(a) When an awardee institution or another Federal agency has promptly initiated its own investigation, the OIG may defer its inquiry or investigation until it receives the results of that external investigation. When the OIG does not receive the results within a reasonable time, the OIG shall ordinarily proceed with its own investigation.

(b) When the OIG decides to initiate a NASA investigation, the OIG must give prompt written notice to the individual or institution to be investigated, unless notice would prejudice the investigation or unless a criminal investigation is underway or under active consideration. If notice is delayed, it must be given as soon as it will no longer prejudice the investigation or contravene requirements of law or Federal law-enforcement policies.

(c) When alleged misconduct may involve a crime, the OIG shall determine whether any criminal investigation is already pending or projected. If not, the OIG shall determine whether the matter should be referred to the Department of Justice.

(d) When a criminal investigation by the Department of Justice or another Federal agency is underway or under active consideration, the OIG shall determine what information, if any, may be disclosed to the Respondent or to NASA employees.

(e) To the extent possible, the identity of sources who wish to remain anonymous shall be kept confidential. To the extent allowed by law, documents and files maintained by the OIG during the course of an inquiry or investigation of misconduct shall be treated as investigative files exempt from mandatory public disclosure upon request under the Freedom of Information Act.

(f) When the OIG proceeds with its own inquiry, it is responsible for ensuring that the inquiry is completed within 60 days after it is commenced. The OIG may extend this period of time for good cause.

(g) On the basis of what the OIG learns from an inquiry, and in consultation as appropriate with other NASA offices, the OIG shall decide whether a formal investigation is warranted.
