No insurer is relieved of its liability upon any bond of a city, county, or state officer because the books and accounts of the principal have been examined and approved as correct by the proper authorities when in fact there has been a breach of the bond of the officer and a loss accruing from this breach. In case of default upon the bond, the city, county, or state authorities have all the remedies against the principal and sureties upon the bonds as are provided by law.
