“The Commission has taken note of Section 54 of the Act, which provides that the Central Government may, by notification, exempt from the application of the Act, or any provision thereof, and for such period as it may specify in such notification, inter alia, "any enterprise which performs a sovereign function on behalf of the Central Government or a State Government" (See Section 54(c)). Pertinently, no notification has been issued by the Central Government in relation to the services rendered by the Indian Railways. Even in relation to an enterprise which is engaged in activity, including an activity relatable to the sovereign function of the Government, the Central Government may grant exemption only in respect of activity relatable to sovereign functions. Therefore, an enterprise may perform some sovereign functions, while other functions performed by it, and the activities undertaken by it, may not refer to sovereign functions. The exemption under Section 54 could be granted in relation to the activities relatable to sovereign functions of the Government, and not in relation to all the activities of such an enterprise. Pertinently, there is no notification issued under Section 54 either under Clause (c), or under the proviso. This clearly shows that the Central Government does not consider any of the activities of the petitioner as relatable to sovereign functions.”.
