Jacob & Youngs, Inc. ("Jacob") was a general contractor that built a country residence for Kent at a cost of about $77,000. Jacob brought suit against Kent to recover an unpaid balance of $3,483.46. Kent learned that some of the
piping, instead of being made by the Reading Iron Company ("Reading Pipe"), was made by the Cohoes Rolling Mill Company ("Cohoes Pipe"), which was contrary to the explicit terms in the contract. Kent demanded that the piping be replaced with Reading Pipe. The pipe replacement, however, meant the demolition of the completed structure at a substantial expense to Jacob. Jacob left the work untouched and asked for a certificate that the final payment was due claiming that the pipes installed were equivalent quality to Reading Pipe. Kent refused to supply the certificate and Jacob subsequently filed suit to recover damages. The trial court ruled in favor of Kent, which was reversed on
appeal, and a new trial was ordered. ==Majority Opinion==
