Answer: In Ellen's favor
Step-by-step explanation:
A component of the contract between Ellen and Grapes & Vines was breached which was that the wine was to be delivered "on or before May 1''. It was delivered on the 2nd which was a breach of contract which means that the contract can be voided.
If Grapes and Vines uses the defense that their van broke down and therefore it is a care of extraordinary circumstances, all efforts should have been made to contact Ellen to explain this situation. This was not done so Ellen was within her right to cancel the contract.
