He began his law career at Olisianunba Chambers, a law firm owned by his father. In 1990, he established a partnership firm called Metuh, Okafor & Associates, where he served as the managing solicitor.
In 1991, he was appointed as the chairman of Legend Properties Limited, a property management firm.
In 1996, he established a law firm, Olisa Metuh and Co., to provide services in legal practice, real estate and share acquisitions.
Political life
He began his political career as the coordinator of the Igbo United Congress. While serving in that capacity, he was also a member of the finance committee of People's National Forum (PNF).
He served as a pioneer member of the national finance committee of the Peoples Democratic Party.
In November 1999, at the first National Convention of the PDP, he was elected as ex officio member of the National Executive Committee (NEC) of the party.
He later acted as the secretary of the National Peace and Reconciliatory Committee of the party for two years.
In 2002, he was appointed as the chairman of the Cross River State electoral panel.
"From the records, Metuh got over N400 million, he has not said anything because we need the public money to be returned so that it's going to be used for public good," Mr. Ibrahim Magu said during a meeting with online media publishers in Lagos.
On 5 February 2018, Metuh arrived at the Federal High Court in Abuja in an ambulance. He was absent when the case was heard the previous week.
Conviction
On 25 February 2020, the Federal High Court convicted Metuh and sentenced him to seven years' imprisonment after finding him guilty on charges relating to money laundering. The court also ordered the forfeiture of the ₦400 million involved in the case.
Release
Metuh appealed the conviction. On 16 December 2020, the Court of Appeal in Abuja nullified the trial court's judgment, citing bias by Justice Abang (who had made disparaging remarks against Metuh in the ruling, including references to petitions filed against him). The appellate court ordered a fresh trial before another judge and Metuh was subsequently released from Kuje Prison after serving about 10 months.
In September 2022, a Federal High Court struck out the retrial charges, describing the EFCC's approach as an abuse of process.
