Conduct of examination under section 477: Official Liquidator leads examination; court may permit others subject to conditions. Conduct of examinations under section 477 places primary responsibility on the Official Liquidator, though the Court may entrust conduct to a contributory or creditor; the Official Liquidator may nevertheless attend, take notes for his own use and ask questions with the Court's leave. Participation is ordinarily limited to the Official Liquidator and his advocate, but the examinee may have an advocate for re-examination. The Court may allow creditors or contributories to attend on conditions. Notes taken by a witness require an undertaking and are handed to the Court for destruction unless directed otherwise.
