§ 6.4. Procedure After Filing.

A. Certificate of City Clerk; Amendment.
Within twenty (20) days after a petition is filed, the City Clerk shall complete a certificate as to its sufficiency, specifying, if it is insufficient, the particulars wherein it is defective, and shall promptly send a copy of the certificate to the petitioners by registered mail. A petition certified insufficient for lack of the required number of valid signatures may be amended once, if one or more of the petitioners files a notice of intention to amend it with the City Clerk within two (2) working days after receiving a copy of such certificate and files a supplementary petition upon additional papers within fifteen (15) days after receiving a copy of such certificate. The time of filing the amendment must fall within the original petition time frame. Within fifteen (15) days after it is filed, the City Clerk shall complete a certificate as to the sufficiency of the petition as amended and promptly send a copy of such certificate to the petitioners by registered mail, as in the case of an original petition. If a petition or amended petition is certified sufficient, the City Clerk shall promptly present the certificate to the Council.

B. Validity of Signatures.
A petition shall be deemed sufficient for the purposes of this Article if it contains valid signatures in the number prescribed by Section 6.3A and is timely filed, even if the petition contains one or more invalid signatures. A valid signature need not be in the identical form in which the registered voter's name appears on the voting rolls; nor may a signature be deemed invalid because the address accompanying the name on the petition is different from the address for the same name on the current voting rolls.
