Popular and commercial meaning governs exemption notifications; soap-stone was treated as talc, and departmental instructions could not bind adjudication.

In interpreting an exemption notification under fiscal law, the Court applied the popular and commercial meaning of the commodity and held that soap-stone falls within "talc" for the purpose of the notification, so exemption is available if the prescribed conditions of use are satisfied. The Court also held that a departmental or ministerial communication cannot conclusively determine the exemption issue or control the independent judgment of statutory authorities under the Central Excise law. The result was in favour of the assessee, with refund and consequential relief left to follow upon fulfilment of the notification conditions.

Issues: (i) Whether soap-stone is included in the word "talc" in Exemption Notification No. 23/55-C.E. dated 29 April 1955 so as to entitle the assessee to exemption from excise duty when used as extender, suspending agent, filler or diluent; (ii) whether the administrative decision communicated by the department could conclusively determine the exemption question or control the statutory authorities under the Central Excise law.

Issue (i): Whether soap-stone is included in the word "talc" in Exemption Notification No. 23/55-C.E. dated 29 April 1955 so as to entitle the assessee to exemption from excise duty when used as extender, suspending agent, filler or diluent.

Analysis: The word used in a taxing or exemption entry must be construed in its popular and commercial sense, as understood by persons dealing with the commodity, and not in a narrow technical or scientific sense. On the materials placed before the Court, including mineral literature, departmental references, trade usage, and the mineral classification under the Minor Mineral Concession Rules, talc, steatite and soapstone were treated as the same mineral or as different varieties of the same mineral. The prior departmental clarification also stated that the benefit of the notification could be extended to soapstone if the specified conditions were satisfied.

Conclusion: Soap-stone is included in the word "talc" and is entitled to the benefit of the exemption notification, if the prescribed conditions of use are fulfilled; the finding is in favour of the assessee.

Issue (ii): Whether the administrative decision communicated by the department could conclusively determine the exemption question or control the statutory authorities under the Central Excise law.

Analysis: The power to decide the levy and exemption issue vested in the statutory authorities under the Act, not in an administrative direction from the Ministry. A quasi-judicial authority must exercise its own judgment independently and cannot have its decision controlled by departmental instructions or a prior administrative view. The impugned communication therefore could not override the statutory process or bind the adjudicating authority.

Conclusion: The Ministry's communication had no jurisdiction to finally decide the exemption dispute or to control the statutory authorities; this issue is decided in favour of the assessee.

Final Conclusion: The petitions succeeded in part by securing recognition that soap-stone falls within talc for the exemption, and the matter was left for refund and consequential relief upon satisfaction of the notification's conditions.

Ratio Decidendi: In interpreting an exemption notification in fiscal law, the decisive test is the popular and commercial meaning of the commodity, and an administrative direction cannot supplant the independent judgment of the statutory adjudicating authority.
