Territorial writ jurisdiction and exemption limits cannot be expanded by mere local connection or promissory estoppel.

Territorial writ jurisdiction depends on a real and material part of the cause of action arising within the Court's limits; mere receipt of a notification, location of a registered office, or alleged local loss is insufficient where the authorities complained against are elsewhere. A clear exemption notification cannot be extended beyond its express period by promissory estoppel or ministerial assurance, especially when the notification itself states a fixed end date and the claimed benefit arises after expiry. The commentary concludes that both territorial jurisdiction and the substantive exemption claim fail on these principles.

Issues: (i) Whether the High Court had territorial jurisdiction to entertain the writ petition on the pleaded facts. (ii) Whether the writ petitioners could claim exemption beyond the life of the notification on the basis of promissory estoppel or ministerial assurance.

Issue (i): Whether the High Court had territorial jurisdiction to entertain the writ petition on the pleaded facts.

Analysis: Jurisdiction under the writ jurisdiction depended on a material part of the cause of action having arisen within the Court's territorial limits. Mere receipt of a gazetted notification within the jurisdiction, the location of the registered office, or an alleged loss claimed to have been suffered there did not by themselves constitute essential facts for obtaining relief. The excise authorities against whom the grievance was really directed were outside the jurisdiction, and the pleaded Calcutta-based connections were insufficient to found jurisdiction.

Conclusion: The writ petition was not maintainable before the High Court for want of territorial jurisdiction.

Issue (ii): Whether the writ petitioners could claim exemption beyond the life of the notification on the basis of promissory estoppel or ministerial assurance.

Analysis: The exemption notification expressly operated only up to 31st March, 1984. The plant commenced production after the expiry of that period, so the benefit could not arise on the facts. A ministerial statement could not override the clear terms of a statutory notification issued under Rule 8(1) of the Central Excise Rules, 1944. Where the notification was unambiguous, promissory estoppel could not be used to enlarge or continue the exemption beyond its stated duration.

Conclusion: The writ petitioners were not entitled to the claimed exemption beyond the notification period.

Final Conclusion: The challenge to the interim orders failed on both jurisdictional and substantive grounds, and the orders under appeal were set aside.

Ratio Decidendi: In writ proceedings, territorial jurisdiction must rest on a real and material part of the cause of action, and a clear exemption notification cannot be extended beyond its express period by promissory estoppel or executive assurance.
