Relief will be given if the architect issues his certificate under a clear mistake of fact,1 or in clear violation of an express provision of the contract.2 Thus a certificate that a building contract has been performed fully does not bind the owner if a heating apparatus provided for by the contract has not been furnished.3 Equity will give relief if the architect has been guilty of fraud or manifest error.4 If mistake exists, fraud need not also exist to entitle the party to relief.5
