Concise News understands that the argument began after they had entered into appearance in the case, not clear what led to argument but Umar was seen shouting at her.
Duke wanted to make an observation but Umar said, “Sit down, I am leading.”
At this point Danladi Umar, CCT chairman, intervened and asked what the problem was.
A police officer moved to give a microphone to Duke to speak but Umar snatched the microphone.
Umar said: “She wants to address the tribunal but I have not given her permission to do that.”
In an attempt to explain herself to the CCT chairman when she had the chance, she was not audible.
Thereafter, the lead counsel to the federal government applied that her name be removed from appearance.
“I want to apply that her name be withdrawn from appearance,” he said.
Ruling on the application, the CCT chairman said Duke should “take her leave or take her seat at the back bench.”
After Umar’s ruling, she left. Both prosecution and defence adopted their addresses after which a date for judgement was fixed.
