Justice Breyer, joined by Justices Stevens, Ginsburg, and Sotomayor, agreed that PCAOB members were inferior officers but would have upheld the removal provision. In his view, removal-power cases require a functional, context-specific inquiry into whether a restriction materially impedes the President's ability to perform constitutional duties, not a mechanical rule that two layers of for-cause protection are necessarily invalid.
The second layer did not meaningfully diminish presidential authority because the SEC retained virtually complete control over the Board's substantive work. The SEC could approve, amend, or abrogate Board rules; review and modify sanctions; direct inspections and investigations; initiate investigations itself; control the Board's budget; assign responsibilities; and relieve the Board of enforcement responsibilities. Given this pervasive supervision, the President's concededly sufficient control over the SEC supplied sufficient practical control over the PCAOB.
Breyer disputed the majority's claim that the second layer necessarily weakens the President. If the President and SEC agree that a member should stay or go, one of the layers is irrelevant; if they disagree, the first layer protecting the SEC already permits the Commission to resist the President. The second layer may sometimes even help the President by preventing the Commission from removing a Board member the President wishes to retain.
Congress had sound reasons to protect Board members from politically motivated removal. The Board adjudicated disciplinary proceedings and performed highly technical accounting work in an area where Congress reasonably sought professional expertise, impartiality, and public confidence after major corporate-accounting failures.
Precedent, in Breyer's view, supported the statute. Humphrey's Executor permitted for-cause protection for independent-agency leaders; Perkins permitted Congress to restrict a department head's removal of inferior officers; and Morrison focused on whether a restriction actually impeded presidential performance. Congress also had not aggrandized its own power by reserving a role in removals, the central concern underlying Myers and many separation-of-powers cases.
The majority's new rule was both unclear and potentially disruptive. It did not define which inferior officers fell within it, while leaving uncertainty about administrative law judges, senior career officials, and other officials with layered employment protections. Breyer warned that regulated parties could use the decision to challenge officers' authority and destabilize large portions of the administrative state.
Finally, Breyer questioned the majority's unexamined assumption that SEC Commissioners themselves enjoyed for-cause protection. The statute creating the SEC contained no express removal restriction, and he maintained that the Court should not infer such a limitation in order to create the second layer necessary to invalidate the PCAOB provision.
