Justice Raphael Nii Amaa Ollennu holds the record for the shortest presidential term in Ghana's history, serving as Acting President for just 24 days from August 7 to August 31, 1970. He assumed this role, overseeing the transition from military to civilian rule after Lt. Gen. Akwasi Afrifa, during a period when Ghana was establishing its Second Republic. Ollennu, a distinguished legal scholar, former Supreme Court judge, and Speaker of Parliament, handed over power to the elected President Edward Akufo-Addo. His brief but significant tenure ensured constitutional stability before a new elected president took office, cementing his unique place in Ghana's political landscape.
