Mathieson wanted to lease a suite in the new office building owned by Logan, which is the most prestigious one in town. He knew that Logan would not rent to him because of a business deal several years ago that had gone bad, costing Logan a great deal of money. Logan swore he would never do business with Mathieson again. Mathieson paid Muir to act as an agent for his company, and Logan rented to him. Several months later, Logan found out who had really rented the suite. Is this a mistake or misrepresentation - note the type and would the contract be at an end as a result?
