In the case of any determination referred to in paragraph (1), the Secretary may pursue any other appropriate penalties under section 4610 1 of this title.
Sanctions set forth in paragraph (1) may not be imposed under this subsection on a person with respect to acts described in such paragraph or, if such sanctions are in effect against a person on account of such acts, such sanctions shall be terminated, if an MTCR adherent is taking judicial or other enforcement action against that person with respect to such acts, or that person has been found by the government of an MTCR adherent to be innocent of wrongdoing with respect to such acts.
The Secretary, in consultation with the Secretary of State and the Secretary of Defense, may, upon the request of any person, issue an advisory opinion to that person as to whether a proposed activity by that person would subject that person to sanctions under this subsection. Any person who relies in good faith on such an advisory opinion which states that the proposed activity would not subject a person to such sanctions, and any person who thereafter engages in such activity, may not be made subject to such sanctions on account of such activity.
