Which one of the following is NOT a power of the Competition Commission of India ?

The Commission has no general statutory power to review its own orders: the provision granting that power was omitted in 2007. It may still rectify a mistake apparent from the record under section 38, but rectification cannot change the substantive part of an order. Inquiry into conduct outside India affecting competition in India, interim restraint, and recovery of unpaid monetary penalties remain statutory powers.
