"57. The term "unauthorized use of electricity" is defined in explanation (b) to Section 126 which includes usage of electricity (i) by any artificial means; or (b) by a means not authorised by the concerned person or authority or licensee; or (iii) through a tampered meter; or (iv) for the purpose other than for which the usage of electricity was authorised. Before issuing an assessment notice, therefore, the assessing officer must record its conclusion that the person concerned or any other person benefited has used electricity unauthorizedly in terms as defined in Explanation (b) of Section 126. The Act in respect to the stage of recording of conclusion by assessing officer regarding user of electricity by the person unauthorizedly does not provide specifically for any opportunity of hearing to the person concerned but also simultaneously does not prohibit the same. The allegation of unauthorised use of electricity by a person concerned, as defined in Explanation (b) also covers within its ambit certain acts/omission which constitute an offence under Section 135 of the Act, 2003. Therefore, it is a serious matter and no person can be indicted and held guilty of user of electricity unauthorizedly unless he is given an opportunity of hearing before coming to such conclusion. Where a person is held guilty of unauthorised user of electricity, besides making him responsible for paying penalty in the shape of assessment under the Act, 2003 it also causes stigma on his conduct. He is declared an anti-social person indulging in a serious unsocial activity, by causing loss to the society and country in general and electricity undertaking in particular. Such condemnation of a person would not be permissible on the mere vagaries of the authority i.e. assessing officer unless such a person is given a fair opportunity of hearing i.e. putting his defence before the said authority. This Court is clearly of the view that before making provisional assessment, the assessing officer, in law, is bound to afford an opportunity to the consumer or person concerned of the allegations of means and ways in which he is said to have unauthorizedly used electricity, and, should be given an opportunity of placing his defence. Thereafter the assessing officer shall record its conclusion with respect to unauthorised use of electricity, to confer upon himself the jurisdiction to issue provisional assessment notice. The object of opportunity at the two stages namely, before arriving at the conclusion of unauthorised use of electricity and before making final assessment are distinct. In the former, it is the very issue whether the consumer is guilty of unauthorised use of electricity or not and in later case it is the quantum of amount which
