(a) When information comes to the attention of the General Counsel suggesting that a prohibited personnel practice may have occurred, exists or is to be taken, the General Counsel shall investigate the matter to the extent necessary to determine whether there are reasonable grounds to believe that a prohibited personnel practice has occurred, exists or is to be taken.

(b) If the General Counsel terminates any investigation under this section which is not also the subject of a charge, the General Counsel shall prepare and transmit to any person on whose allegation the investigation was initiated, a written statement notifying the person of the termination of the investigation and the reasons therefore.

(c) If the General Counsel determines that there are reasonable grounds to believe that a prohibited personnel practice has occurred, exists or is to be taken which requires corrective action and which is not also the subject of a charge, the General Counsel shall report the determination together with any findings or recommendations to the GAO.
