Investigation by Director General: report submission and confidential case record rules govern Commission inquiries and supplementary probes. The Secretary must forward the information or reference and all related documents to the Director General when the Commission issues directions. The Commission specifies a time for the Director General to submit a report, which must set out findings and include all evidence and analyses forming the case record. The Director General may submit a two-part report and case record to protect confidential material, and must provide multiple hard copies and an electronic pdf to the Secretary; the Commission may require supplementary investigation on specified issues.
