Apart from the above, neither any show cause notice nor any reasons were furnished for raising the present demand. On the other hand, a reading of the Bill discloses that there are no arrears for long time and how these arrears crept up overnight is not known. The impugned demand of Rs.1,00,257/- is in furtherance to the earlier demand of Rs.40,802/- which was paid by the petitioner at the time when he requested for restoration of power supply immediately after purchase of the unit. Further, Section 56(2) of the Act contemplates that no demand shall be made after more than two years from the date it is payable and unless and until they are continuously mentioned as arrears in the previous bills. In the impugned notice, no such mention is made. Therefore, it must be deemed that the present demand is raised beyond the period of limitation. Insofar as the judgment relied upon by the learned counsel for respondents in PASCHIMANCHAL VIDYUT VITRAN NIGAM LTD. v. DVS STEELS AND ALLOYS PVT. LTD (2 supra) is concerned, unless and until there is a clause in the terms and conditions of supply, the respondents could not have raised such demand. Insofar as Clause 8.4 is concerned, admittedly, it has come into force with effect from 6.1.2006. Therefore, clause 8.4 is not applicable to the present case, since the very demand is from January 1992 to April 2005. As of today, no agreement has been entered between the parties and even otherwise, the respondents have admitted that the power supply is being made in the name of previous owner.
