Issues Involved:
1. Interpretation of Notification No. 14/2010-ST dated 27.2.2010.
2. Applicability of service tax provisions to services provided in the continental shelf and exclusive economic zone of India.
3. Classification of services under Notification No. 21/2009-ST dated 7.7.2009.
4. Retrospective application of the 2010 Notification.
5. Tax liability for services provided by vessels not entirely used in India.
6. Taxability of activities under contracts entered into prior to 7.7.2009.

Issue-wise Detailed Analysis:

1. Interpretation of Notification No. 14/2010-ST dated 27.2.2010:
The core issue was whether Notification No. 14/2010-ST dated 27.2.2010 was clarificatory/declaratory or introduced a substantive change in law. The court analyzed the legislative intent and the language of the notification. It concluded that the 2010 Notification brought about a substantive change by expanding the tax net to include services related to the construction of installations, structures, and vessels for the purpose of prospecting or extraction or production of mineral oil and natural gas. This was a significant departure from the previous notifications, which only covered services to installations, structures, and vessels.

2. Applicability of Service Tax Provisions to Services Provided in the Continental Shelf and Exclusive Economic Zone of India:
The court examined the extension of service tax provisions to the continental shelf and exclusive economic zone of India through various notifications. Initially, the 2002 Notification extended service tax provisions to designated areas as per the 1986 and 1996 notifications. The 2009 Notification further extended these provisions to installations, structures, and vessels in the entire continental shelf and exclusive economic zone. However, the 2010 Notification significantly widened the scope to include services for all activities related to the construction of installations, structures, and vessels for prospecting or extraction of mineral oil and natural gas.

3. Classification of Services Under Notification No. 21/2009-ST dated 7.7.2009:
The court found that the 2009 Notification covered services rendered to installations, structures, and vessels in the continental shelf and exclusive economic zone of India. The appellant's services, which involved providing offshore drilling rigs for mineral oil prospecting, did not fall under this notification as they were not services rendered to installations, structures, or vessels but were consumed by the seabed of the continental shelf.

4. Retrospective Application of the 2010 Notification:
The court held that the 2010 Notification could not be considered clarificatory or declaratory in nature. It brought about a substantive change in the law and, therefore, could not be applied retrospectively. The court emphasized that tax laws must be clear and unambiguous, and any change that introduces new tax liabilities must be applied prospectively unless explicitly stated otherwise.

5. Tax Liability for Services Provided by Vessels Not Entirely Used in India:
The court did not delve deeply into this issue, as it had already determined that the appellant's services were not taxable under the 2009 Notification. The focus remained on the interpretation and applicability of the notifications rather than the specific use of the vessels.

6. Taxability of Activities Under Contracts Entered Into Prior to 7.7.2009:
Given the court's conclusion that the appellant's services were not taxable under the 2009 Notification, it found it unnecessary to address the issue of taxability of activities under contracts entered into before 7.7.2009. The primary determination was that the services in question did not fall under the purview of the 2009 Notification, making the timing of the contracts irrelevant.

Conclusion:
The court allowed the appeal, holding that the transactions involved did not fall under the 2009 Notification and that the 2010 Notification brought about a substantive change in the law, which could not be applied retrospectively. As a result, the tax demand against the appellant was not justified.
