the stage of notice. High Court ought not to have entertained the writ petition, more so, when against the final orders appeal lies to this Court. The judgment of this Court in the case of Union of India & Anr. v. Guwahati Carbon Ltd. (supra) relied on by the learned senior counsel for the appellants also supports their case. In the aforesaid judgment, arising out of Central Excise Act, 1944, this Court has held that excise law is a complete code in order to seek redress in excise matters and held that entertaining writ petition is not proper where alternative remedy under statute is available. When there is a serious dispute with regard to classification of service, the respondents ought to have responded to the show cause notices by placing material in support of their stand but at the same time, there is no reason to approach the High Court questioning the very show cause notices. Further, as held by the High Court, it cannot be said that even from the contents of show cause notices there are no factual disputes. Further, the judgment of this Court in the case of Malladi Drugs & Pharma Ltd. v. Union of India, relied on by the learned senior counsel for the appellants also supports their case where this Court has upheld the judgment of the High Court which refused to interfere at show cause notice stage.”
