Registrar's re-submission timelines require correction on request or forms are treated invalid, preserving procedural clarity. The rules empower the Registrar to call for further information or identify defects in Form STK-2 and require the applicant to remove defects and re-submit within specified limited periods, failing which the Registrar shall treat the Form as invalid in the electronic record; any re-submission prior to these amendments will not count toward the maximum number of re-submissions. The amendments also substitute Forms STK-1, STK-5 and STK-5A, prescribing the content of notices for proposed removal, public notices inviting objections, and web-linked listing procedures.
