Amos Yohanna was on Wednesday, sworn in as the new Senator representing Adamawa North Senatorial District.
Deputy Senate President, Jibrin Barau, performed the ceremony during plenary.
Yohanna, a member of the Peoples Democratic Party (PDP) replaces Abbo, who was sacked by the Appeal Court last week Monday.
Delivering judgment on Monday, the three-member panel presided over by Justice C.E. Nwosu-Iheme, ordered the Independent National Electoral Commission to issue a Certificate of Return to Yohanna as the duly elected lawmaker representing the area in the National Assembly.
The appellate vacated the tribunal judgment which had earlier affirmed Abbo of the All Progressives Congress as the winner of the senatorial election.
INEC had declared Abbo the winner of the February 25, 2023, parliamentary election.
