ABC Ltd$.$ and $123$ Corp. enter a contract for the delivery of molasses from Indonesia to Vancouver. While in transport on a cargo ship, ABC sold its interest to Vancouver Sugar Co$.,$ but while on the way, the seal on the ship broken and sea water had filled the hold of the ship. The molasses is ruined. The cargo ship stopped in Australia to dump out the waste, but no one notified the parties. By the time ABC sold the molasses to Vancouver, it had already been dumped from the cargo ship. Vancouver sues ABC for breach of contract. Is there a common mistake? Why? What is the consequence?
