When would the remaining sections of the Act come into force?

Sections 20 and section 43 provides that the Authority and the Appellate Tribunal need to be established within 1 year of the commencement of the Act. As the said sections were notified for commencement on 1st May, 2016 the Authority and the Appellate Tribunal are required to be established maximum by 30th April, 2017. Sections of the Act which have not been notified yet, would be notified maximum upon the expiry of that period.
