Appeal to the High Court is permitted from specified competent authority orders on compensation awards, interest or damages, redemption refusals, distribution among dependants, indemnity claims and registration of memoranda; appeals require a substantial question of law and, except for redemption refusals, a prescribed monetary threshold, are barred where parties agreed to abide by the authority's decision or the order reflects such agreement, an employer's appeal must be accompanied by a certificate of deposit of the payable amount, and the limitation period is sixty days with the Limitation Act applying.
