Confidential information protection permits Director General to withhold disclosure, require non-confidential summaries, or disregard unwarranted claims. Rule 7 provides that inherently confidential information or information provided on a confidential basis shall, upon cause shown, be treated as confidential by the Director General and not disclosed without the supplier's authorisation; the Director General may require a non-confidential summary or reasons why summarisation is impossible, and may disregard information if confidentiality is not warranted unless independently verified from appropriate sources.
