Whether an owner whose contractor deliberately fails to perform a land-improvement covenant may recover the reasonable cost of completion rather than the diminution in the land's market value.
Holding
Yes. The ordinary measure is the reasonable cost of completing the promised performance, not the difference in market value, where the contractor has willfully failed to perform and completion would not cause economic waste.
Reasoning
Contract damages aim, so far as money can do so, to give the injured promisee what the contract promised. Here, what Groves purchased was not merely an increment in the land's market price. It purchased a physical result: a tract graded to the agreed uniform level. The appropriate compensation is therefore the reasonable cost of obtaining that promised result.
Wunder's breach was deliberate, not a good-faith or minor deviation from an otherwise substantially performed contract. Minnesota law denies a willful contractor the equitable benefit of substantial performance. Allowing Wunder to limit damages because the completed work would add little market value would reward its intentional refusal to do work for which it had already been paid.
The land's limited present value did not diminish Groves's contractual right to improve it. An owner may choose to make an improvement that is unprofitable, aesthetically undesirable, or intended for future development. A contractor who agreed to perform and received payment cannot defend its breach by arguing that performance would not have benefited the owner in market-value terms.
The court distinguished tort rules, under which damage to real property is often measured by diminished value. In this contract action, the loss was not simply damage to land; it was the deprivation of promised and paid-for construction work. Measuring recovery by current land value would improperly substitute a tort measure for the contract measure.
