Nwaoboshi, before today, was sentenced to seven years in jail for offences of fraud and money laundering.
In a lead judgment by Justice Emmanuel Agim, the apex court held that Nwaobishi and the two companies were unjustly and maliciously prosecuted by the EFCC for committing no offences known to law.
The court said EFCC subjected them to needless criminal trial in relation civil transaction.
They were then re-arraigned before Chukwujekwu Aneke on October 5, 2018.
The EFCC accused Nwaoboshi and his companies of illegally acquiring a property named Guinea House on Marine Road, in Apapa, Lagos, for N805 million, property said to belong to the Delta State Govt.
The anti-graft agency had claimed that part of the money paid for the property was transferred by Suiming Electrical Ltd on behalf of Nwaoboshi and Golden Touch Construction Project Ltd, adding the funds are believed to be proceeds of their illicit activities.
