In 1929 the English Court of Appeal held an English Contract to smuggle whisky into the United States contrary to the prohibition laws unenforceable. The case was unusual in that the English court took note of illegality under a foreign law. The writer argues that the reasoning behind this case requires disentangling, and that a general principle of non-enforcement of contracts which contemplate the breach of foreign laws in a way contrary to international morality should be developed from it.
