Former President Muhammadu Buhari has returned to Nigeria after testifying in a high-profile arbitration case at the International Chamber of Commerce (ICC) Court of Arbitration in Paris, France.

A video shared by Bashir Ahmad, former Special Assistant on Digital Communications, showed Buhari disembarking from an aircraft upon his return.

The arbitration revolves around a $2.3 billion dispute between Nigeria and Sunrise Power, which filed the case in 2017 over an alleged breach of contract for the construction of the 3,050MW Mambilla power plant in Taraba State.

The $6 billion project was initially planned on a build, operate, and transfer basis.

Buhari’s testimony is a key component of Nigeria’s defense.

According to the presidency, witnesses, including former President Olusegun Obasanjo, have provided voluntary testimony.

The dispute originates from a 2003 contract and a subsequent 2020 settlement agreement, which Sunrise Power claims the Nigerian government failed to honor.

Both Buhari and Obasanjo have denied authorizing any agreements or settlements related to the project.
