Ken jones, the number-one-ranked prizefighter in his weight class, signed a two-year contract with howard stayword. the contract obligated stayword to represent and promote jones in all business and professional matters, including the arrangement of fights. for these services, jones was to pay stayword 10 percent of gross earnings. after a year, when stayword proved unsuccessful in arranging a title match with the champion, jones fired stayword. during the following year, jones earned $4 million. stayword sued jones for $400,000. jones defended himself on the basis that a principal has the absolute power at any time to terminate an agency relationship by discharging the agent, so he was not liable to stayword. was jones correct?
