The binding principles established are: (1) Regulations 25 and 26 of the Anti-Dumping Regulations, which require verification of information before initiation, apply only to original anti-dumping investigations and not to sunset reviews. A sunset review may be initiated based on 'a proper application' containing 'necessary information' establishing a prima facie case, with verification permitted during the subsequent investigation phase. (2) An applicant seeking condonation for failure to comply with PAJA's 180-day rule must provide a full and reasonable explanation covering the entire period of delay, and must also explain any delay in seeking condonation itself. (3) The Minister of Trade, Industry and Competition is not required to afford parties a hearing before accepting or rejecting ITAC's recommendations under s 4(2) of the BTT Act, where those parties have already had an opportunity to make representations to ITAC. The Minister's role is to consider policy factors relating to international trade, not to reconsider ITAC's investigative process. (4) The setting, changing or removal of anti-dumping duties by the Minister of Finance constitutes executive action, not administrative action, and is therefore subject only to legality review and not to requirements of procedural fairness, where ITAC has already afforded parties procedural fairness in its investigation.
