GST registration may be cancelled for continuous non-filing of returns under Section 29, but cancellation does not extinguish pre-cancellation tax liabilities. Rule 22 requires notice and an opportunity to respond; where pending returns are filed and tax, interest and late fee are fully paid before cancellation, the officer must drop proceedings. Post-cancellation revocation under Rule 23 requires compliance with prescribed filing, payment and limitation conditions, while appellate authorities cannot exceed statutory condonation limits. Defective notices, absence of reasons, denial of meaningful hearing, or unexplained retrospective cancellation may invalidate the process. Conditional restoration may be available in appropriate non-fraud cases upon full regularisation of returns, tax, interest, late fee and penalty.
