To ensure allegations of fraud, waste, abuse, mismanagement, misconduct, and whistleblower reprisal are properly recorded and routed for action by the appropriate office or agency; to provide assistance services and referrals for non-IG matters; and to provide oversight and training to subordinate IG personnel for Hotline management throughout the Marine Corps.

Discussion of how to file a complaint and remain Anonymous or Confidential.



MCO 5430.1A w/ Admin CH - The act of protecting a complainant’s or witness’s identity, and any information that may lead to the identification of the complainant or witness, to the extent possible under applicable law and regulation.

MCO 5370.8A - Confidentiality is essential to the integrity of the IG process. The identity of case persons, to include complainants and subjects, must be protected from unauthorized or unnecessary disclosure outside of IG channels. The names of complainants will not be forwarded outside of IG channels unless the complainant’s identity is necessary to address the complaint, and the complainant consents. If a complainant elects to remain confidential, IG personnel must explain to them that it may not be possible to fully address their complaint, and give the complainant the opportunity to waive confidentiality. This contact will be documented in a case note. 



The Department of Defense and the Secretary of the Navy Hotlines were designed to focus efforts to combat fraud, waste, and mismanagement throughout DoD and the Navy. The Assistance and Hotline Division will inquire into non-criminal, non-frivolous, and substantive allegations submitted in a timely manner that violate a law, rule, regulation, or standard where no other recourse or process is available related to our mission, as stated above.

Military and civilian personnel often seek IG assistance when faced with adverse action for which another more specific remedy or means of redress is available. For example, many adverse personnel actions taken against civilian employees are able to be appealed to the Merit Systems Protection Board (MSPB) or subject to resolution through agency grievance procedures.  Non-judicial punishment and court-martial actions under the UCMJ are subject to the appellate process within the military judicial system.  Other individual complaints of wrong by military personnel may be handled through Article 138, UCMJ or Article 1150, U.S. Navy Regulations procedures. In such cases, the complainant should be referred to the appropriate authority to resolve the matter.  The IG system is not the "court of first resort" for most matters.

A request for an IG inquiry may arrive in the form of a complaint alleging that a military member has committed an offense punishable under the UCMJ. When such cases indicate the commission of a major crime within the jurisdiction of NCIS, they must be presented the information as described above.  Whenever NCIS declines to investigate the matter, the IG organization should next consider referring the allegation to the alleged violator's commander for action.  See Rules for courts-martial 303 and 306.  A referral is appropriate when the allegation is not one that would normally be the subject of an IG investigation.  When a matter appropriate for an IG investigation could constitute an offense punishable under the UCMJ, close coordination with the convening authority is necessary to ensure the IG investigation does not interfere with any potential or actual judicial action.

The Naval Criminal Investigative Service (NCIS) has authority to investigate allegations that Department of the Navy (DON) civilian or military personnel have committed major crimes. SECNAVINST 5430.107A defines this as any offense punishable under the Uniform Code of Military Justice (UCMJ), or similarly framed federal, state, local, or foreign statutes, by confinement for a term of more than one year (such crimes often are referred to as felonies). Although Inspector General (IG) organizations often investigate standards of conduct violations, many of the standards are derived from Federal felony statutes (see, for example, Office of Government Ethics Regulations at 5 CFR 2635.401 through 503 for a discussion of conflicts of interest based on a criminal statute, 18 USC 208, and conflicts based on agency regulations). In those cases, NCIS should be apprised of the allegations before the IG investigation proceeds.  When NCIS has reason to believe the United States Attorney will not prosecute a case, it may decline jurisdiction in order to permit an IG investigation to proceed.  When a matter appropriate for an IG investigation must be referred to NCIS for investigation pursuant to SECNAVINST 5430.107A, the IG organization should log the case into its tracking system and monitor the progress of the NCIS investigation. Should the NCIS investigation fail to establish a basis for criminal prosecution, NCIS may return the action to the IG organization for such further investigation as may be necessary to permit the responsible authority to determine whether non-criminal (judicial or administrative) action is appropriate.

Many requests for assistance are best handled within the chain of command and should be referred to it for action. It is appropriate to request notification of the action taken. Be alert for systemic problems that would best be addressed through an IG investigation or inspection.

The Board for Correction of Naval Records (BCNR) is the appropriate authority to review allegations of improper fitness reports and other requests for correction of records.

MCO 1610.7A

Complaints of discrimination should be addressed through the command EO/EEO process.  In some cases, sexual harassment may be appropriate for IG inquiry, but all allegations of sexual assault are referred to NCIS or civil authorities, as appropriate.  When allegations of discrimination are mixed with other allegations appropriate for IG inquiry, the IG will inform the complainant which matters the IG organization will investigate, and which should be taken through the EO/EEO process. When the allegations are so intertwined as to make separation inefficient, consultation with EO/EEO investigative personnel is appropriate to decide how to proceed.

MCO 5354.1E W ADMIN CH (military)

MCO 12713.6A (civilian)

Some violations of law or regulations must be investigated by specific organizations outside of the Marine Corps. For example, allegations of Hatch Act violations (18 U.S.C. 594 et.seq: Partisan Political Activities) must be referred to the Office of Special Counsel and in some cases may involve the Merit Systems Protection Board.

The Department of Labor is responsible for investigation of many matters relating to wages and hours of work. Some outside organizations have special or unique powers to help. For example, the Office of the Special Counsel can seek a stay of a pending personnel action it believes is based on a prohibited personnel practice.

When an outside organization such as the Office of Special Counsel initiates an investigation into a matter that is already the subject of an IG investigation, it may be appropriate to suspend the IG investigation pending the outcome of the external investigation.

The fact that an individual believes he or she has been wronged by "the system" is not itself sufficient to justify an IG investigation. IGs are not a substitute for the chain of command and other dispute resolution mechanisms, and should not be used for that purpose unless there is evidence those systems are being misused or are malfunctioning. Complaints from individuals seeking relief from adverse personnel or disciplinary actions, unfavorable findings in EO/EEO investigations, or other matters for which the chain of command provides a review mechanism, should be accepted for IG investigation only when coupled with a non-frivolous allegation that the chain of command is unable or unwilling to address the matter fairly and impartially.
