' JAVED IQBAL, J.---By this order we propose to dispose of the above captioned petitions for leave to appeal which are directed against the judgment, dated"' 5-4-2002 passed, by the learned Single Judge in Chambers of the Lahore High Court, Lahore, whereby the writ petitions have been disposed of in the following terms:--- "6. In the said facts and circumstances both the writ petitions are disposed of with the direction that till such time the Ministry of Finance and Wapda work out the manner and made in which the matter of refund are to be implemented in terms of the said notification, dated 5-1-2000 in respect of all domestic, commercial and agricultural consumers consuming less than 500 units, sales tax to the extent of 5% of the total consumers utilizing the electricity through the petitioner Society shall be levied and recovered by Wapda from the petitioner Society. This shall, however, be subject to regular check by Wapda on the matter of further supplies of electricity by the petitioner to its said members including the consumers falling in the, said category and Wapda shall be at liberty to adjust the bills in accordance with the results of the said inspection. After the decision had been taken by the Ministry of Finance and Wapda as to the modality of refund etc., the matter will be governed accordingly."
2. A bare perusal of the operative portion of the judgment impugned as reproduced hereinabove would reveal that the controversy revolves around the levy and collection of tax which should have not been decided without, impleading the Collector of Sales Tax concerned which admittedly is a necessary party without whose impleadment the IA controversy cannot be set at naught properly and effectively.
3 Mr. Zia Haider Rizvi, learned Advocate Supreme Court for caveators could not satisfy on the point that the dispute in question could have been resolved without impleading the Collector of Sales Tax as a party.
4. In sequel to the foregoing discussion these petitions are converted into appeal which are accepted by setting aside the judgment impugned with the direction to decide the matter afresh by impleading the Collector of Sales Tax and Central Excise Lahore as necessary party after affording proper opportunity of hearing to all concerned.
