Vane v. Newcombe was a Supreme Court case that was decided in 1820. The case involved a dispute between two parties over a contract for the sale of a ship. The plaintiff, Vane, had entered into a contract with the defendant, Newcombe, to purchase a ship for a certain sum of money. Vane had paid the agreed-upon sum, but Newcombe had failed to deliver the ship. Vane then sued Newcombe for breach of contract. The Supreme Court held that Newcombe was liable for breach of contract. The Court found that the contract between the parties was valid and enforceable, and that Newcombe had failed to fulfill his obligations under the contract. The Court also held that Vane was entitled to damages for the breach of contract. The decision in Vane v. Newcombe established the principle that a party who breaches a contract is liable for damages. This case is still cited today as an example of the importance of upholding contracts and the consequences of breaching them.

In Vane v. Newcombe, the Supreme Court of Canada held that a contract between two parties was valid and enforceable even though it had not been signed by both parties. The majority opinion found that there was sufficient evidence to prove that the agreement had been made in good faith and with consideration given from both sides. However, Justice Ritchie dissented on this point, arguing that without a signature from each party, there could be no certainty as to whether or not they were bound by its terms. He argued further that such an arrangement would lead to uncertainty in contractual relationships and should therefore be avoided whenever possible. In conclusion, he suggested instead relying upon more traditional methods of proving contracts such as written documents or oral testimony which provide greater assurance of their validity than mere circumstantial evidence alone can offer.
