Under the Commission’s Rules, parties may petition for Commission review of an Administrative Law Judge's Initial Determination (ID) if they believe that it (i) contains a clearly erroneous finding of material fact, (ii) contains an erroneous legal conclusion, or (iii) affects Commission policy. Parties may file responses to any petition for review. Within 60 calendar days after service of the ID on the parties, the Commission decides, either on the basis of a petition for review or on its own initiative, whether to review some or the entire ID. Those portions of the ID that are not reviewed by the Commission become the Commission’s determination. If the Commission decides to review some or all of an ID, it may affirm, set aside, or modify the portions of the ID under review. See generally, Rules 210.43-210.45, 19 C.F.R. §§ 210.43-210.45.
