In addition to any other penalty provided in this part for any violation of this chapter, the commission, after due consideration of the public interest, may declare void any securities issued, or any assumption of securities made in violation of this chapter. Any such declaration shall not be construed as a bar to the recovery, by an innocent holder-for-value of such securities, of any losses sustained by reason of the wrongful acts of the issuing or assuming public utility.
