Lawrence M. Clarke, Inc., was the general contractor for construction of a portion of a sanitary sewer system in Billings, Michigan. Clarke accepted Kim Draeger’s proposal to do the work for a certain price. Draeger arranged with two subcontractors to work on the project. The work pro- vided by Draeger and the subcontractors proved unsatisfactory. All of the work fell under Draeger’s contract with Clarke. Clarke filed a suit in a Michigan state court against Draeger, seeking to recover damages on a theory of quasi contract. The court awarded Clarke $900,000 in damages on that theory. A state intermediate appellate court reversed this award. Why?
