13. Fiduciary duty

Dennis Ranzau and William Brosseau formed a partnership to purchase the Casa T, a house in Acapulco. Their intent was to use the Casa T as a vacation home for a few weeks each year, to lease it for the remainder of each year, and to share the rental income after expenses. Ranzau soon became concerned that Brosseau was not accounting for the expenses and income of the Casa T. Brosseau refused Ranzaus requests to provide receipts for expenses Brosseau claimed to have incurred on the house. Brosseau also let his friend have total run of the house over Ranzaus objection. On another occasion, Ranzaus wife and her friends were locked out of the house by an agent of Brosseau and had to make other accommodation arrangements. Has Brosseau breached his fiduciary duty to Ranzau?
