Appeals under the Code on Wages permit challenges to section 45 orders within ninety days, with appellate review and recovery mechanisms. Section 49 permits any person aggrieved by an order under section 45 to appeal to an appellate authority appointed by the appropriate Government within ninety days, subject to extension for sufficient cause. The appellate authority must be an officer at least one rank higher, hear the parties and endeavour to dispose of appeals within three months. Outstanding dues under appellate orders are to be recovered by the authority under section 45 through a certificate of recovery as specified in sub section (3) of that section.
