4.4. It is contended by Mr. S.K. Kejriwal, learned counsel for the petitioner, that Rule 6 of the Electricity (Rights of Consumers) Rules, 2020 is framed by the Central Government in exercise of the statutory powers conferred by SubSection (1) read with clause (z) of Sub-Section (2) of Section 176 of the Electricity Act, 2003. Rule 6(1) of the said Rules deals with 'Billing and Payment' and provides that Tariff for each category of consumers shall be displayed on distribution licensee's website and consumers shall be notified of change in tariff including fuel surcharge and other charges, a full billing cycle ahead of time, through distribution licensee's website as well as through energy bills.

Further, Rule 6(10) of aforesaid Rules provides that no bill can be issued after expiry of 60 days and if any bill is issued not exceeding 60 days, the consumer is entitled to rebate of
