Christophe works as an assistant in the loan department of AA Bank. His job is to prepare the contracts used when customers borrow money from the bank. AA Bank requires all loan contracts to be authorised by the Loans Manager, Delilah. Christophe wants to buy a sports car but he is unable to borrow the necessary money because he has failed to repay bank loans previously. He passes a pile of documents to Delilah for authorisation which includes a contract granting Christophe a six-year interest-free loan from AA Bank. Delilah needs to leave work on time to meet her husband for dinner and hurriedly signs all of the documents without checking them properly. At a later date she discovers that she has mistakenly authorised the loan to Christophe. Discuss whether Delilah and AA Bank are legally bound by the loan contract with Christophe
