Case brief summary
If someone mostly finishes a building contract but makes a small, honest mistake that does not matter much, courts will not treat that as breaking the whole deal. Instead of forcing the builder to tear everything apart and redo it, the payment owed is reduced by the small difference in value, not the huge cost of fixing it.
Facts
A construction company built a house for a homeowner for about $77,000. The contract specifically required a certain brand of water pipe, but the subcontractor accidentally installed pipe from other manufacturers that was the same quality, look, and cost, in most of the plumbing. The mistake was not noticed until after the house was finished and occupied, and by then the pipe was sealed inside the walls so replacing it would mean tearing apart finished parts of the house.
Procedural history
The builder sued for the final payment. The trial court blocked evidence that the substitute pipe was just as good and ruled for the homeowner. An appeals court reversed and ordered a new trial, so the homeowner appealed further.
Issue
When a builder makes a small, unintentional, unimportant mistake, should they lose all payment, and should damages be based on the huge cost of rebuilding or the small difference in value?
Holding
The court ruled the builder could still get paid because the mistake was minor and unintentional. Damages should be based on the small value difference, not the high cost of tearing out walls to fix it.
Reasoning
Contracts don't fail just because of a tiny, honest mistake. Fairness requires paying for the real loss, not punishing the builder harshly. Since the pipe was essentially equal in value, the fair damages amount was basically nothing.
Opinions
Majority (Cardozo): A small, honest, unintentional slip in following exact specifications does not forfeit payment, and damages should reflect the minor difference in value, not the cost of demolition.
Dissent (McLaughlin): The builder knowingly failed to use the required pipe throughout and offered no proof of replacement cost, so the homeowner was entitled to exactly what he contracted for.
