Discuss the below in detail:
Q: Stephen Jones, Daniel Fern, and three others were partners in a law firm. Kansallis Finance, Ltd., obtained an opinion letter from Jones issued on the law firm's letterhead. It contained several intentional misrepresentations concerning a proposed transaction and was part of a conspiracy by Jones and others (but not any of his law partners) to defraud Kansallis. Jones was convicted of fraud, but Kansallis was unable to recover its loss from Jones or the other conspirators. Kansallis sued Jones's law partners, alleging Jones had authority to issue the letter, thus they were liable for the damage caused by it when issued on the partnership letterhead and within the scope of its business. How should the court rule on the liability of Jones's partners?
