In January 2008 Arti entered in a contractual agreement with Bee Ltd to write a study manual for an international accountancy body’s award. The manual was to cover the period from September 2008 till June 2009, and it was a term of the contract that the text be supplied by 30 June 2008 so that it could be printed in time for September. By 30 May, Arti had not yet started on the text and indeed he had written to Bee Ltd stating that he was too busy to write the text.Bee Ltd was extremely perturbed by the news, especially as it had acquired the contract to supply all of the accountancy body’s study manuals and had already incurred extensive preliminary expenses in relation to the publication of the new manual.Required:In the context of the law of contract, advise Bee Ltd whether they can take any action against Arti.
