If you read my comments, the content is not voided. But it is NOT part of any contract that was breached. A breach is a violation of terms of purchase, either in writing or verbal. A breach is NOT a violation of some unstipulated right at the time of purchase. It is an entirely different issue in contract law.
This is the reason why people purchase title insurance when buying property. Someone can come forward and introduce a new restriction on any purchase. The remedy is not automatically to blame the seller for the problem, even if an objection is lawful. Such an event is NOT a contract breach.
