Sir John W. Salmond, Jurisprudence (1913)
“ No civil wrong is a tort, if it is exclusively the breach of a contract. The law of contracts stands by itself, as a separate department of our legal system, over against the law of torts; and to a large extent liability for breaches of contract and liability for torts are governed by different principles. It may well happen, however, that the same act is both a tort and a breach of contract, and this is so in at least two classes of cases. ”
