The bench, comprising Justices Christine Meoli, Edward Muriithi and Martin Muya, will sit in Mombasa.
A statement from the Judiciary says Mutunga’s decision was reached after Silas Otuke filed a case in the High Court claiming that the Constitution and the Elections Act had been violated.
On May 14, Justice Muriithi ruled that he matter raised substantial constitutional questions of law that warranted consideration by a three-judge bench.
Kampala University where the Governor undertook his studies has since said that the degree is authentic, contrary to claims by the National Council for Higher Education of Uganda.
The council had recommended the withdrawal of the degree which it said did not meet the required academic standard.
The institution’s Vice Chancellor Badru Kateregga on May 18 said no authority in Uganda other than the university was vested with the mandate to recall its degrees.
He had pointed out that as far as the Kampala University Senate was concerned, the degree awarded to Joho is genuine and it would neither revoke nor cancel it.
“This is a very bright student and that is why he managed to get a Second Upper class where others jumped with lowers and passes. The same was genuinely awarded and Kampala University Senate cannot and will not recall, cancel or revoke an award it deems valid,” he said.
“We wish to correct the distortions and falsehoods peddled thus far, by categorically stating that absolutely nobody and no authority in Uganda is vested or clothed with the legal power and mandate to recall or cancel or revoke Hassan Ali Joho’s degree apart from Kampala University’s Senate.”
