Investment ceiling under small-scale industry rules requires independent verification, and manufacturing equipment used in production counts toward plant and machinery.

Rule 3(66a) of the Bengal Sales Tax Rules, 1941 requires both registration with the Cottage and Small Scale Industries Department and compliance with the prescribed investment ceiling, so the sales tax authority must independently verify whether investment in plant and machinery exceeds the limit; the S.S.I. registration certificate is not conclusive. A water treatment plant used at stages of the manufacturing process was held includible in plant and machinery because the project materials showed use in production, not merely for drinking water, and its cost pushed investment beyond the ceiling. The challenge based on breach of natural justice also failed, as no denial of hearing was established.

Issues: Whether the Small Scale Industries registration certificate was conclusive for determining investment on plant and machinery under rule 3(66a) of the Bengal Sales Tax Rules, 1941; whether water treatment plant formed part of plant and machinery for the purpose of the investment ceiling; and whether the challenge based on breach of natural justice could succeed.

Issue (i): Whether the Small Scale Industries registration certificate was conclusive for determining investment on plant and machinery under rule 3(66a) of the Bengal Sales Tax Rules, 1941.

Analysis: Rule 3(66a) required not only registration with the Cottage and Small Scale Industries Department but also that the investment on plant and machinery should not exceed the prescribed limit. The Tribunal held that the sales tax authority was obliged to independently determine whether the investment crossed the statutory ceiling and could not treat the S.S.I. certificate as conclusive. The absence of departmental guidelines did not make the certificate binding on the assessing authority.

Conclusion: The contention was rejected and the authority was entitled to examine the investment on plant and machinery independently.

Issue (ii): Whether water treatment plant formed part of plant and machinery for the purpose of the investment ceiling.

Analysis: On the materials in the project report and the factual record, water was used at stages of the manufacturing process with chemicals and for treatment of the galvanised sheets. The Tribunal found that the plea that the plant was installed only for drinking water could not be accepted, as it had not been taken earlier and was inconsistent with the project report. The water treatment plant was therefore treated as used in the manufacturing process and includible in plant and machinery. Once its cost was added, the investment exceeded the prescribed ceiling.

Conclusion: The water treatment plant was held to be part of plant and machinery, and the assessee failed on this issue.

Issue (iii): Whether the challenge based on breach of natural justice could succeed.

Analysis: The Tribunal found no sufficient basis to hold that the applicant had been denied a hearing on the manner of use of the relevant equipment. The objection had not been taken in the earlier revision, and the applicant had had an effective opportunity to argue the point before the appellate authority. The plea of violation of natural justice was therefore not sustained.

Conclusion: The natural justice challenge was rejected.

Final Conclusion: The statutory investment limit was found to have been crossed on the inclusion of the water treatment plant, and no procedural infirmity was established to disturb the concurrent findings below.

Ratio Decidendi: Where the statute prescribes both registration and a monetary ceiling for eligibility, the competent authority must independently verify the ceiling, and equipment integral to the manufacturing process is includible in plant and machinery for that purpose.
