Area-based exemption survives later product changes when the same plant and machinery was installed and used within the prescribed time.

An area-based exemption under Notification No. 39/2001 remains available where the unit was set up within the stipulated period, the required plant and machinery were installed, and commercial production commenced by 31-12-2005. Later manufacture of additional or disputed products does not, by itself, forfeit the benefit if those products were made using the same plant and machinery already installed and put to use within time. The operative test is timely compliance with the notification's conditions, not a later change in product mix. The exemption is therefore preserved where the original industrial unit met the prescribed time-based requirements and continued operations on the same machinery.

Issues: Whether the assessee remained eligible for area-based exemption under Notification No. 39/2001 dated 31-07-2001 when some of the disputed products were manufactured after the cut-off date, but were produced using the same plant and machinery installed and commercial production commenced before 31-12-2005.

Analysis: The notification required that the unit be set up within the stipulated time, plant and machinery be installed, and commercial production commence by 31-12-2005. The undisputed facts showed that the machinery had been installed and commercial production had begun within time. The only controversy was whether later manufacture of particular products disqualified the assessee from exemption. The Board's clarification, relied upon by the Commissioner, indicated that where products are manufactured after the cut-off date using the same plant and machinery already installed, the exemption is not lost merely because the product mix changes later. The purpose of the notification was to encourage investment and industrial growth in the specified area, and the decisive consideration was whether the unit satisfied the stipulated conditions within time and used the same plant and machinery.

Conclusion: The assessee satisfied the conditions of the exemption notification and remained entitled to the benefit notwithstanding later production of the disputed goods.

Final Conclusion: The Revenue's challenge failed because the exemption conditions were met and the later manufacture of additional products did not defeat the benefit where the same plant and machinery had already been installed and put to use within the prescribed period.

Ratio Decidendi: Under an area-based exemption notification, subsequent manufacture of additional products does not by itself defeat eligibility if the unit had installed the required plant and machinery and commenced commercial production within the stipulated time using the same machinery.
