At the direction or request of the Legislature by concurrent resolution or of the Governor or of the head of any department, board, bureau, commission, authority or other agency created by the State, or to which the State is a party, the commission shall investigate the management or affairs of any such department, board, bureau, commission, authority or other agency; provided, however, that if the commission determines that the requests for investigations from the Legislature, the Governor or the head of any department, board, bureau, commission, authority or other agency created by the State or to which the State is a party, exceed the commission's capacity to perform such investigations, they may, by resolution, ask the Governor or the Attorney General or the Legislature in the case of a legislative request, to review those requests upon which it finds itself unable to proceed.
