Except as otherwise provided by any law heretofore enacted or by the certificate of incorporation of a bank heretofore organized, the holders of the shares of the capital stock of a bank shall not be liable, by reason of their holding such stock, for any debts, contracts, or obligations of the bank, or for assessments to restore impairments of the capital stock of the bank. In those cases in which any such liability has been imposed upon stockholders by any law heretofore enacted or by any certificate of incorporation heretofore filed, such liability shall terminate one year from the effective date of this act.
