Rectification vs review: assessing authority lacks power to reopen finalized tax assessments; appellate remedy available.

The assessing authority distinguished between rectification of manifest errors and review of a finalized assessment, concluding it lacked power to review a completed tax assessment merely because the assessee later adjusted claimed input tax credit; the court emphasised the boundary between corrective filings and reopening concluded assessments and noted the availability of appellate remedy to challenge assessment orders.
