Annual turnover under Schedule III means gross securities turnover; later writ challenge barred by res judicata and constructive res judicata.

A writ challenge to the stockbroker registration-fee levy was held barred by res judicata and constructive res judicata because the earlier Supreme Court proceedings had already addressed the same levy in substance, and matters that might and ought to have been raised then could not be reopened. On merits, "annual turnover" under Schedule III was construed in its plain and contextual sense as the aggregate sale and purchase prices of securities received and receivable during the financial year, not merely the net difference or brokerage element. The differing wording used for derivatives in another schedule did not control this provision. The levy and the registration-fee demand were therefore sustained.

Issues: (i) Whether the writ petition was barred by res judicata or constructive res judicata in view of the earlier Supreme Court proceedings concerning the same levy. (ii) Whether, for the purposes of registration fees under Schedule III, the expression "annual turnover" meant the aggregate sale and purchase prices of securities received and receivable by the stockbroker, or only the net difference between purchase and sale values.

Issue (i): Whether the writ petition was barred by res judicata or constructive res judicata in view of the earlier Supreme Court proceedings concerning the same levy.

Analysis: The prior Supreme Court decision had already upheld the levy based on annual turnover and had considered the challenge to regulation 10 and Schedule III in substance. The principle of res judicata extends not only to issues actually decided but also to matters which might and ought to have been raised in the earlier litigation. The same challenge, though presented with a different emphasis, was held to fall within that bar.

Conclusion: The writ petition was barred by res judicata and constructive res judicata against the petitioner.

Issue (ii): Whether, for the purposes of registration fees under Schedule III, the expression "annual turnover" meant the aggregate sale and purchase prices of securities received and receivable by the stockbroker, or only the net difference between purchase and sale values.

Analysis: The Explanation in Schedule III was read according to its plain language and in the light of the object of the regulatory levy. The expression "annual turnover" was held to refer to the aggregate of sale and purchase prices received and receivable in the financial year, not merely the brokerage or net differential. The contrasting language in Schedule IV for derivatives did not control Schedule III, because the two schedules dealt with different market segments. The interpretation advanced by the petitioner was considered inconsistent with the accepted expert report and would produce an unreasonable and impractical levy structure.

Conclusion: The expression "annual turnover" under Schedule III includes the aggregate sale and purchase prices of securities received and receivable by the stockbroker, and not merely the net difference.

Final Conclusion: The challenge to the levy failed both on the bar of prior adjudication and on merits of interpretation, and the registration-fee demand was sustained.

Ratio Decidendi: A regulatory levy based on "annual turnover" in Schedule III of the SEBI Stock Brokers Regulations is to be construed according to its plain, contextual meaning as the aggregate sale and purchase prices received and receivable, and a subsequent writ challenge on the same levy is barred where the issue was already decided or could and ought to have been raised earlier.
