Public law review applies to stock exchange settlement decisions; temporary postponement for suspected fraud is valid, but not indefinite.

A stock exchange performing settlement and clearing functions was held amenable to judicial review under Article 226 because its regulatory bye-laws operate in the public interest and discharge a public duty. On the merits, the initial postponement of a settlement was justified where the exchange had relevant material suggesting suspected fraud or market manipulation and its regulations permitted postponement in public interest or on just and equitable principles of trade; however, that postponement could not continue indefinitely and had to end in a final decision. The alternative contractual remedy objection was rejected because no final settlement decision had yet crystallised, so an effective remedy was not then available.

Issues: (i) whether the stock exchange was amenable to writ jurisdiction under Article 226 of the Constitution of India in relation to its settlement and clearing functions; (ii) whether the postponement of Settlement No. 27 in respect of the scrip of Maruti Organics Ltd. was justified under the exchange regulations and the securities law framework; (iii) whether the petitioners were bound to pursue an alternative contractual remedy before invoking writ jurisdiction.

Issue (i): Whether the stock exchange was amenable to writ jurisdiction under Article 226 of the Constitution of India in relation to its settlement and clearing functions.

Analysis: The exchange was registered under the securities regulatory statute, its bye-laws and regulations operated in the public interest, and the functions of assisting, regulating and controlling dealings in securities carried a public duty. A body performing such public functions is subject to judicial review when its decision affects market participants and investors.

Conclusion: Yes. The exchange was amenable to writ jurisdiction under Article 226 of the Constitution of India.

Issue (ii): Whether the postponement of Settlement No. 27 in respect of the scrip of Maruti Organics Ltd. was justified under the exchange regulations and the securities law framework.

Analysis: The materials before the exchange disclosed complaints of suspected fraud and market manipulation. Regulation 2.16 of the Capital Market Trading Regulations authorised postponement of performance of contracts where the Executive Committee considered it necessary in public interest or on just and equitable principles of trade. The Court held that it could not sit in appeal over the adequacy of material once some relevant basis existed, but also emphasised that such postponement could only be temporary and could not continue indefinitely.

Conclusion: Yes, the initial postponement was justified, but the settlement could not remain postponed indefinitely and a final decision had to be taken.

Issue (iii): Whether the petitioners were bound to pursue an alternative contractual remedy before invoking writ jurisdiction.

Analysis: The petitioners' grievance arose from the exchange's postponement of settlement, and no final settlement decision had yet been taken. Until such decision was made, no enforceable settlement dispute against the brokers or the clearing corporation had crystallised. The contractual redress mechanism was therefore not an effective or available remedy at that stage.

Conclusion: No. The alternative remedy objection was rejected.

Final Conclusion: The writ petitions succeeded only to the extent of securing a direction to the exchange to take a final decision on the postponed settlement within the time fixed by the Court; the challenge to the interim postponement itself was not accepted.

Ratio Decidendi: A stock exchange performing public regulatory functions is amenable to judicial review under Article 226, and where relevant material indicates suspected fraud or market manipulation, it may temporarily postpone settlement in public interest under its regulations, but such postponement cannot be indefinite and must culminate in a final decision.
