"...mere advice, warning or information cannot amount to tortious procurement of breach of contract. Whilst granting arguendi causa that a communication which went no further would, in general, not, in the absence of circumstances giving a particular significance, amount to a threat or intimidation, I am unable to understand why it may not be an inducement. In the ordinary meaning of language it would surely be said that a father who told his daughter that her fiancé had been convicted of indecent exposure, had thereby induced her, with or without justification, by truth or by slander, to break her engagement. A man who writes to his mother-in-law telling her that the central heating in his house has broken down may thereby induce her to cancel an intended visit."
