5. In the facts and circumstances, this Court cannot appreciate the action of the petitioners in making their own calculations, even though this Court in WP No.8444 of 2000 & batch dated 08.08.2008 directed the respondents to make calculations and determine whether any consumer is entitled for refund of the amounts or the respondents can demand the amounts payable by the consumers. The said exercise has to be done by the respondents, but the petitioners, on their own cannot unilaterally do the exercise and withhold the payments of the amounts due to the respondents. Though, learned standing counsel for the respondents, states that the calculations were made subsequently and demand notices were issued to the individual consumers, learned counsel for the petitioners states that they have not received any demand notices and if the respondents issued demand notices, they would take appropriate steps challenging the same.
