The Abuja Division of the Appeal Court has discharged and acquitted Mazi Nnamdi Kanu, the detained leader of the Indigenous People of Biafra (IPOB).
The Federal government is prosecuting Kanu at the Federal High Court in Abuja for 15 count charges bordering, including treasonable felony and terrorism.
The Federal government said he committed the offences in the course of his separatist campaigns.
A three-man panel of the Court of Appeal said the Federal High Court lacks the jurisdiction to try him in view of his abduction and extraordinary rendition to Nigeria in flagrant violation of the OAU convention and protocol on extradition.
The court held that the 15-count charge preferred against Kanu did not disclose the place, date, time and nature of the alleged offences before being unlawfully extradited to Nigeria in clear violation of international treaties.
The court further held that the Federal Government failed to disclose where Nnamdi Kanu was arrested despite the grave allegations against him.
