  "summary": "INEC chairman Mahmood Yakubu reported on 26 Oct 2022 that ABIS cleaning of 2021–22 registrations identified 2,780,756 (22.6%) double, underage or fake entries, leaving 9,518,188 valid new registrants.",

  "account": "The date is that of Professor Mahmood Yakubu's address to political parties in Abuja, reproduced by the Nigerian Democratic Report. He said the Continuous Voter Registration data (28 June 2021 to 31 July 2022) was cleaned with the Automated Biometric Identification System (ABIS). This identified 2,780,756 registrations (22.6%) as ineligible and invalidated them. Among them were double or multiple registrants, underage persons and fake registrations failing INEC's business rules. That left 9,518,188 valid post-ABIS registrations; 23 registration officers were identified for sanctions. On 12 September 2022, INEC commissioner Festus Okoye said 1,126,359 of 2,523,458 registrants (28 June 2021 to 14 January 2022) were found invalid and delisted. ABIS processing of later registrations was ongoing (Punch). BusinessDay later argued that some fake and underage registrants evaded ABIS and that invalidation rates were regionally lopsided. The vendor of ABIS is not named in the sources.",

This identified 2,780,756 registrations (22.6%) as ineligible and invalidated them. Among them were double or multiple registrants, underage persons and fake registrations failing INEC's business rules. That left 9,518,188 valid post-ABIS registrations; 23 registration officers were identified for sanctions. On 12 September 2022, INEC commissioner Festus Okoye said 1,126,359 of 2,523,458 registrants (28 June 2021 to 14 January 2022) were found invalid and delisted. ABIS processing of later registrations was ongoing (Punch). BusinessDay later argued that some fake and underage registrants evaded ABIS and that invalidation rates were regionally lopsided.

He said the Continuous Voter Registration data (28 June 2021 to 31 July 2022) was cleaned with the Automated Biometric Identification System (ABIS). This identified 2,780,756 registrations (22.6%) as ineligible and invalidated them. Among them were double or multiple registrants, underage persons and fake registrations failing INEC's business rules. That left 9,518,188 valid post-ABIS registrations; 23 registration officers were identified for sanctions. On 12 September 2022, INEC commissioner Festus Okoye said 1,126,359 of 2,523,458 registrants (28 June 2021 to 14 January 2022) were found invalid and delisted. ABIS processing of later registrations was ongoing (Punch). BusinessDay later argued that some fake and underage registrants evaded ABIS and that invalidation rates were regionally lopsided. The vendor of ABIS is not named in the sources."

He said the Continuous Voter Registration data (28 June 2021 to 31 July 2022) was cleaned with the Automated Biometric Identification System (ABIS). This identified 2,780,756 registrations (22.6%) as ineligible and invalidated them. Among them were double or multiple registrants, underage persons and fake registrations failing INEC's business rules. That left 9,518,188 valid post-ABIS registrations; 23 registration officers were identified for sanctions. On 12 September 2022, INEC commissioner Festus Okoye said 1,126,359 of 2,523,458 registrants (28 June 2021 to 14 January 2022) were found invalid and delisted. ABIS processing of later registrations was ongoing (Punch). BusinessDay later argued that some fake and underage registrants evaded ABIS and that invalidation rates were regionally lopsided. The vendor of ABIS is not named in the sources.",
