i) Invalidity of Section 8 notice: First and foremost, the total claim made in the statutory demand notice served on the Corporate Debtor u/s 8 is intrinsically linked to and is based on defaults which, without a doubt, occurred during the period excluded u/s 10A. It is trite, that service of a valid notice u/s 8 is a sine qua non for filing application u/s 9. Further, in view of the judgment of Hon'ble Supreme Court in Ramesh Kymal (supra), it is also well settled now that provisions of section 10A create a complete bar on initiation of CIRP, in respect of any default that has occurred during the period of suspension of the provisions of the Code by virtue of insertion of section 10A. Since, the defaults occurring during the period of suspension of the Code make a creditor/applicant ineligible to initiate CIRP in respect of such default, any notice issued u/s 8 communicating a claim which is intrinsically linked to and based on such default occurring during the excluded/suspended/prohibited period cannot be deemed to be valid. Consequently, any application filed u/s 9 of the Code based on such a notice served upon the Corporate Debtor which is intrinsically linked to and based on defaults occurring during the period of suspension of Sections 7, 9
