A person commits the tort of procuring a breach of contract if he intentionally causes the other party to a contract to breach it or prevents or hinders the performance of the contract so that the third party (the other contractual party) suffers loss.
Typically this might be a competitor telling your customer to end a contract with you prematurely so that it might get your business.
Any agent (employee or contractor) acting in good faith for their principal with actual/implied or ostensible authority in procuring such a breach would be covered by agency law so ordinarily would not be personally liable so causing the illegal breach. Instead his principal-his employer would “carry the can”.
This was the essence of the High Court decision of Crystalens Limited v White where two technology companies CYS and CRL had entered into a collaboration agreement that had later foundered and CYS later claimed against the managing director of CRL personally for CRL’s decision not to do any more work for CYS since CRL by the time the action began had gone into administration.
The MD was successful in striking out the claim for the following reasons:
The element of good faith was an important element of the defence of the MD here and directors should understand the importance of this legally and be able to put this into practice on a daily basis.
