The petitioner is not a regular employee of the Power Corporation. He has been engaged through a contractor/respondent no. 3. The petition is thus an employee of a private organization entity which is not an instrumentality of State within the meaning of Article 12 of the Constitution of India. In this wake the petitioner cannot be permitted to assail the reallocation of work made to him by his contractor. The action has been taken by the respondent no. 3 in terms of a contract between the Power Corporation and the respondent no. 3. In case the contractor is not satisfied, the services of the petitioner may be discontinued. No writ petition is maintainable at the behest of the petitioner.
