Appeal to High Court preserves review of designated court decisions in SEZ matters, subject to time limits and cause-based extensions. An aggrieved person may appeal to the High Court against any decision or order of the court designated under the SEZ appellate scheme on any question of fact or law arising from such orders. The appeal must be filed within the prescribed appeal period from communication of the designated court's order, though the High Court may allow a delayed filing if satisfied the appellant was prevented by sufficient cause, within a further limited extension. 'High Court' means the High Court of the State where the Special Economic Zone is situated.
