Butler Brothers Building Company sublet all of the work in a highway construction contract to Ganley Brothers, Inc. Soon thereafter, Ganley brought this action against Butler for fraud in the inducement of the contract. The contract, however, provided: ‘‘The contractor [Ganley] has examined the said contracts ., knows all the requirements, and is not relying upon any statement made by the company in respect thereto.’’ Can Ganley introduce into evidence the oral representations made by Butler?
