Nathan Clifford, Steam-Engine Company v. Hubbard…
“ Where all these things concur, the president is liable, not for all the debts of the corporation, but for all such as were contracted while he was guilty of such default. If he was not the president at the time of the default, or if the debt was contracted before he was in default, then he is not liable, as the case is not brought within the letter or spirit of the statute. Liability in such a case, as imposed, is in its nature penal, and in order to render such an officer responsible it must appear that he has neglected or refused to do some act which the law made it his duty to perform. ”
