The Nigerian government had laid charges of treason against Kanu, including 15 fresh charges which were filed on Monday.
Magaji stated this while speaking with journalists at the court premises after the trial was adjourned to February 16.
The lawyer, who brought two prosecution witnesses to court on Wednesday, expressed disappointment that the trial could not begin immediately.
According to him, the defence team ambushed the court with an application for bail and another application seeking to quash the charges against Kanu.
Magaji added that Kanu “vehemently” denied being an IPOB member in court.
He said, “One of the charges suggesting that the defendant, Nnamdi Kanu is a member of IPOB and he vehemently denied being a member of IPOB. That is very curious and we urge Nigerians to see us through how we are going to prove all those charges against the defendant in no time to come.”
Kanu had on Wednesday pleaded not guilty to the 15-count amended charge bordering on treasonable felony and terrorism, brought against him by the Nigerian government.
He said he was innocent of all the allegations the government leveled against him after the charge was read to him in the open court.
The Buhari-led government had filed fresh terrorism charges against the detained IPOB leader before the Federal High Court in Abuja
Consequently, the action increased the initial counts against him from seven to 15.
But during his trial on Tuesday which was held amid heavy security presence, Kanu objected to the fresh charges. The case was then adjourned till Wednesday for him to take his plea.
Kanu on Wednesday entered his plea to the fresh amended charge against him which borders on his alleged commission of acts of terrorism, felony, incitement, unlawful importation of a radio transmitter, and headship of an illegal organisation.
