Tribunal discretion to admit additional grounds and remand matters when retrospective rule changes unsettle the original relief basis

A tribunal may allow a party to raise additional grounds when those grounds were substantially urged earlier and their consideration is needed for effective justice. The retrospective amendment to Rules 9 and 49 made the captive-consumption basis of relief untenable, so the prior relief order could not stand. Because other substantive grounds had been raised but not adjudicated by the appellate authority, the matter was remanded for fresh decision on those remaining grounds, with both sides given an opportunity to lead and rebut evidence.

Issues: (i) Whether the Tribunal could permit the respondents to urge grounds not specifically dealt with by the appellate authority; (ii) Whether, after the retrospective amendment to Rules 9 and 49, the matter required remand for de novo decision on the other grounds raised by the respondents.

Issue (i): Whether the Tribunal could permit the respondents to urge grounds not specifically dealt with by the appellate authority.

Analysis: The Tribunal has wide powers to allow either party to raise additional grounds in attack or defence, and the exercise of that power depends on sound judicial discretion to do full and effective justice between the parties. The grounds now sought to be urged were found to have been substantially raised earlier before the appellate authority, even though no separate finding had been recorded on them.

Conclusion: The Tribunal could permit the respondents to urge those grounds.

Issue (ii): Whether, after the retrospective amendment to Rules 9 and 49, the matter required remand for de novo decision on the other grounds raised by the respondents.

Analysis: The retrospective amendment made the captive-consumption basis of relief untenable. Since the respondents had also raised other substantive grounds, and those grounds had not been adjudicated by the appellate authority, justice required that the appeal be reconsidered on those grounds. The matter was therefore directed to be decided afresh by the appellate authority with opportunity to both sides to lead and rebut evidence.

Conclusion: The order of the appellate authority was set aside and the matter was remanded for de novo adjudication on the remaining grounds.

Final Conclusion: The departmental appeal succeeded to the extent that the earlier relief order could not stand, but the dispute was not finally decided on merits and was sent back for fresh disposal.

Ratio Decidendi: A tribunal may permit additional grounds where they were substantially raised earlier and their consideration is necessary for effective justice, and where an earlier basis of relief is rendered untenable by retrospective amendment, remand for fresh adjudication on remaining grounds is appropriate.
