Extension of time for revocation of cancelled registration clarifies eligibility, processing and limited further administrative extensions. Clarification confirms that the executive notification extends the filing deadline for revocation of cancellation of registration to a specified final date for cases whose original due date fell within the affected period, applying to cancellations under the relevant clauses and to applications at any procedural status; officers and appellate authorities must process, admit or reconsider applications accordingly, and the interplay with the proviso permitting incremental administrative extensions is clarified so that in some scenarios the notification deadline is final while in others further limited extensions may be granted by competent officers.
