BUCKLEY v. VALEO 1 Per Curiam withstanding any other provision of law, any person with respect to whom an advisory opinion is rendered ...who acts in good faith in accordance with the provisions and findings [thereof] shall be presumed to be in compliance with the [statutory provision] with respect to which such advisory opinion is rendered." § 437f (b). In the course of administering the provisions for Presidential campaign financing, the Commission may authorize convention expenditures which exceed the statutory limits. 26 U. S.

If after the Commission's post-disbursement audit of candidates receiving payments under Chapter 95 or 96 it finds an overpayment, it is empowered to seek repayment of all funds due the Secretary of the Treasury. 26 U.

In no respect do the foregoing civil actions require the concurrence of or participation by the Attorney General; conversely, the decision not to seek judicial relief in the above respects would appear to rest solely with the Commission.1 5 3 With respect to the 153 This conclusion seems to follow from the manner in which the subsections of § 437g interrelate. Any person may file, and the
