Petitioner is a practicing lawyer at Ernakulam. Since he hails from Pathanamthitta, he is staying in first floor, 'Theertham', St. Benedict Road, West end, Cochin-18, which was taken on rent and is being used as an office cum residence. The consumer number given by the KSEB with respect to the first floor of the building is 5546001851. A notice was issued to the petitioner on 23-2-2007 informing the change of tariff from LT I(a) to LT VI(b) and therefore he has to remit an amount of Rs.1841/- towards electricity charges. Later Ext.P4 bill showing an amount of Rs.1699/- was issued. Both these bills were paid by the petitioner under protest. Peitioner has got a specific case that he is not liable to pay the amounts as required by the respondent Board. Learned counsel for the petitioner submits that ever since the Electricity Act, 2003 came in to force, it is no longer open to the Board to unilaterally change the tariff. Still further, the petitioner was not at all heard before any decision is taken in this regard.
