterly inconsistent with the one he took in the former case.
A litigant will not be heard to say in one breath that a contract is of no force or effect, and in the next assert a right to recover upon it. He may not defeat his adversary's cause on the theory that the contract is invalid and, in the same or a subsequent action, claim any rights under it. The agreement cannot be treated as a nullity for one purpose and as a binding contract for another. Williams v. Bemis,
The trial court quite properly refused to admit and consider evidence of any damages arising from respondent's breaches of the lease as such. It did admit *139 and consider evidence of physical damage to the land, alleged to have been occasioned by respondent during his occupancy. While some of the evidence so admitted incidentally tended to establish breaches of the purported lease, it was not admitted or considered for that purpose. Nor was appellant entitled to have it considered for such purpose.
Judgment affirmed.
