An interested party may request the hearing officer to review the assessment of the Commission services responsible for the investigation on whether a non-confidential summary of confidential information submitted in the course of an investigation is in sufficient detail to permit a reasonable understanding of the substance of the information submitted in confidence.

If the Commission services responsible for the investigation intend to disregard a document or information for which an interested party has refused to provide a meaningful non-confidential summary, the latter may request the hearing officer to decide on the matter.

The hearing officer shall examine the request. If he considers that the non-confidential summary is not sufficiently detailed, the hearing officer shall give the interested party that provided the summary an opportunity to comment and improve its summary within a reasonable time.

If the interested party that submitted the confidential information provides a deficient summary, provides justifications that cannot be accepted, or does not act, the hearing officer shall decide whether or not to disregard confidential information for which no meaningful non-confidential summary has been provided in accordance with the relevant provisions of the basic Regulations.
