No action lies against X unless it can be shown that he induced B to break his contract with A. If B's breach of contract was not due to any wrongful act on the part of X, X is not liable to A.1 If X seeks to recover damages against A, an attorney, for making false representations to B, to induce B to break his contract with X, X must show that B would have performed but for A's false statements.2 If B has no valid contract with A, but only an option which has expired, and the only interference on the part of X is to advise A that such option is not valid, and to buy the property on which such option was given, X has no right of action against A.3 If A, the holder of an option, attempts to sell it to B, and B promises to pay a certain sum to A in case B exercises such option. B can not be compelled to pay such sum of money if he does not exercise such option, but waits until such option has expired and then buys such property from the original owner; and the fact that B tries in vain to prevent the owner from giving an extension of such option, does not increase B's liability.4

If the natural consequence of X's wrongful act is a breach of the contract between A and B, X is liable to A for damages thus caused, although X might not have been able to foresee such result.5 If A's wrongful act is such as naturally to result in a breach of the contract between A and B, X's liability is not impaired by the fact that B's act in terminating such contract was wrongful,6 or that such act was the result of a mistake upon B's part.7 If X holds an assignment of wages which is invalid as against A,8 as where it is not signed by A, but by another man bearing A's name,9 X's act in presenting such assignment to B with knowledge of a mistake in identity and the like, gives to A a right of action against X in case B discharges A.10 The fact that B discharges A without using ordinary care and prudence in ascerno whether A is the person who gave such assignment, does not affect X's liability.11

One who is guilty of interfering with the performance of a contract between two other persons is liable only for the damage which flows naturally and proximately from the breach.12
