Finality Vs Reopening

This ruling is a decisive affirmation of finality in tax adjudication. 

The Tribunal rejects the Department’s attempt to re-litigate an issue already concluded through appellate hierarchy (including Supreme Court dismissal). 

It underscores that administrative implementation of an order cements finality, and subsequent reopening is impermissible. 

The decision also reinforces that refund proceedings cannot be used as a backdoor to revisit concluded assessments, aligning with settled Supreme Court jurisprudence.
