Template:Warrantydescription
A warranty is a statement of a present or historical fact made as a term of a contract. If a warrantor breaches its warranty the injured party might claim damages for the breach of contract and sue for damages, but cannot rescind it altogether. To set aside the contract as if it never happened — to void it, ab initio — you would need to prove a misrepresentation from someone before the contract, that induced you to enter it.
As a creature of contract, liability for the failure of a warranty to be correct is absolute: it is no defence that one could not reasonably have known that the matters warranted were not true, or that some mendacious interloper (other than the other party to the contract) has intervened to defeat the warrantor’s best intentions unless that kind of conditionality is written into the contract. This is the appeal of a written contract: the parties can write down with infinite, tedious precision, what they mean to say, and what they say they mean.
It also points up the logical befuddlement behind the idea of writing representations into a contract.
