OSC will claim exemptions from the provisions of the Privacy Act at subsections (c)(3) and (d) as permitted by subsection (k) for records subject to the act that fall within the category of investigatory material described in paragraphs (2) and (5) and testing or examination material described in paragraph (6) of that subsection. The exemptions for investigatory material are necessary to prevent frustration of inquiries into allegations in prohibited personnel practice, unlawful political activity, whistleblower disclosure, Uniformed Services Employment and Reemployment Rights Act, and other matters under OSC's jurisdiction, and to protect identities of confidential sources of information, including in background investigations of OSC employees, contractors, and other individuals conducted by or for OSC. The exemption for testing or examination material is necessary to prevent the disclosure of information which would potentially give an individual an unfair competitive advantage or diminish the utility of established examination procedures. OSC also reserves the right to assert exemptions for records received from another agency that could be properly claimed by that agency in responding to a request. OSC may also refuse access to any information compiled in reasonable anticipation of a civil action or proceeding.
