1504.9 The failure of the circulator of a nominating petition or individual petition sheets to meet the petition circulator requirements set forth in § 1503.1 shall invalidate the signature of an otherwise registered qualified elector.
1504.10 An address on a petition which is different than the address which appears on the Board's records shall be deemed valid if the signer's current address is within the District of Columbia and the signer files a change of address form with the Board during the first 10 days of the period designated for resolving challenges to petitions.
