The United States Office of Special Counsel investigates allegations of certain activities prohibited by civil service laws, rules, or regulations and litigates before the Merit Systems Protection Board.

The U.S. Office of Special Counsel (OSC) was established on January 1, 1979, by Reorganization Plan No. 2 of 1978 (5 U.S.C. app.). The Civil Service Reform Act of 1978 (5 U.S.C. 1101 note), which became effective on January 11, 1979, enlarged its functions and powers. Pursuant to provisions of the Whistleblower Protection Act of 1989 (5 U.S.C. 1211 et seq.), the OSC functions as an independent investigative and prosecutorial executive branch agency that litigates before the Merit Systems Protection Board.


The OSC safeguards the merit system in Federal employment by protecting employees and applicants from prohibited personnel practices, especially from reprisal for whistleblowing. The Office operates a secure channel for Federal whistleblower disclosures of gross waste of funds or mismanagement, substantial and specific danger to public health and safety, and violations of laws, regulations, or rules. The OSC also issues advice on the Hatch Act and enforces its restrictions on political activity by Government employees. It protects the civilian employment and reemployment rights of military servicemembers under the Uniformed Services Employment and Reemployment Act. The OSC enhances Government accountability and performance by the realization of a diverse, inclusive Federal workplace where employees embrace excellence in service, uphold merit system principles, are encouraged to disclose wrongdoing, and are protected against reprisals and other unlawful employment practices.
