Finality of statutory orders bars later representations, and exemption periods cannot be extended without rule-based authority.

A statutory order that was appealable but not challenged attains finality, and later representations cannot reopen the dispute where the Act and Rules provide a complete code; the challenge therefore failed. The governing exemption rules contained no provision to extend or alter the eligibility period from the date of certificate issuance, so no further exemption period was permissible and that claim failed. A discrimination plea based on another unit also failed because that case arose under a different exemption regime and the relevant amendment was not challenged.

Issues: (i) Whether the petitioner could reopen the concluded order by filing subsequent representations after failing to avail the statutory appeal against the order rejecting refund and extension of exemption period. (ii) Whether the Rules permitted extension of the eligibility or exemption period from the date of issuance of the certificate instead of the date of production. (iii) Whether the plea of discrimination based on another unit could succeed without challenging the amendment applicable to that unit.

Issue (i): Whether the petitioner could reopen the concluded order by filing subsequent representations after failing to avail the statutory appeal against the order rejecting refund and extension of exemption period.

Analysis: The order passed by the Excise and Taxation Commissioner on 13.10.2003 was appealable under Section 20 of the Punjab General Sales Tax Act, 1948. The petitioner did not challenge that order and allowed it to attain finality. Subsequent representations made years later could not displace the effect of the concluded order, especially when the Act and the Rules constituted a complete code and statutory remedies were available. Once the dispute stood settled, later communications and orders based on such representations did not revive the matter.

Conclusion: The petitioner could not reopen the matter by subsequent representation, and the objection to maintainability was accepted against the petitioner.

Issue (ii): Whether the Rules permitted extension of the eligibility or exemption period from the date of issuance of the certificate instead of the date of production.

Analysis: The Court noted that the petitioner had already availed the exemption for the period for which it was entitled under the certificate. No provision in the Punjab General Sales Tax (Deferment and Exemption) Rules, 1991 provided for extension of the eligibility period or alteration of the dates on which exemption operated. The challenge to the note appended to Rule 4(1) and the request to read down Rule 3(2) was raised after long delay, when the entitlement had already worked itself out, and no legal basis for extending the period was shown.

Conclusion: No extension of the exemption or eligibility period was permissible, and the challenge failed against the petitioner.

Issue (iii): Whether the plea of discrimination based on another unit could succeed without challenging the amendment applicable to that unit.

Analysis: The comparison with M/s Godrej & Boyce Mfg. Co. Ltd. was rejected because that matter related to deferment of tax, not exemption, and involved an amendment to the Rules. The petitioner had not challenged the amended provision relevant to that case. In the absence of identity of legal regime and challenge to the applicable amendment, parity could not be claimed.

Conclusion: The discrimination argument was not accepted and gave no relief to the petitioner.

Final Conclusion: The Court upheld the rejection of the petitioner's claims and found no merit in the challenge to the orders or the Rules, resulting in dismissal of the petition.

Ratio Decidendi: Where a statutory order has attained finality and the governing rules contain no provision for extension or reopening of the exemption period, subsequent representations cannot revive the dispute, and parity cannot be claimed from a different statutory regime without challenging the relevant amendment.
