The Independent Review Board ("IRB") is a three-member panel established by the Consent Decree to investigate and take appropriate action with respect to "any allegations of corruption," "any allegations of domination or control or influence" of any part of the Union by organized crime, and any failure to cooperate fully with the IRB.

The IRB operates under rules approved by the United States District Court in 1992. The IRB consists of three members, one designated by the Attorney General of the United States on behalf of the Government, one designated by the IBT, and a third member chosen by the Government and Union designees.

The initial members of the IRB served until the 1996 Convention when they were each renominated and confirmed by the Court to serve five-year terms lasting until the 2001 Convention. The Union and the Government designated new members following the 2001 Convention. The Government designated former Attorney General Benjamin R. Civiletti (now a partner in the firm of Venable, Baetjer, Howard & Civiletti). The Union designated former United States Attorney for the District of Columbia Joseph E. diGenova (now a principal at the firm of diGenova & Toensing). In accord with the Rules approved by the Court, Mr. Civiletti and Mr. diGenova jointly designated William H. Webster (a partner in the firm of Milbank, Tweed, Hadley & McCloy) to continue serve as the third member of the IRB. Mr. Webster was formerly a judge on the United States Court of Appeals, Director of the Federal Bureau of Investigation and Director of the Central Intelligence Agency.

Under the Consent Decree and the Rules approved by the Court, the IRB has authority to hire staff. Pursuant to this authority, the IRB has engaged former Investigations Officer Charles Carberry as Chief Investigator and authorized Mr. Carberry to retain additional investigators and staff. Mr. Carberry and his staff maintain an office in New York City. The IRB maintains a hotline at (800) CALL IRB.
