In February 2006, the Free Enterprise Fund and Beckstead and Watts, LLP (a small Nevada-based accounting firm) filed a lawsuit in federal court challenging the constitutionality of the PCAOB. According to the lawsuit, the provision of the Sarbanes-Oxley Act establishing the PCAOB violated the "Appointments Clause" of the U.S. Constitution, since PCAOB Board members should be viewed as "officers of the United States" because of the public purposes PCAOB serves, and, as such, must either be appointed by the President of the United States, with the advice and consent of the U.S. Senate, or by the "head" of a "department", whereas PCAOB's board is appointed by the SEC, rather than by the Chairman of the SEC. The lawsuit also challenged the PCAOB as violating the Constitution's separation of powers clause, since the organization has quasi-executive, -legislative and -judicial functions.
