Akpoti-Uduaghan presented her case at an IPU meeting held at the United Nations headquarters in New York on Tuesday.
She was suspended from the senate on March 6 for “gross misconduct” following her seating arrangement altercation with Senate President Godswill Akpabio.
Tulia Ackson, IPU president, acknowledged the concerns raised by Akpoti-Uduaghan and assured that the organisation would investigate the matter thoroughly.
She said the IPU would listen to both sides of the issue before taking any necessary steps.
Ackson recognised that another Nigerian delegate, Kafilat Ogbara, a member of the house of representatives, had requested to speak but was unable to due to time constraints.
“I would like to say we have heard her concerns, and having heard her, it would have been an opportunity for all of us to understand more about what she has said,” Ackson said.
“But because we listened only on her side, as an institution as IPU, we will be taking the concerns that have been raised, not only taking her side, but also giving a chance to listen to the other side, as it is a custom for IPU.
“After having listened to the other side, we will take steps as necessary. So I thought it was necessary for us to say a word about it and then be able to take it further.”
The IPU is a global organisation of national parliaments. It promotes peace, democracy and sustainable development among nations through diplomacy and dialogue.
It also seeks to strengthen international parliaments and make them more effective.
