Amadi, who is retiring, handed over governing documents to the Deputy Chief Registrar of the judiciary, Paul Maina.
"We are grateful for the service that you have rendered to this country and for seeing NCAJ from nothing when it was established with no infrastructure, human resource or money, to see it standing where we are today," said Koome.
Appointment
She was appointed on a five-year renewable contract in January 2014, taking over from Gladys Boss Shollei.
Amadi made several milestones during her tenure that saw a progressive transformation of the judiciary. She administered the oath of office to former President Uhuru Kenyatta in 2017 and William Ruto in 2022.
The High Court advocate signed off on November 24 to proceed to a terminal leave.
Law Journey
Her professional journey started when she graduated with a Bachelor of Laws Degree from the University of Nairobi, and later a post-graduate diploma in legal practice from the Kenya School of Law.
She was admitted to the bar in 1987 and later joined the judiciary as a district magistrate 2 in 1990.
Amadi has been an advocate of the High Court of Kenya since 1989 and has risen through the ranks over the years.
Gold Scam
She was implicated in a gold scam case in May 2023, a case involving Bruton Gold Trading, a gold firm registered in Dubai that was allegedly conned by Sh102m.
