In the event the initial petition contained prima facie sufficient signatures, such recall petition may be supported by supplemental signatures of qualified electors signed in the manner required in Item 3 (Signatures.) of this Section appended to petitions issued, signed and filed as required for the original petition at any time within twenty (20) days after the date of the certificate of insufficiency by the Clerk of Council.  The Clerk of Council shall within ten (10) days after such supplemental petitions are filed make a like examination of them, and if his certificate shall show the same to be still insufficient he shall return it in the manner described in Item 4 (Filing and Certification.) of this Section to the person designated in such petition to receive it, without prejudice however to the filing of a new petition for the same purpose, provided that no new petition shall be filed within one (1) year thereafter.
